Simple Summary: This study shows that nutrients that are not digested have a significant effect on stool moisture and quality. As protein in the lower gut increased, stool moisture increased and quality decreased in both species. Also, increasing fiber in the lower gut resulted in increased stool quality and reduced moisture in both species. Both species also had a response to advancing age: in the dog, age increased firmness for the first 11 years of life, while in the cat, age increased firmness after 4 years of age. The effect of digestive bypass macronutrients and age on stool quality (moisture and firmness) in dogs and cats is not well understood. Data were analyzed from digestibility tests (n = 2020, 361 dogs and 536 cats) including dry and wet product types. Both food and feces were measured for moisture and nutrients according to standard protocols; stool firmness was graded. Linear mixed modeling was used to evaluate the associations between nutrient bypass, age and stool quality. Bypass protein increased stool moisture (dog, cat p < 0.0001) and decreased firmness (dog p = 0.01, cat p < 0.0001), while bypass fiber decreased stool moisture and increased firmness (dog, cat p < 0.0001 for both). Both species manifested a negative quadratic effect of advanced age on stool firmness (dog p < 0.0001 and cat p = 0.02). However, the association of advanced age (quadratic effect) with metabolizable energy required to maintain body weight was different between species; dogs had a positive association (p = 0.028), while it was negative for cats (p < 0.0001). Taken together, these data may aid in the development of food formulations for companion animals, which can better meet changing nutritional needs across life stages. [ABSTRACT FROM AUTHOR]

Simple Summary: This study explored how people's relationships with their dogs were associated with mental health and how this compared to their relationships with other humans. Our results found that owners who had a strong attachment to their dogs tended to have poorer mental health outcomes. The connection between a strong attachment to dogs and poor mental health may be partly due to these owners having an anxious attachment style towards other people, suggesting these owners may turn to their dogs for emotional support due to a lack of dependable human connections. The relationship between a strong attachment to dogs and poorer mental health was also influenced by gender, with this relationship being significant for women, but not for men. Together, these results highlight a potential risk to mental health for owners who rely on their strong bond with their dogs to compensate for feeling anxious about their relationships with other humans. For these owners, it may be worth considering how they can improve their connections with other humans to be able to better support their mental health. It is unclear how pet ownership is related to mental health, with some previous research suggesting pet owners have better mental health, while other research suggests they have worse mental health. Some researchers have suggested that it may be more useful to investigate the bond people feel with their pets and how this may impact mental health; however, this too has led to mixed results. This study examined how owners' attachment to their dogs was associated with mental health and how this compared to their attachment relationships with other humans in a sample of 607 dog owners. Our findings indicate that both strong and insecure attachments to dogs are linked to poorer mental health outcomes, as was having an insecure attachment style in their human relationships. The adverse impact of strong attachment to dogs on mental health was mediated by these owners having an anxious attachment style toward other people, which in turn was associated with poorer mental health. The relationship between a strong attachment to dogs and poorer mental health was also moderated by gender, with this relationship being significant in women but not significant for men. Together, these results suggest a possible risk to mental health for owners who form a strong attachment to their dogs to compensate for anxious attachments in human relationships.

Simple Summary: Choosing the right dog that fits well with an owner's lifestyle is important for the happiness of both the dog and the owner. This study looked into why and how people in Austria choose their dogs by surveying over a thousand dog owners. Unlike past studies, we asked open-ended questions so that the owners could freely share their reasons. On average, the owners gave two to three reasons for their choice. The most common reasons included the dog's breed, picking a dog on a whim, the dog's abilities for work or sports, and rescuing a dog. Surprisingly, less than 1% of owners prioritized guarding abilities, and 1% considered basic traits like the dog's sex, age, or health as key factors. If an owner picked a dog for its looks or skills, they often chose their next dog for the same reasons. Factors like the owner's age, household composition, previous experience with dogs, and the intended role of the dog also played a part in the decision. For instance, owners with children preferred dogs that were friendly, calm, and easy to train, and they were less likely to adopt from shelters compared to those without children. Overall, our study shows the wide range of reasons that people have for choosing their dogs, which can help ensure better matches between dogs and their owners, improving the well-being of both. Selecting a dog that is incompatible with the owner's expectations can negatively impact both parties. Previous studies on dog acquisition have primarily focused on shelter environments, using closed-ended questions to assess hypothetical preferences. In contrast, our study employed open-ended questions with a convenience sample of Austrian dog owners (N = 1077) to retrospectively explore why the owners chose their dogs. We also examined consistency in owners' responses and the influence of owner characteristics (age, education, household composition, previous dog experience, purpose of acquisition) on their reasons. Content analysis revealed 24 codes; the frequency of codes was 2.4/response. The most frequent codes were breed-based choice (29%), choosing on a whim, without careful consideration (24%), work/sport skills (22%), and rescuing a dog (17%). The least frequent were the age (1%), health (1%), sex (1%), and guarding skills (0.6%) of the dog. Twelve codes were consistent over time, and ten were consistent across dogs, indicating that the owners showed a consistent preference for certain traits. Except for the owner's education level, all characteristics affected the likelihood of mentioning at least one code. Most associations were found with the presence of children in the household: owners with children preferred friendly, easily manageable, and easy-to-train dogs and were less likely to adopt or rescue compared to owners living without children. Our findings also highlight discrepancies between spontaneous (free-text) reports and responses to closed-ended questions, underscoring the importance of qualitative data in better understanding the motivations behind and the factors influencing dog acquisition.

Simple Summary: This study investigates the reasons behind the relinquishment of companion animals, specifically cats and dogs, to an open-admission shelter in the US. We analyzed 2836 randomly selected owner relinquishment records over a six-year period (2018–2023) using content analysis, a systematic method for categorizing qualitative data. The most common reasons identified for relinquishment included behavioral issues (28%), housing/moving (18%), and the inability to care for the animals (16%). Aggression, social conflict, and soiling were the most common behavioral-issue reasons reported. However, differences were observed in the pattern of relinquishment reasons based on statistical analyses of species, type of relinquishment, and year. The study found no significant increase in relinquishments due to financial or housing pressures during the peri-pandemic period, but there was an increase in relinquishments due to owners being otherwise unable to care for their pets in 2022 and 2023. This research provides valuable insights for animal welfare organizations and policymakers to develop strategies to better understand animal relinquishment and improve the welfare of both animals and their owners. The relinquishment of companion animals to shelters presents significant challenges for animal welfare organizations and has substantial implications for the well-being of both the animals and their owners. This study aims to investigate the reasons for voluntarily relinquishing animals to shelters, to examine species-specific differences (cats and dogs), to compare initial relinquishments to returns (re-relinquishments or readmissions), and to identify potential changes over a 6-year period framing the onset of the COVID-19 pandemic. A retrospective analysis of owner relinquishment records from an open admission shelter in the US was conducted using content analysis, a novel approach in this area of research. A total of 13 relinquishment reason categories were identified, as well as 9 separate categories for specific behavioral issues. Among 2836 randomly selected records, the most frequent reasons cited were Behavior Issues (28%), Housing/Moving (18%), Unable to Care (16%), Too Many Pets (10%), Financial (6%), and Owner Allergies (5%). The most common behavioral reasons reported were Aggression (32% of behavioral surrenders), Social Conflict (28%), and Soiling (13%). However, differences were observed in the pattern of relinquishment reasons based on statistical analyses of species, type of relinquishment, and year. Regarding temporal trends, Housing/Moving and Financial reasons were not found to have changed significantly since the pandemic, but the relative frequency of the category Unable to Care increased significantly in 2022 and 2023. Collectively, these findings partially replicate those from research spanning the past several decades in this area that has employed less systematic methodology and can further be used to help identify and understand the primary drivers of owner relinquishments.

Simple Summary: European citizens' perception of dogs and cats has shifted, calling for a more robust and appropriate approach to protect the welfare of these pets. While recent updates to EU legislation have aimed to improve some aspects of companion animal welfare, these measures remain insufficient and lack harmonization across Member States. The existing legal framework still falls short of establishing a comprehensive, high standard of care and protection for these animals. Key issues include unhealthy and unethical breeding practices, irresponsible sale and ownership, the complexities of transporting animals for both commercial and non-commercial purposes, and inadequate regulations on training methods and working dog conditions. Additionally, there are concerns about the regulation of dog and cat shows, competitions, therapeutic neglect, end-of-life care, shelter management, and the rights of free-ranging cat and dog populations. To address these issues more effectively, there is a need for more consistent legislation across Europe, coupled with increased education and awareness of responsible pet ownership. The One Welfare approach, which emphasizes the interconnectedness of human and animal welfare, could also play a crucial role in bridging these legislative gaps, ensuring that the human–animal bond is better integrated into modern society's welfare considerations. However, despite these efforts, many challenges remain unresolved, highlighting the need for further legislative action and societal engagement to fully protect companion animal welfare. Companion animals, especially dogs and cats, have increasingly been recognized as moral subjects and valued as family members by European citizens. This new role encourages policy makers to face the many companion animals' welfare issues not yet covered by the EU legislation. The main gaps in the protection of dog and cat welfare during their all lifespan have been identified: unhealthy and unethical breeding practices, irresponsible sale and ownership, transport for commercial and non-commercial purposes, training methods, working dog conditions and rights, regulation of dog and cat shows and competitions, the therapeutic neglect, dog and cat end-of-life care, shelter management legislation and the free-ranging cat and dog population rights. The EU legislation framework is still very weak and far from establishing a harmonized approach, promoting a high standard of care and protection across Member States. We conclude that education and awareness regarding responsible pet ownership and the need for a One Welfare approach have a high value in finding adequate solutions, especially when poor human social welfare affects companion animal welfare. Given the link between human and companion animal welfare, the use of stakeholders' involvement strategies and a transdisciplinary approach appear crucial for the development of an EU legal framework for the well-being of dogs and cats.

Simple Summary: The diagnostic value of anti-Müllerian hormone (AMH) is well established but less is known about physiological concentrations in young individuals. The aim of this study was to determine AMH levels in small animals before and around puberty and to correlate these levels with testosterone in males entering puberty. Blood samples were collected between 2 and 48 weeks after birth for AMH and testosterone measured using a chemiluminescence immune assay. AMH concentrations were higher in males than in females, with no significant differences among male individuals. However, queens had significantly higher AMH concentrations compared to bitches. A significant decreased in AMH was observed in the males beginning 24 weeks after birth, which correlated only in dogs with an increase in testosterone. In bitches, AMH remained below the detection limit until 16 weeks after birth after which it increased slightly. In queens, AMH was detectable from week 2 with a significant increase starting at week 8, even approaching the chemiluminescence immune assay's upper limit. In conclusion, queens secreted AMH much earlier and in significantly higher amounts than bitches. The decrease of AMH in male species entering puberty was observed in both dogs and tomcats, but a negative correlation with testosterone was derived only for male dogs. In recent years several studies established the diagnostic value of anti-Müllerian hormone (AMH) in companion animals. However, less is known about physiological AMH concentrations in young individuals highlighting the necessity to apply the diagnostic findings to this group. The aim of this study was to determine the AMH values of healthy male and female dogs between the age of 8 and 48 weeks, tomcats under 8 weeks and up to 48 weeks of age and queens between 2 to 12 weeks of age. In total, 96 blood samples were collected. Anti-Müllerian hormone was measured in all samples and testosterone was measured in the oldest age group of the males in both species. The hormones were analyzed using a human based chemiluminescence immune assay. Overall, AMH concentrations were higher in males than in females (p < 0.001). According to the AMH concentration there was no difference in males, but queens had significant higher AMH concentrations than bitches (p < 0.001). AMH remained high in males up to week 24 and decreased significantly thereafter (tomcats: p = 0.015; male dogs: p = 0.013), which correlated with an increase in testosterone levels for male dogs only. In bitches, AMH remained below the detection limit until the week 16 and slightly increased subsequently. In queens, AMH was detectable from the beginning with a significant increase in the older age group (p = 0.003). Half of the cats in the older age group even approached the chemiluminescence immune assay's upper limit. The results show that female cats secrete AMH much earlier than female dogs in which AMH secretion begins just shortly before the start of the puberty. In the male animals, the decrease in AMH concentration around puberty was similar in dogs and cats, but a correlation with the increase of testosterone was only observed in dogs. Further research is required to determine the origin of the high AMH concentrations in female kittens and the lack of correlation between testosterone and AMH concentrations in male kittens.

Simple Summary: Factors affecting dog owners' compliance with veterinary medication recommendations were examined, and barriers and aids to administering medications were identified. Findings revealed that older dogs had more compliant owners, and clients who used no aids for medication were more likely to be compliant. Almost half of owners reported not being shown how to administer the medication, and one-third faced challenges, mainly due to resistant pets. Nearly half of the surveyed clients were noncompliant, which is higher than previously reported in other studies. Our study highlights the necessity of enhancing client compliance with veterinary medication instructions for dogs. It emphasizes the importance of providing standardized instructions and guidance, including demonstrating how to administer medications. Ensuring that prescribed oral medications are palatable and easy to administer before patient discharge may contribute to improved patient outcomes. Client compliance with prescribed medication instructions to treat their pets is a concern. This study describes factors associated with the noncompliance of dog owners with veterinary recommendations for medication, as well as client-reported barriers and aids to administering medications. A cross-sectional survey of dog owners' compliance with veterinary medication recommendations was performed from 9 January 2019 to 18 July 2020. A convenience sample of owners who prescribed medication for their dogs during or following elective veterinary examination was surveyed regarding medication administration experience and compliance. Owners were followed up to determine if the course of medication had been completed. Compliance data were analyzed descriptively. Logistic regression was performed with compliance as the outcome. Medication noncompliance was recorded for 47% (71/151) of owners. Increasing dog age was associated with better owner compliance (p < 0.05). Pet owners who used "nothing" as an aid to medicating were less likely to be noncompliant (p < 0.05). Forty-seven percent (71/151) of owners reported that "nobody" showed them how to administer the medication. One-third of dog owners (47/151) reported challenges in medicating their pets. The most common reason cited by clients reporting challenges was a resistant pet. Demonstration of medication administration techniques and discussion about available aids to medicating a pet may improve client compliance. [ABSTRACT FROM AUTHOR]

Simple Summary: Companion animals continue to be relinquished by their guardians to shelters. Historically, animal behavior has been seen as the main cause for companion animals to be relinquished. Therefore, we wanted to understand whether companion animals are relinquished due to issues related to the animal themselves or due to challenges in the companion animal's guardian's life. Previous research indicates that socioeconomic difficulties of the guardian, such as financial constraints and inadequate housing, contribute to companion animal relinquishment. Relinquishment data are crucial for a better understanding of how socioeconomic factors intersect with the care of companion animals. This study analyzed relinquishment data from five Australian shelters over the period of Australian Financial Years (FY July 1 to June 30) 2018/19 to 2022/23 and analyzed data on the 46,820 companion animals relinquished. The most common reason for relinquishment was housing for both low and high socioeconomic groups. Financial constraints were reported more in lower socioeconomic groups, whereas healthcare of the human as a reason for relinquishment was greater in the higher socioeconomic groups. This highlights the need for comprehensive, cross-disciplinary strategies that address both human and animal welfare needs holistically. Such integrated approaches can improve outcomes for companion animals and their human caregivers by addressing the underlying socioeconomic factors affecting their well-being. It is important to understand the reasons for companion animal relinquishment to help reduce the financial and ethical problems arising from too many dogs and cats in shelters. This study investigates the socioeconomic factors and reasons behind companion animal relinquishment in Australia, utilizing data from five animal shelters, over a five-year period (Financial Year 2018/19 to 2022/23). Descriptive statistics reveal that the median Index of Relative Socio-Economic Advantage and Disadvantage (IRSAD) decile of companion animal guardians who relinquished their companion animal was decile 4 out of 10, indicating that they live in areas of lower-than-average socioeconomic status. Cats accounted for 59.4% and dogs for 40.6% of all relinquishments, with more relinquishments from lower socioeconomic deciles (1–5) (cats: 62.6%, dogs: 65.8%). The median age of relinquished cats was 5 months and dogs 16 months, with human factor-related issues (e.g., Housing, Financial Constraints, Human Healthcare) cited in 86% of cases. Descriptive analysis for the five financial years shows a declining trend in numbers of relinquishments, with housing issues (31.2%) identified as the primary reason, followed by ownership decisions (16.2%), financial constraints (11.2%), and human health issues (10.4%). Comparing the reasons for relinquishment between lower (decile 1–5) and higher (decile 6–10) socioeconomic status demonstrated that financial difficulties were a more common reason in lower vs. higher socioeconomic groups, while human health and family-related issues are more common in higher vs. lower socioeconomic groups. These findings highlight the critical role of socioeconomic factors in understanding why people relinquish their companion animals, which can inform targeted interventions to support companion animal welfare across different socioeconomic backgrounds.

Simple Summary: This qualitative study explores human–dog relationships with a focus on communication dynamics. Twelve human–dog dyads were analyzed using narrative interviews and cooperative tasks. The results suggest that human expectations shape interactions, transforming dog ownership into a family-like role. Effective communication relies on both verbal and non-verbal cues. Empathy is critical for deeper emotional connections. This study highlights that compatibility between humans and dogs has a significant impact on relationship satisfaction. This exploratory study examines the complex dynamics of human–dog relationships and their impact on interspecies communication. Twelve human–dog dyads were studied using narrative interviews to explore how people perceive their relationships with their dogs. In addition, the dyads engaged in a cooperative task to observe interaction dynamics during everyday activities. This study shows that individual expectations frame interactions and that traditional notions of dog ownership are evolving into more family-like relationships. Effective communication relies on a nuanced mix of verbal and non-verbal cues, with empathy emerging as a fundamental element guiding these interactions. Our findings underline the profound influence of human expectations, knowledge and empathy on communication with dogs. They also highlight the critical role of compatibility between human and dog dyads, and emphasize that such compatibility is a key determinant of satisfaction in interspecies relationships. These findings contribute to a deeper understanding of how human factors modulate communication and satisfaction in human–animal interactions. [ABSTRACT FROM AUTHOR]

Simple Summary: The nutritional needs of kittens are normally met by the queen, but sometimes unfavorable events such as maternal behavior, blood incompatibility and maternal agalactia occur that make it necessary for breeders to use milk replacer for feeding. As the breeding of domestic cats grows, so does the demand for specialized kitten formula. The aim of this study was to investigate the effects of an experimental milk replacer (EMR) on growth, gut microbiology, immune antioxidant capacity and nutrient metabolism in kittens. The results revealed that this EMR not only increases the growth rate of kittens in the late lactation period but also modified the composition of the gut microbiome, improved antioxidant capacity and activated lipid metabolic pathways. These insights are pivotal for optimizing milk replacers for kittens, thereby addressing challenges in feline neonatal nutrition. With the rising popularity of pet cats as companion animals, the survival of newborn kittens is often threatened by factors such as inadequate nursing, maternal behavior and blood incompatibility. These challenges require the use of milk replacers for nurturing. To investigate the effects that feeding kittens with an experimental milk replacer (EMR) have on growth and development, intestinal microbiota, immune response and nutrient metabolism, 12 British shorthair kittens were randomly divided into two groups after nursing for the first week of life. Kittens were fed queen's milk or EMR, whereby kittens fed queen's milk served as the control (CON) group. The findings revealed that the CON group exhibited superoxide dismutase (SOD) activity and total antioxidant capacity (T-AOC) (p < 0.01) on day 7. However, the EMR group had better growth performance during the later stage of the experiment (p < 0.05); the immunocompetence and antioxidant capacity of the EMR group were not significantly different from those of the CON group in the middle and late stages of the experiment, and the mean values of all the indexes were slightly better than those of the control group. Sequencing of the 16S rRNA gene in microbiota demonstrated that EMR increased the colonization of bacterial genera, including Lachnospiraceae, Enterococcus, Rothia and Ligilactobacillus. Compared to the CON group, acetate acid (p < 0.05), propionate acid (p < 0.01) and total SCFAs (p < 0.01) in the EMR group were significantly increased. Moreover, the intake of the EMR resulted in the production of distinct metabolites implicated in the metabolism of lipids and amino acids, among other nutrients, thus invigorating the associated metabolic pathways. These results elucidate the impact of administering a milk replacer on gastrointestinal health and nutrient assimilation in kittens. The study provides insights into the use of milk powder alternatives and sets the stage for future research on the formulation and effectiveness of kitten milk replacers. [ABSTRACT FROM AUTHOR]

Simple Summary: Companion animal caregivers who have stronger attachment bonds to their companion animals ascribe more complex emotions and cognitions to them compared to those with lower levels of attachment. We examined whether the experience of caring for cats, caregiver attachment, and style of attachment (avoidant, anxious) predicted greater attributions of primary and secondary emotions and cognitive abilities to companion cats. Those with avoidant attachment styles perceived fewer primary emotions in their cats, whereas those with stronger attachment strength perceived their cats to express more secondary emotions and cognitive capacities. Both cat-caregivers and non-cat-caregivers with greater beliefs in animal minds perceived more complex secondary emotions and cognition. Attitudes toward animals predicted only the attribution of primary emotions, and housing cats indoors or outdoors did not uniquely predict attributions. As with previous studies, the type and strength of the bond formed with companion cats is strongly associated with the way caregivers perceive their thoughts and feelings, which likely impacts feline welfare. Our findings suggest that our general liking for animals is less important than our bonds with specific animals in shaping our thoughts about their minds. Companion cat caregivers ascribe complex emotions and cognitions to their cats, and these attributions are greater with a stronger attachment to their animals. We compared attributions of emotional and cognitive complexity to cats in cat caregivers and non-caregivers. We measured attitudes toward animals, belief in animal minds, caregivers' strength of attachment, and attachment style with a particular companion cat in 448 university students, of whom 251 had owned a cat. We asked the extent to which respondents thought that cats were capable of expressing primary and secondary emotions and cognitive capabilities. Caregivers significantly differed from non-caregivers only in the attribution of primary emotions. Belief in animal minds predicted the attribution of secondary emotions and cognition. For caregivers only, avoidant attachment style was negatively associated with the attribution of primary emotions, whereas attachment strength was positively associated with the attribution of secondary emotions and cognition. These abilities may have greater discriminatory power as most respondents ascribe primary emotions to cats, perhaps for anthropomorphic reasons. Housing conditions (indoor and outdoor) were not associated with attributions, suggesting that bonds are more important than time spent together within the home in predicting the attribution of emotional and cognitive complexity in cats.

Simple Summary: The 2017 Edgecumbe flood in New Zealand triggered the largest companion animal rescue operation in the nation's history, highlighting significant gaps in disaster preparedness for animals. This study aimed to explore the experiences of six first responders from various agencies involved in the rescue efforts. The main challenges identified included the lack of logistical planning during the initial rescue phase, the need for proper animal identification and tracking systems, and the difficulties in decontaminating and providing long-term care for rescued animals. Health and safety issues for responders were also significant, with many facing hazardous conditions and emotional stress. This study concluded that comprehensive collaborative emergency response planning is essential to address the needs of both humans and animals. The findings underscore the importance of including animals in disaster preparedness plans and ensuring that responders are adequately trained and supported. These insights are valuable for improving future emergency responses, promoting community resilience, and ensuring the welfare of animals and humans during disasters. The 2017 Edgecumbe flood in New Zealand necessitated the rescue of over 1000 animals, making it the largest companion animal rescue operation in the nation's history at the time. This qualitative study explores the experiences and perspectives of six first responders from various agencies involved in the animal rescue efforts. Through semi-structured interviews, this study identified several key themes, including challenges during the rescue phase, post-rescue issues, the impact on the human–animal relationship and wellbeing, and the health and safety of responders. The rescue phase was characterised by difficulties in evacuating and rescuing animals, the influence of the socio-zoological scale on rescue prioritisation, issues with feeding animals in place, and the diversity of species requiring rescue. Post-rescue challenges included animal identification and tracking, decontamination, management of deceased animals, and long-term impacts on animals and owners. This study also highlighted the interconnectedness of human and animal welfare during the disaster, as well as the health and safety risks faced by responders. The findings underscore the need for comprehensive collaborative emergency response planning that addresses the needs of both humans and animals, as well as the importance of ongoing efforts to build resilience and preparedness in communities. Lessons learned from the Edgecumbe flood can inform future policy, planning, and practice to enhance the effectiveness and compassion of animal-inclusive emergency management. [ABSTRACT FROM AUTHOR]

Simple Summary: In this study we examined reptile pet ownership trends and animal welfare practices in Hong Kong. Over 200 owners from Hong Kong were surveyed and their responses were then used to understand the current preferences for reptile species and how these animals are cared for. The results revealed a growing popularity for reptiles, particularly lizards, among people that were acquiring their first pet reptile. Turtles remained a popular choice, likely due to cultural associations and perceived ease of care. While many owners expressed awareness of proper reptile care, which includes healthcare, diet, and living space, a concerning gap was identified between reptile care knowledge and its practical application. This was particularly evident in the under-utilization of veterinary check-ups. Interestingly, we found a potential link between the experience of owning a pet reptile and reptile health, suggesting new owners might benefit from acquiring more knowledge. Additionally, we identified a possible association between the variety of sources from which reptiles are acquired and their well-being. These findings highlight the need for more focused educational programs to equip new reptile pet owners with proper health care and nutrition practices and the importance of regular veterinary visits. By fostering collaborations and/or partnerships between reptile pet owners, veterinarians, and animal welfare organizations, the results of this study and their application aim to improve reptile welfare within the evolving pet ownership landscape in Hong Kong. We investigated the evolving landscape of reptile pet ownership in Hong Kong. Employing a quantitative approach, a self-administered survey was distributed and over 200 reptile pet owners residing in Hong Kong responded. The survey instrument captured demographic data on pet ownership history, species preferences, husbandry practices, and veterinary care utilization. The findings revealed a strong interest in pet reptiles, with lizards being particularly popular (67%) among new owners. Turtles remain common (35%), likely due to cultural factors and perceived ease of care. However, a gap was noted between the awareness and the implementation of proper husbandry practices, with 51% of respondents expressing concerns about enrichment and 21% uncertain about appropriate enclosure size. Veterinary care utilization also showed a disconnect, with 50% of the respondents reporting no regular check-ups were performed, despite acknowledging its importance. Reptile behavior served as a well-being indicator. Over 90% of the respondents observed normal behaviors like locomotion and breathing. Interestingly, a positive correlation emerged between reptile behavior scores and duration of ownership (r = 0.200, p < 0.01), suggesting improved well-being for reptiles that were in long-term care. These findings emphasize the need for educational initiatives promoting responsible pet ownership practices and fostering collaboration between reptile owners, veterinarians, and animal welfare organizations. By addressing these knowledge gaps and promoting a collaborative approach, our results aim to contribute to enhanced reptile welfare in the context of Hong Kong's evolving pet ownership trends.

Simple Summary: Nutritional secondary hyperparathyroidism in dogs arises from either a deficiency in vitamin D or an improper calcium-to-phosphorus ratio in their diet. This report covers four cases of large-breed puppies fed exclusively boneless, non-supplemented raw meat diets. These puppies exhibited severe pain and difficulty walking. Imaging studies, including radiographs and computed tomography scans, showed decreased bone density, and two of the puppies suffered pathological fractures, resulting in their euthanasia. The other two puppies recovered quickly after receiving pain relief and a balanced commercial diet. Nutritional secondary hyperparathyroidism is triggered by low levels of active vitamin D and calcium, causing elevated parathyroid hormone levels in the blood to correct mineral imbalances. This mechanism includes pulling calcium from the bones, making the bones weak and increasing fracture risk. Once uncommon due to balanced commercial dog foods, nutritional secondary hyperparathyroidism has reappeared with the trend of feeding raw meat diets. Timely diagnosis and treatment are vital for recovery, highlighting the necessity of balanced diets to prevent serious skeletal and neurological problems in developing puppies. Nutritional secondary hyperparathyroidism (NSH) in dogs is a condition that develops in response to a vitamin D deficiency or an imbalanced calcium-to-phosphorus ratio in dog food. Puppies of large-breed dogs exclusively fed a non-supplemented, boneless raw meat diet are especially susceptible to developing NSH due to their elevated calcium requirement. Reports on NSH in companion animals have been sparse in the last decades due to dog owners having easy access to commercially balanced dog foods. However, with the rising popularity of meat-based raw feeding, this condition has re-emerged. In this case series, four large-breed puppies fed exclusively non-supplemented, boneless raw meat diets presented with complaints of acute onset of pain and paresis. Radiographs and/or computed tomography (CT) scans showed reduced radio density of the skeleton in all four puppies. Two of the dogs had pathological fractures, and these two puppies were euthanized. One was subjected to a post mortem examination, which revealed cortical bone resorption and hypertrophy of the parathyroid glands. The remaining two puppies rapidly improved after receiving pain medication and a commercial, balanced diet. This case series demonstrates a risk of young dogs developing severe neurological deficits when fed a non-supplemented, boneless raw meat diet. [ABSTRACT FROM AUTHOR]

Simple Summary: Septic exudates in the body cavities of dogs and cats are considered a critical clinical condition. The current elective diagnostic tools for detecting septic effusion are bacterial culture and fluid cytology. Although culture is considered the gold standard, clinicians may not have access to the results for several days. This may result in a delayed diagnosis of septic effusion, which may have adverse effects on patient outcomes. This study compared the performances of cytology and bacterial culture in the identification of septic exudative body cavity effusions in dogs and cats. The results of our investigation indicated moderate agreement between cytology and microbiology. Cytology and bacterial culture results for exudative body cavity effusions in dogs and cats can be misleading when conducted individually. To improve diagnostic accuracy, these two methodologies should be integrated. The elective test for the determination of the effusions etiopathogenesis is represented by physico-chemical analysis and cytology. Nevertheless, the bacterial culture and antibiotic sensitivity tests are crucial for setting therapy and for the outcome. This study compared cytology with microbiology in the etiologic diagnosis of exudative body cavity effusions in dogs and cats collected from October 2018 to October 2022. All samples underwent aerobic and anaerobic culture and cytology examination. Bacterial identifications were confirmed using matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry, whereas cytological samples were blindly evaluated either in May Grunwald-Giemsa (MGG) or Gram-stained samples by two board-certified clinical pathologists. A moderate agreement (κ = 0.454) between cytology and bacterial culture was revealed. The sensitivity of the cytological evaluation in our study ranged from 38.5% to 67.9%, and the specificity ranged from 88.9% to 100%, depending on the type of the effusion, so cytology may not be representative of the etiopathogenesis, whereas bacterial culture can misidentify or fail to isolate the correct pathogen for difficult in vitro growing due to the presence of inhibitory substances or contamination. Cytology and bacterial culture results for exudative body cavity effusions in dogs and cats can be misleading if conducted separately, so these two tests should be performed together to increase diagnostic accuracy.

Simple Summary: Atresia Ani (AA) is a rare congenital anomaly affecting rectal and anal development in companion animals, with its occurrence in cats being poorly documented. This study investigated Type IV Atresia Ani (which includes a recto-vaginal fistula) in female cats, focusing on surgical intervention as the primary treatment. Over 2 years, nine female cats with Type IV Atresia Ani were analyzed for age, body condition, and fistula length. Statistical analysis revealed that a body condition score of 3, an age range of 3 to 4 weeks, and a fistula length of 1 to 2 mm influenced fecal incontinence and anal stenosis development during the perioperative period. Incidence of this condition was 4.7% among the 192 cats evaluated. Cats with a body condition score of 3, an age of 3 to 4 weeks, and a fistula size of 1 to 2 mm showed better surgical outcomes. This study is the first to report the disease incidence in cats undergoing surgery, according to the authors' knowledge. Atresia Ani (AA) is a rare congenital anomaly in companion animals affecting rectal and anal development. Its incidence in cats remains unreported. This retrospective study aimed to characterize age, body condition, fistula size, and perioperative outcomes in Type IV Atresia Ani (with recto-vaginal fistula) in female cats. Surgical intervention is the primary treatment. Conducted over 2 years, the study included nine female cats diagnosed with Type IV Atresia Ani and recto-vaginal fistula undergoing surgery. Statistical analysis used the R program (version 4.2.1) with Rstudio®® extension. Significant results were observed at a 95% confidence interval and p < 0.05. The condition had an incidence of 4.7% among the 192 cats evaluated over a 2-year period. The findings suggest that a body condition score of 3, an age of 3 to 4 weeks, and a fistula length of 1 to 2 mm correlated with better surgical outcomes, reducing the likelihood of fecal incontinence and anal stenosis development, and enhancing defecation awareness during the perioperative period. This study is the first to report the disease incidence in cats undergoing surgery, according to the authors' knowledge. [ABSTRACT FROM AUTHOR]

Simple Summary: Saccharomyces cerevisiae is a functional probiotic known to positively impact intestinal health in humans and other mammals. However, its effects on gut health in aged dogs have not been thoroughly studied. In our study, we investigate the effects of dietary Saccharomyces cerevisiae supplementation on the gut barrier, immune functions, antioxidant capacity, and gut microbiota profile in aged dogs. The results suggest that the addition of active Saccharomyces cerevisiae may improve the gut microbiota structure, enhance immune function, and increase the antioxidant capacity in aged dogs. The intestinal microbiome changes with age, influencing the host's health and immune status. Saccharomyces cerevisiae (S. cerevisiae) positively affects intestinal function in humans and animals, but its effects on gut health and the microbiota profile in aged dogs have not been thoroughly investigated. Twenty aged Labrador Retrievers were divided into two groups: a control group (CON) and a S. cerevisiae group (SC). The experiment lasted for 42 days, with assessments of their intestinal barrier function, inflammatory factors, antioxidant markers, and fecal microbiome composition. The results showed that dietary S. cerevisiae reduced the levels of TNF-α, IL-6, and IL-1β in the serum (p < 0.05). In the SC group, plasma superoxide dismutase and glutathione peroxidase activities increased, while the level of malondialdehyde significantly decreased (p < 0.05). Additionally, dietary S. cerevisiae lowered the serum zonulin and lipopolysaccharide (LPS) levels (p < 0.05) and inhibited fecal ammonia production (p < 0.05). Furthermore, the microbiota profile showed that dietary S. cerevisiae decreased the abundance of Firmicutes but increased the Chao index, the abundance of Bacteroidetes, and the proportion of Bacteroidetes to Firmicutes (p < 0.05). To conclude, dietary S. cerevisiae can regulate the gut's microbial structure and gut health, which may contribute to the overall health of companion animals as they age. [ABSTRACT FROM AUTHOR]

Simple Summary: Simple Summary: Anal sacs are paired skin invaginations present in most carnivores near the lateral margins of the anus and contain combined secretions of glands located in the anal sac wall. Anal sac disease is commonly seen in small animal practices, with a higher prevalence in dogs than in cats. The diagnosis of anal sac disease is usually based on the presentation of clinical signs and physical and rectal examination. However, the clinical signs are often non-specific and may be even absent, particularly in neoplastic cases. Ultrasonographic evaluation of anal sacs in dogs and cats is a practical, readily available, non-invasive, and low-cost modality and may enable the detection of anal sac disease at an early stage, even in asymptomatic patients. This study describes a presumed normal ultrasound morphology of anal sacs in dogs and cats, as well as the feasibility, advantages, and disadvantages of ultrasound screening of anal sacs in these companion animals. Ultrasonographic evaluation of canine and feline anal sacs is a practical promising modality to identify anal sac disease. However, limited data are available about normal ultrasound morphology of the anal sacs. This study describes the ultrasound morphology of presumed normal anal sacs in a larger sample of client-owned dogs and cats. A single-institutional prospective cross-sectional descriptive study was performed, and 137 dogs and 131 cats were included. The most common ultrasound features of the evaluated anal sacs in the dorsal plane were oval shape (99.3% of dogs and 98.5% of cats) and bilaterally similar content (94.2% of dogs and 95.4% of cats), mostly hypoechoic with diffusely hyperechoic points or unformed echogenic material (42.6% of dogs and 44% of cats). Gas in the lumen of the anal sac was detected in two dogs and mineralization in one dog. There was a statistically significant positive correlation between body weight and the size of anal sacs in dogs ≤15 kg and cats and a correlation between age and the size of anal sacs in cats. This simple method provides additional clinically significant information in detecting abnormal findings in asymptomatic patients and could contribute to the early detection of anal sac disease.

Simple Summary: The present research explored the links between human–pet relationship duration, pet life stage, and four markers of relationship quality: pet-related self-expansion, perceived pet responsiveness, perceived pet insensitivity, and human–animal bond, for dog and cat owners. Human–pet relationship duration negatively predicted self-expansion for dog and cat owners, and self-expansion was also higher for owners of younger pets compared to owners of older pets. Perceived pet responsiveness, perceived pet insensitivity, and human–animal bond were not associated with relationship duration or pet life stage. The findings of the present research indicate that human–pet relationship duration and pet life stage have implications for how much people feel a pet helps them grow. Although many companion animal (or "pet") owners report that their relationships with their pets are important, we know little about how animal ownership duration and animal life stage are related to relationship quality. In a sample of 1303 dog and cat owners, the present research explored the associations between relationship duration, pet life stage (puppy/kitten, young adult, mature adult, and senior), and four markers of relationship quality: pet-related self-expansion, perceived pet responsiveness, perceived pet insensitivity, and human–animal bond. We found that relationship duration was negatively and linearly associated with self-expansion for both dog and cat owners. Results comparing relationship quality markers across pet life stages revealed that for both dog and cat owners, self-expansion was higher for owners of younger animals compared to owners of older animals. There were no significant effects for perceived pet responsiveness, perceived pet insensitivity, or human–animal bond based on relationship duration or animal life stage. These findings indicate that the duration of the relationship with one's pet and animal life stage have implications for how much people feel a pet helps them grow, whereas other markers of human–pet relationship quality likely vary based on other experiences.

Simple Summary: This review explores the wide-ranging applications of Next-Generation Sequencing (NGS) techniques in veterinary medicine for companion animals. It addresses the need for advanced diagnostic and treatment approaches in veterinary care. The aims include understanding parasitic transmission, infectious disease dynamics, metabolic disorders, autoimmune diseases, oncological processes, and genetic predispositions in animals. The article demonstrates NGS's efficacy in comprehensive parasite profiling, rapid pathogen identification, personalized tumor analysis, and genetic disease elucidation. Conclusions highlight the transformative potential of NGS in enhancing veterinary diagnostics, treatment planning, and disease management for companion animals. The review's insights promise to revolutionize veterinary care, enabling precise and tailored treatments, improving animal health outcomes, and advancing overall societal well-being through healthier and happier companion animals. Next-Generation Sequencing (NGS) techniques have revolutionized veterinary medicine for cats and dogs, offering insights across various domains. In veterinary parasitology, NGS enables comprehensive profiling of parasite populations, aiding in understanding transmission dynamics and drug resistance mechanisms. In infectious diseases, NGS facilitates rapid pathogen identification, characterization of virulence factors, and tracking of outbreaks. Moreover, NGS sheds light on metabolic processes by elucidating gene expression patterns and metabolic pathways, essential for diagnosing metabolic disorders and designing tailored treatments. In autoimmune diseases, NGS helps identify genetic predispositions and molecular mechanisms underlying immune dysregulation. Veterinary oncology benefits from NGS through personalized tumor profiling, mutation analysis, and identification of therapeutic targets, fostering precision medicine approaches. Additionally, NGS plays a pivotal role in veterinary genetics, unraveling the genetic basis of inherited diseases and facilitating breeding programs for healthier animals. Physiological investigations leverage NGS to explore complex biological systems, unraveling gene–environment interactions and molecular pathways governing health and disease. Application of NGS in treatment planning enhances precision and efficacy by enabling personalized therapeutic strategies tailored to individual animals and their diseases, ultimately advancing veterinary care for companion animals.

Simple Summary: Hearing Dogs are assistance animals who provide practical help to their owners with hearing loss/Deafness by alerting them to environmental sounds. While some studies have verified the contribution of Hearing Dogs to their owners' quality of life, little is known about the relationship that is established between canine and owner. This survey study investigated the anticipated role of Hearing Dogs in 23 prospective owners, as well as emotional attachment in 58 Hearing Dog owners. Results revealed that prospective owners expected the dog to play a broad supportive role in their lives, beyond simple assistance with sounds. For owners, a strong emotional component was evident in their relationships with the Hearing Dogs, particularly in the "people substitution" category. This study suggests that the relationship expectations of potential Hearing Dog recipients should be achievable, as evidenced by the strong relationships reported by owners. The reported positive outcomes of animal-assisted services have led to an emerging interest in many different aspects of human–animal interactions. The influence of an assistance animal is thought to encompass several psychosocial domains in the life of a person with a significant health impairment. However, little is known about the mechanisms underlying the relationship between Hearing Dogs and their owners. A prospective study design using a written questionnaire method was utilized to survey 58 current and 23 prospective Australian Lions Hearing Dogs owners. The Pet Expectations Inventory (PEI) was used to investigate the anticipated role of Hearing Dogs in waitlisted persons with hearing loss/Deafness, whereas the Lexington Attachment to Pets Scale (LAPS) was completed by current owners to assess emotional attachment. The results revealed a high mean PEI score (M = 73.1, SD = 10.9, Mdn = 73.0, range: 55–91), with prospective owners strongly expecting the role of Hearing Dogs to include companionship/love and security. Furthermore, strong attachment features were evident in the owners' relationships with Hearing Dogs, as demonstrated by a high total LAPS score (M = 81.2, SD = 7.5, range: 63–91). Mean scores for statements within the "people substitution" category were highest (range = 3.6/4.00–3.9/4.00). In this demographically homogenous study cohort, it appeared that the high expectations of potential Hearing Dog owners for their animals to serve supportive roles beyond hearing assistance should be achievable, as evidenced by the strong attachment relationships displayed between Hearing Dogs and their owners.

Simple Summary: Rodents have become increasingly popular as household pets, but few studies have focused on tumors in pet rodents. Pet rodents differ from their laboratory counterparts in many aspects such as geographical preference of pet species or breeds, household raising conditions, population density, and life expectancy. Therefore, it is worth conducting this pathological study of 77 spontaneous tumors from 70 pet rodents. Overall, mammary gland tumors were common. In the meantime, mouse mammary tumor virus (MMTV)-like sequences were found in the tissues of dogs, cats, and humans, raising the concern of whether these pets may incidentally serve as a vehicle for the cross-species transmission of MMTV to household personnel. For that purpose, nuclei acid extracted from the formalin-fixed paraffine-embedded tissues of 20 rodent mammary gland tumors was detected for MMTV env gene sequences. All tumors revealed negative results of MMTV detection. Compared to the number of studies on the neoplasms of laboratory rodents, fewer studies have focused on spontaneous neoplasms in pet rodents. Notably, the mouse mammary tumor virus (MMTV) is associated with mammary tumors in rodents. In this study, 77 tumors and tumor-like lesions of biopsy samples were collected from 70 pet rodents, including hamsters (n = 47), guinea pigs (n = 16), unknown species (n = 4), rats (n = 2), and a gerbil. Fifty tumors were collected from 47 hamsters, in which the most common tumors were mammary tumors (13/50), followed by fibrosarcoma (9/50), mast cell tumors (4/50), and squamous cell carcinoma (4/50). The collected subtypes of mammary tumors in hamsters included tubular carcinoma (n = 5), tubular adenoma (n = 4), carcinoma and malignant myoepithelioma (n = 1), simple tubular carcinoma (n = 1), adenosquamous carcinoma (n = 1), and tubulopapillary adenoma (n = 1). In addition, twenty tumors were collected from guinea pigs, in which the most common tumor was lipoma (6/20), followed by adenocarcinoma of the mammary gland (4/20), trichofolliculoma (2/20), and collagenous hamartomas (2/20). In guinea pigs, the subtypes of mammary gland tumors were tubular carcinoma (n = 2), tubular and solid carcinoma (n = 1), and tubulopapillary carcinoma (n = 1). In 20 cases of mammary tumors, MMTV was not detected, implicating no evidence of MMTV infection in mammary oncogenesis in pet rodents in Taiwan. [ABSTRACT FROM AUTHOR]

Simple Summary: Access to veterinary care for pet owners is an important part of keeping animals healthy. Not having enough money and other resources can make it hard for pet owners to get veterinary care. Recently, veterinarians have started offering a range of care options to address clients' needs. But veterinarians still mainly give the most technological and specialized care they learned in their training. The goal of this study was to learn more about veterinarians' behaviors, knowledge, attitudes, and beliefs about offering more treatments in a range from less to more sophisticated. This study found that many veterinarians do report offering a range, but that it is mostly the veterinarians who feel the most comfortable and confident doing it. When veterinarians had been in practice for more than 20 years, they were less likely to offer a range of services. Rural veterinarians were more likely to offer a range than urban veterinarians. These results offer a reference for more exploration into what veterinarians report about offering a range of care options to people who need help. Access to veterinary care for animal owners is an important part of keeping animals healthy and keeping pets and people together whenever that is appropriate. Insufficient financial and other resources to allocate to veterinary care are major barriers for pet owners to receiving preventative, sick, and emergency services. The veterinary community has begun to incorporate offering a range of diagnostic and treatment options more intentionally in response to clients' inability to pay and to a lesser extent to mitigate other barriers to care. Many veterinarians are nonetheless oriented toward providing specialized and more sophisticated care based on their training. This study sought to identify the self-reported behaviors, knowledge, attitudes, and beliefs of veterinarians about offering a spectrum of care options (SoC) to clients. The finding that many reported offering SoC is encouraging. However, veterinarians who report comfort and confidence in a variety of aspects of clinical care were most likely to offer SoC. Practitioners in the field for 20 or more years were less likely to offer SoC to clients with financial limitations. Rural veterinarians were more likely to offer SoC to any client compared to urban veterinarians. These results provide a point of reference and potential focus for veterinarians who are not currently offering SoC as well as an exploration of veterinarians' reported knowledge, behaviors, attitudes, perceptions, and concerns about SoC.

Simple Summary: This research looks at how people acquire their dogs, how dogs leave their homes, and how both relate to household income. A survey of 6318 participants in seven distinct communities across the US asked respondents how they acquired their current dogs, how previous dogs left their household, where they left to, and what their income is. We found that, the lower the income, the more likely people obtained their dog through friends and family, while the opposite was true for buying or adopting a dog. At the same time, people in lower-income categories were more likely to give away a dog to friends and family versus to an animal shelter. This means lower-income communities rely more on their friends and family for acquiring and placing their dogs, and we suggest that animal shelters should support these people and their pets to help them stay with those caring for them, rather than solely seeing them as potential adopters. This research examines the ways people acquire dogs in the US as well as the ways the dogs leave the household and the way these differ by income level in seven geographically diverse study communities. A web-based panel survey was distributed and received 6318 responses. Individuals were asked a series of demographic and socioeconomic questions as well as how they acquired their current dogs, how previous dogs left their household, and where they left to. The results indicate that the likelihood of acquiring a dog through friends and family decreased monotonically as income increased, while the opposite was observed for adopting and purchasing a dog. The likelihood of giving a dog away to a friend or family member also decreased as income increased, as opposed to shelter surrender—a person earning over USD 100,000 annually was more than four times likelier to surrender to a shelter than a person earning under USD 15,000. The results suggest a stronger reliance on informal social networks in lower-income communities for both obtaining and placing dogs. As these dogs would otherwise end up in the shelter system, animal shelters may support low-income pet owners to help keep their dogs within their community of care. [ABSTRACT FROM AUTHOR]

Simple Summary: The search for alternative treatments is necessary for diseases where conventional therapies are ineffective. In recent years, therapies using mesenchymal stem cells have emerged as one of the most appropriate alternatives in regenerative medicine. Therapy with these types of cells is progressively increasing as a therapeutic option in veterinary medicine, leading to significant advances in treating certain pathologies. This review summarizes the current knowledge on mesenchymal stem cell therapies and their potential therapeutic and clinical effects on wound and skin, ocular, and neuromuscular diseases in dogs and cats. Mesenchymal stem cells (MSCs) are considered a very promising alternative tool in cell therapies and regenerative medicine due to their ease of obtaining from various tissues and their ability to differentiate into different cell types. This manuscript provides a review of current knowledge on the use of MSC-based therapies as an alternative for certain common pathologies in dogs and cats where conventional treatments are ineffective. The aim of this review is to assist clinical veterinarians in making decisions about the suitability of each protocol from a clinical perspective, rather than focusing solely on research. MSC-based therapies have shown promising results in certain pathologies, such as spinal cord injuries, wounds, and skin and eye diseases. However, the effectiveness of these cell therapies can be influenced by a wide array of factors, leading to varying outcomes. Future research will focus on designing protocols and methodologies that allow more precise and effective MSC treatments for each case. [ABSTRACT FROM AUTHOR]

Simple Summary: In spite of significant reductions in the numbers of animals entering shelters and being killed there over the last decades, the beliefs that companion animals must be under the direct control of a human guardian, and that capturing and often killing animals is morally justifiable and even necessary, continue to guide animal sheltering practices in the United States. Looking at the historical origins of animal control and sheltering in the US reveals a high level of consistency in ideologies and practices across almost 150 years. In this commentary, two scholars on animal sheltering in the US examine the historical legacies of animal control and sheltering in the US to show how they are problematic and dysfunctional and need to be abandoned to improve the lives of companion animals and the human communities of which they are a part. This paper examines the legacies of the emergence of the animal control and sheltering industry in the United States and their impact on contemporary public animal shelters. While decades of gradual reform have helped substantially reduce the number of animals entering shelters and being killed there, contemporary animal sheltering largely continues to follow the path set when animal sheltering developed in the late 1800s and early 1900s. Three key interrelated legacies of the pound model of early animal control and sheltering enduringly shape sheltering today: (1) the institutional culture of animal shelters grounded in the logics of caging and killing; (2) the lack of visibility and transparency, especially within government shelters; and (3) the economic logics of the pound model, including the disparities in sheltering resources across communities. Examining the origins of animal control and sheltering and identifying the specific legacies of this pound model within contemporary government-funded shelters improves understanding of why such shelters in the US have developed with a particular set of practices and ideologies, and thus provides an important footing for envisioning and enacting radical changes in animal sheltering.

Simple Summary: Vitamin A, a vital fat-soluble micronutrient, is indispensable for the health and well-being of companion animals, notably dogs and cats. Its multifaceted roles encompass crucial functions in vision, immune modulation, and reproductive health. Vitamin A is intricately involved in cellular differentiation, gene expression, and antioxidant defense mechanisms, exerting a profound influence on the overall physiological function. A deficiency in this essential vitamin can lead to a spectrum of health issues, including compromised vision, an impaired immune function, and reproductive abnormalities. A comprehensive understanding of the mechanisms involved in the absorption, cellular uptake, and metabolic pathways of vitamin A is crucial for optimizing the nutrition of companion animals. Further research on retinoids is essential to deepen our understanding and to refine dietary recommendations tailored to the unique needs of companion animals, thereby ensuring their optimal health and vitality. The health of companion animals, particularly dogs and cats, is significantly influenced by nutrition, with vitamins playing a crucial role. Vitamin A, in particular, is indispensable, with diverse roles ranging from vision to immune modulation and reproduction. Despite its importance, the metabolism and dietary requirements of vitamin A in companion animals remain complex and not fully understood. This review provides a comprehensive overview of the historical perspective, the digestion, the metabolism, the physiological roles, the deficiency, the excess, and the interactions with other micronutrients of vitamin A in companion animals. Additionally, it highlights future research directions and gaps in our understanding. Insights into the metabolism of vitamin A in companion animals, personalized nutrition strategies based on genetic variability, longitudinal studies tracking the status of vitamin A, and investigations into its immunomodulatory effects are crucial for optimizing pet health and wellness. Furthermore, understanding the stability and bioavailability of vitamin A in pet food formulations is essential for ensuring the provision of adequate micronutrients. Overall, this review underscores the importance of vitamin A in companion animal nutrition and the need for further research to enhance our understanding and to optimize dietary recommendations for pet health and well-being.

Simple Summary: Oclacitinib is a tablet-based therapy given for itching that is caused by allergic or atopic dermatitis in dogs. The objective of this study was to understand pet owners' perceptions of the conventional film-coated form of oclacitinib and the chewable form of oclacitinib in terms of convenience and value. Firstly, an interview phase with pet owners and veterinarians was used to develop detailed written profiles of these treatment options. Then, pet owners were invited to participate in a survey about their experiences and preferences. Overall, 1590 pet owners provided survey responses. Most respondents (62%) reported having experienced challenges giving tablet-based therapies to their dog(s), and half of the respondents (52%) had experience giving flavoured or chewable tablets to their dog. Comparing oclacitinib and chewable oclacitinib (with or without associated costs), the majority of the respondents preferred the chewable formulation in all countries for both short-term and long-term itch (≥58%; all p < 0.05). Chewable and/or palatable treatment options may be welcomed by pet owners and may have potential positive impacts on convenience, compliance, outcomes, quality of life, and the human–animal bond. Oclacitinib is an oral therapy indicated for pruritus associated with allergic or atopic dermatitis in dogs. This study sought to assess pet owners' perceptions of the relative convenience and value of the conventional film-coated formulation and the chewable formulation. A quantitative discrete-choice experimental methodology was applied, comparing (conventional, film-coated) oclacitinib versus chewable oclacitinib using unbranded treatment profiles. Initially, a qualitative interview phase with pet owners and veterinarians was conducted to develop detailed treatment profiles. Subsequently, pet owners participated in a quantitative survey. Overall, 1590 pet owners provided survey responses. Most respondents (62%) reported having experienced challenges administering tablet-based therapies to their dog(s). Half of all respondents (52%) had experience administering flavoured or chewable tablets to their dog. Comparing oclacitinib and chewable oclacitinib (with or without associated costs), the majority of the respondents preferred the chewable formulation in all regions across short-term and long-term scenarios (≥58%; all p < 0.05). The current research is one of few survey-driven studies for treatment preferences in companion animal medicine. Veterinarians may offer chewable or palatable treatment options where available, with potential positive impacts on convenience, compliance, outcomes, quality of life, and the human–animal bond.

Simple Summary: In practical terms, pet owners' lack of awareness regarding weight reduction protocols, coupled with the high costs of commercial prescription diets, often makes it difficult for them to adhere to such programs in the long term. This study addressed the costs of weight loss per kilogram of metabolic weight in dogs and cats, considering various dietary regimens. The weight reduction protocol, supervised by veterinarians, involved eight dogs and ten cats. The results indicated that the monthly and total cost per kilogram of metabolic weight was significantly lower when using commercial dry foods compared to homemade diets (p < 0.001), reducing costs by 40.88% and 41.01% for dogs and cats, respectively. Despite owners' lack of awareness and associated costs, it is concluded that commercial prescription diets offer greater financial benefit for pet weight reduction protocols, emphasizing the importance of considering economic factors when implementing weight control strategies. These findings underscore the economic challenges associated to pet weight loss and emphasize the necessity for cost-effective solutions to promote sustained owner compliance. In the context of the rising prevalence of obesity among pets, this study aimed to assess the economic aspects of weight reduction protocols for dogs and cats, considering the lack of information and the varying costs of commercial and homemade diets. The results indicated an average weekly weight loss rate of 1.02% for dogs and 0.92% for cats, with a reduction in body fat mass (p < 0.005). The cost analysis included an evaluation of both dry and wet commercial prescription diets as well as homemade diets. The results unveiled higher expenses associated to wet commercial diets, followed by homemade and dry commercial diets (p < 0.001). The study demonstrated that despite the initial investment, the long-term benefits of weight loss, including improved health and reduced financial burdens for owners, justify the expenses incurred. This comprehensive analysis provides veterinarians and pet owners with valuable insights into the economic considerations of weight reduction protocols, facilitating informed decision making and promoting pet well-being.

Simple Summary: Chronic kidney disease (CKD) is a vital issue waiting to be solved in the feline population. The efficacy of probiotics to prevent/alleviate CKD has been widely investigated in animal models. This pilot study combined a renal-protective functional Lactobacillus mixture (Lm) with pet feed as probiotic pet treats. CKD cats (stages 2 and 3) showed that kidney function and life quality were improved through modifying the composition of gut microbiota and metabolic patterns after administrating Lm pet treats daily for 8 weeks. This study clarified the possible mechanism of Lm in CKD cats and provided a possible novel way to treat cats with probiotics. Microbiota-based strategies are a novel auxiliary therapeutic and preventative way of moderating chronic kidney disease (CKD). Lactobacillus mixture (Lm) was previously demonstrated to exert a renal-protective function in the CKD mice model. The efficacy of probiotics in pet foods is a relatively new area of study, and thus verifying the potential health benefits is necessary. This study evaluated the efficacy of Lm treats in feline CKD and elucidated the mechanisms underlying host-microbe interactions. CKD cats (2 and 3 stages) were administrated probiotic pet treats daily (10 g) for 8 weeks. The results demonstrated that during the eight weeks of Lm administration, creatinine was reduced or maintained in all cats with CKD. Similarly, gut-derived uremic toxin (GDUT), indoxyl sulfate (IS), were potential clinical significance in IS after Lm treatment (confidence intervals = 90%). The life quality of the cats also improved. Feline gut microbiome data, metabolic functional pathway, and renal function indicator analyses revealed the possible mechanisms involved in modulating CKD feline microbial composition. Further regulation of the microbial functions in amino acid metabolism after Lm administration contributed to downregulating deleterious GDUTs. The current study provides potential adjuvant therapeutic insights into probiotic pet foods or treats for pets with CKD. [ABSTRACT FROM AUTHOR]

Simple Summary: Animal charities want to teach people about what animals need and often run campaigns to achieve this. These campaigns usually focus on different aspects of animal welfare. In March 2019, the Royal Society for the Prevention of Cruelty to Animals (RSPCA) launched a campaign called #DogKind. It aimed to increase awareness of dog owners to identify separation-related behaviours in dogs and encourage owners to seek help from reliable sources. To evaluate the campaign's effectiveness, we asked people a series of questions before and after the campaign. We also tested whether adding a video to the website's information made any difference to the campaign's effectiveness. This study found that the campaign successfully reached its target audience of 25–34-year-olds but did not help dog owners become more aware of separation-related behaviours or increase the number of owners intending to seek help from reliable sources. Additionally, showing a video as part of the campaign did not improve its effectiveness. This study shows that this campaign had limited success in achieving its targets and highlights the importance of thorough evaluations of campaigns as educational interventions. One of the main aims of companion animal welfare charities is to educate the public about the needs of animals. This is frequently performed through campaigns focusing on specific aspects of welfare. The Royal Society for the Prevention of Cruelty to Animals (RSPCA), Britain's biggest animal welfare charity, launched the nationwide #DogKind campaign in March 2019. Targeted mainly at 25–34-year-olds, the campaign aimed to increase awareness of separation-related behaviour (SRB) among dog owners and encourage them to seek help for SRB from reliable sources. This research involved a quasi-experimental, non-equivalent control group design evaluating the campaign's effectiveness. It was conducted through a series of online surveys at three different time points: before the launch of the campaign (n = 2002), six months after (n = 2423), and, again, two months later (n = 269), during which we asked the same questions regarding knowledge of SRB. An experimental trial of 269 participants tested whether accessing a video alongside the campaign web pages increased the effectiveness of the campaign objectives. Overall, the campaign appeared to be effective in reaching its target audience but not at raising awareness of SRB or increasing the number of owners intending to seek help. The inclusion of a video in the campaign made no difference to its effectiveness. This study shows that this campaign had limited success in achieving its targets and highlights the importance of thorough evaluations of education interventions that aim to improve the welfare of companion animals.

Simple Summary: The purpose of this study is to evaluate veterinary records of fish diagnosed with cancer to determine the most common presentation of this disease and the efficacy of various treatments. Currently, there are no comprehensive analyses of cancer across all fish species, and this study serves to aid veterinary clinicians in the management of these patients. Fish serve an important role in society as companion animals, educational ambassadors, and research models, and advances in their standard of care benefit veterinary medicine and several other industries. This study evaluated neoplasia in fish using medical records from zoos, aquariums, and exotic animal veterinarians. The parameters evaluated included geographic location, habitat type, signalment, anatomic location of neoplasia, type of neoplasia as confirmed with histologic examination, survival time, and treatments provided for each patient. These data were entered into the Exotic Species Cancer Research Alliance (ESCRA) database. Out of 455 cases from across the United States and England, most animals submitted were from zoologic parks or aquariums (62.9%), followed by private ownership (1.5%). The percent of female (19.3%) and male (17.8%) patients were similar, and the mean age at the time of diagnosis was 99.45 months, with a range of 12 to 300 months. The species with the highest neoplasia prevalence was koi (18.5%), followed by goldfish (10.8%). The eye was the most commonly reported site for a primary neoplasm (8.4%), and the most prevalent diagnosis across all organ systems was soft tissue sarcoma (26.2%). Only 13 patients in this study (2.9%) received any form of treatment, with a mean survival time of 8.85 months post-treatment. These data demonstrate that while information related to clinical therapy of cancer in fish species is lacking, surgical excision of tumors in fish, when feasible for the patient and client, may improve patient outcomes.

Simple Summary: Past research regarding the impact of companion animals on well-being has yielded variable results, with some studies finding that companion animals have a positive impact on mental well-being and others finding neutral or negative impacts. This study explored potential causes for these contradictory results, measuring the relationship science concepts of attachment, self-expansion, perceived responsiveness, and perceived insensitivity within the human–companion animal relationship, as well as mental health outcomes of depression, anxiety, and affect; and loneliness as a mediator between the relationship science concepts and the mental health outcomes. Attachment, self-expansion, and perceived pet insensitivity all significantly predicted at least one mental health outcome. We also found that loneliness mediates the relationship between attachment, self-expansion, and perceived pet insensitivity, and all of the mental health outcomes. Our results indicate that these relationship dimensions play a role in the well-being benefits derived from having a companion animal. Research into the impact of companion animals on well-being has been both extensive and inconclusive, with studies finding both positive and negative relationships. The present research explored three previously unexamined relationship science concepts that may help clarify whether companion animals provide well-being benefits: self-expansion (the process of adding positive content to the self through incorporating new resources and perspectives into one's identity or engaging in novel, exciting activities), perceived pet responsiveness, and perceived pet insensitivity; as well as attachment. We focused on dog and cat owners' depression, anxiety, positive and negative affect, and loneliness through an online survey with a large sample population (N = 1359). We found that perceived pet insensitivity is a significant positive predictor of depression, anxiety, negative affect, and loneliness; that attachment is a significant positive predictor of depression, anxiety, and loneliness, and a significant negative predictor of positive affect; and that self-expansion is a significant positive predictor of positive affect, and a significant negative predictor of loneliness. Loneliness emerged as a mediator in the relationship between perceived pet insensitivity, attachment, self-expansion, and all mental well-being outcome variables. These findings indicate that perceived pet insensitivity, attachment, and self-expansion may play an important yet neglected role in well-being outcomes. [ABSTRACT FROM AUTHOR]

Simple Summary: The escape of pets plays a significant role in the establishment of invasive species. In Japan, where most pet birds in households are foreign-origin species, one study examined the number of these birds that escaped into the wild. Information on pet bird escapes was gathered from online lost-and-found websites for pets between 2018 and 2021. Escape incidents occur daily, with Budgerigars and Cockatiels being the most common escapees. Despite being popular pets worldwide, these birds rarely establish themselves outside their natural habitats. Monk Parakeets, which briefly bred in the wild in Japan in the 1980s but failed to establish themselves, and the Rose-ringed Parakeet, already established as an invasive species in the Kanto region, have also occasionally been reported as escapees. Considering their global invasive presence, it is crucial to be vigilant in preventing pet birds from escaping to protect local ecosystems. Regular escape from commonly maintained species highlights the need for responsible pet ownership and heightened awareness to curb potential environmental impacts. The escape of pet birds into the wild raises concerns about the introduction of invasive avian species. This study investigated the impact of escaped pet birds on the introduction of non-native species in Japan. Data sourced from four lost-and-found pet websites between January 2018 and December 2021 revealed 12,125 recorded escapes exhibiting both daily occurrences and seasonal fluctuations. Statistical modeling identified the monthly average temperature (positively correlated) and maximum electricity demand (negatively correlated) as influential factors. Text analysis revealed "window" and "open" as frequently cited reasons for escapes. Budgerigars (Melopsittacus undulatus) and Cockatiels (Nymphicus hollandicus) accounted for 76% of the total escape, suggesting a low perceived risk of establishment in nonnative environments. Interestingly, two globally established invasive species, the Rose-ringed Parakeet (Psittacula krameri) and Monk Parakeet (Myiopsitta monachus), were among the escaped birds. While the Rose-ringed Parakeet is locally naturalized in Tokyo and its adjacent prefectures, the Monk Parakeet failed to establish itself in Japan. Despite the limited number of escaped Monk Parakeets, ongoing efforts are crucial for preventing the potential re-establishment of species with such capabilities. [ABSTRACT FROM AUTHOR]

Simple Summary: Obesity is a significant health concern among companion animals, particularly dogs and cats, with numerous detrimental health implications. Many pet owners struggle with managing their pets' weight, and they often underestimate their pets' body condition. This study, held in France from 2020 to 2022, revealed that about one quarter of pet owners underestimate their pets' body condition. Having children was linked to this underestimation for both dog and cat owners. This discovery highlights the importance of taking a comprehensive approach to the health and well-being of pets and emphasizes the need for a holistic "One Health" strategy. Managing pet obesity relies heavily on the active involvement of owners; however, a key challenge arises from misperceptions about their own pet's body condition. Given evolving societal dynamics like the body positivity movement, understanding owners' perceptions is increasingly pivotal. To evaluate the differences in owners' perception, this study compared the use of verbal and visual body condition score scales versus the established nine-point body condition score system. The factors linked to underestimation were further specifically investigated. Owners of healthy adult dogs and cats attending vaccination consultations in Veterinary Hospitals in France between 2020 and 2022 were recruited. They were required to assess their pets' body condition initially using an oral description and then with the nine-point BCS visual scale. Their assessments were then compared with the BCS determined by veterinary health care personnel, considered the primary investigator. A total of 304 dogs and 270 cats were included in the study. It was observed that 27% of dog owners and 24% of cat owners underestimated their pets' body condition. Among dog and cat owners, factors associated with the underestimation of body condition were the pets' overweight status and having children. This discovery emphasizes the need for a holistic One Health approach that prioritizes the health and well-being of both humans and their pets. When it comes to pet owners evaluating their pets' body condition, underestimation proved to be the predominant misperception. Addressing this issue requires comprehensive education to empower owners to recognize and comprehend their pets' overweight status, a critical step for the overall well-being of companion animals.

Simple Summary: People can develop meaningful relationships with companion animals, and they behave towards them in specific ways. For example, they spend time together in close proximity, apologize or talk to them as if they are human, and experience social support from their pets. This study aims to explain these types of interactions in a sample of cat owners and dog owners in the Netherlands. The more pet owners rated the mental abilities of their pet to be similar to those of humans (anthropomorphization), the more they displayed making-up behavior towards their pet, and the stronger they experienced social support from their pet. However, to engage in communication behavior (e.g., petting, kissing, talking) it is not necessary to anthropomorphize the pet. Dog owners anthropomorphize more than cat owners; this might be due to a higher symmetry in social behaviors between humans and dogs. Lastly, the social role of the pet (partly) mediates the association between anthropomorphization and owner behaviors and experience of social support. This mediation effect is more pronounced in cat owners compared to dog owners. Background: For sustainable and healthy relationships with pets, attributing some degree of human abilities to the pet (anthropomorphization) might be necessary. We hypothesize that the tendency to anthropomorphize pet animals is related to relationship behaviors (communication and making up) and the experience of social support. Perceiving the pet in a human social role (e.g., family member or friend) might mediate this relationship. Method: Associations were tested in a mixed sample of cat and dog owners by means of multiple linear regression, moderation, and (moderated) mediation analyses. The differences between cat and dog owners were examined with pet type as the moderator in a moderated mediation analysis. Results: Dog owners anthropomorphize their pets more than cat owners. The social role of the pet mediates the association between anthropomorphization and relationship behavior and social support. The mediation effects were stronger for cat owners than for dog owners. Moreover, our newly developed comparative anthropomorphism measure was a better predictor than the commonly used general anthropomorphism measure (IDAQ). [ABSTRACT FROM AUTHOR]

Simple Summary: With the global spread of COVID-19, surveillance of companion animals living in close proximity to humans has been conducted due to the zoonotic nature of the causative agent, SARS-CoV-2. However, further research is still needed when it comes to livestock animals, particularly cattle and goats that are raised in grazing management systems as part of a group. In this study, nasal swabs and blood samples were collected from randomly selected Korean native cattle and Korean native black goats across nine different provinces in Korea. Of the 1798 animals tested, we found 1 cattle and 1 goat with detectable SARS-CoV-2 RNA, 54 Korean native cattle (4.60%) and 16 Korean native black goats (2.56%) with antibodies, and 51 Korean native cattle (4.34%) and 14 goats (2.24%) with virus-neutralizing antibodies. Infections have been found in various animals after initiating in wildlife and spreading widely among humans, and our results indicate the presence of antigens and antibodies in Korean native cattle and Korean native black goats. This suggests a potential reverse zoonosis, where humans may be infected through a widespread epidemic. Therefore, continuous monitoring is crucial, and additional testing should be conducted on a broader range of animals. The COVID-19 pandemic is caused by the zoonotic SARS-CoV-2 virus. A wide range of animals that interact with humans have been investigated to identify potential infections. As the extent of infection became more apparent, extensive animal monitoring became necessary to assess their susceptibility. This study analyzed nasal swabs and blood samples collected from randomly selected Korean native cattle and Korean native black goats. The tests conducted included real-time qPCR to detect SARS-CoV-2 antigens, an ELISA to detect antibodies, and a plaque reduction neutralization test (PRNT) to determine the presence of neutralizing antibodies. Among the 1798 animals tested (consisting of 1174 Korean native cattle and 624 Korean native black goats), SARS-CoV-2 viral RNA was detected in one Korean native cattle and one Korean native black goat. ELISA testing revealed positive results for antibodies in 54 Korean native cattle (4.60%) and 16 Korean native black goats (2.56%), while PRNTs yielded positive results in 51 Korean native cattle (4.34%) and 14 Korean native black goats (2.24%). The presence of SARS-CoV-2 antigens and/or antibodies was identified in animals on farms where farmworkers were already infected. It is challenging to completely rule out the possibility of reverse zoonotic transmission from humans to livestock in Korea, although the transmission is not to the same extent as it is in highly susceptible animal species like minks, cats, and dogs. This is due to the limited geographical area and the dense, intensive farming practices implemented in these regions. In conclusion, continuous viral circulation between humans and animals is inevitable, necessitating ongoing animal monitoring to ensure public health and safety. [ABSTRACT FROM AUTHOR]

Simple Summary: Cryptosporidium spp. and Giardia duodenalis, enteric protozoan pathogens affecting humans and animals, elicit substantial global public concern. This study conducted in Taiwan sought to determine the prevalence and co-infection rates of Cryptosporidium spp. and G. duodenalis in dogs and cats. The investigation encompassed an analysis of infection rates and associated risk factors within the surveyed population. Predominantly identified species were C. canis and C. felis, aligning with canine-specific assemblages C and D. In contrast, the infrequent presence of human-specific assemblage A was noted in Giardia-positive samples. Phylogenetic analysis alluded to the potential for zoonotic transmission originating from domesticated animals. This underscores the role of pets as possible reservoirs for the transmission of cryptosporidiosis and giardiasis to humans in Taiwan. Cryptosporidium spp. and Giardia duodenalis are enteric protozoan pathogens in humans. and animals. Companion animals infected with zoonotic species/assemblages are a matter of major public concern around the world. The objectives of the present study were to determine the prevalences of Cryptosporidium spp. and G. duodenalis infections and their co-infection statuses in dogs and cats living in Taiwan and to identify the species and assemblages. Fecal samples were collected from local animal shelters (n = 285) and a veterinary hospital (n = 108). Nested polymerase chain reaction (PCR) was performed using the SSU-rRNA, β-giardin, and glutamate dehydrogenase genes for Cryptosporidium spp. and G. duodenalis, respectively. Results showed that the overall prevalences of Cryptosporidium and G. duodenalis were 7.38% (29/393) and 10.69% (42/393). In addition, co-infection was detected in 1.02% (4/393) of all samples. Sample source, clinical sign, and breed may be risk factors that influence the infection rate. In Cryptosporidium-positive samples, C. canis and C. felis were detected most frequently. Although the canine-specific assemblages C and D (37/42) were dominant, the zoonotic human-specific assemblage A (1/42) was also found in Giardia-positive samples. Phylogenetic analysis revealed that most positive samples belonged to host-specific subtypes/assemblages, while some Cryptosporidium or Giardia-positive samples could be zoonotic. The findings suggested that pet animals could be a cause of zoonotic transmission, causing human cryptosporidiosis and giardiasis in Taiwan. [ABSTRACT FROM AUTHOR]

Simple Summary: More than 110,000 companion animals go to shelters yearly due to abandonment in Republic of Korea. Veterinary costs have been blamed for the abandonment of these animals above the reported leading causes of the socioeconomic status of their owners, cost and behavior issues of animals, or housing restrictions, though without supporting evidence. This study examined whether veterinary costs and socioeconomic factors are, in fact, related to animal abandonment in 128 regions of Republic of Korea in 2020 and 2021 through a statistical analysis. Five predictors (two veterinary cost data and three socioeconomic factors) could explain one-third of animals abandoned in 2020. The same five predictors could also explain one-third of animals abandoned in 2021. These results can be used in future discussions about developing policies to reduce animal abandonment in Republic of Korea. More than 110,000 companion animals are sent to shelters each year due to abandonment in Republic of Korea, and there is a need to analyze the causes of the relinquishment of animals and implement appropriate policies. Veterinary costs have been blamed for this issue in Republic of Korea above the reported leading causes of socioeconomic status of owners, cost and behavior issues of the animals, or housing restrictions. However, it is rare to find supporting evidence. In this study, we aimed to determine whether veterinary costs and socioeconomic factors are related to animal relinquishment in Republic of Korea. Multiple regression models were used to test if veterinary costs and socioeconomic indicators can account for relinquishment in 128 regions of Republic of Korea in 2020 and 2021. When five independent variables (two veterinary cost data and three socioeconomic indicators) were included, the regression model showed significance in explaining pet relinquishment in 2020, with an adjusted coefficient of determination of 0.3956. Pet relinquishment can also be explained by the same five variables for 2021, with an adjusted coefficient of determination of 0.391 with p < 0.0001. The findings suggest that intervention to reduce companion animal relinquishment in Republic of Korea should focus on lightening the financial burdens of owners as the socioeconomic status of a community worsens.

Simple Summary: This study compares the gut microbiomes of healthy domestic ferrets and cats, which are both carnivorous pets. While ferrets have a population of around 500,000 in the United States, little is known about their gut bacteria. We collected stool samples from 36 healthy ferrets and 36 healthy cats and analyzed their bacterial DNA. We found that the ferrets had more Firmicutes and Proteobacteria, whereas the cats had higher levels of Bacteroidota and Actinomycetota. The ferret microbiomes had lower diversities. Specific bacterial genera like Clostridium, Streptococcus, Romboutsia, Paeniclostridium, Lactobacillus, Enterococcus, and Lactococcus were associated with the ferrets. The significant differences in the microbiomes between ferrets and cats suggest unique gastrointestinal care requirements for ferrets, particularly if they have digestive issues. Future studies should explore how the gut microbiomes of sick ferrets differ from healthy ones and how they respond to diet and medical treatments. The domestic ferret (Mustela putorius furo) is a popular companion pet in the United States, with an estimated population of 500,000. Despite being obligate carnivores with a fast digestive system, little is known about their gut microbiomes. This study aims to compare the fecal microbiomes of healthy domestic ferrets and cats, which are both obligate carnivores. We collected and analyzed stool samples from 36 healthy ferrets and 36 healthy cats, sequencing the V4 region of the 16S rRNA gene. Using QIIME 2, we assessed the alpha and beta diversities and identified the taxa differences. Compared to cats, ferrets exhibited a higher representation of Firmicutes and Proteobacteria, while Bacteroidota and Actinomycetota were more prevalent in cats. The ferrets' microbiomes displayed lower alpha diversities. The highly present bacterial genera in the gut microbiomes of ferrets included Clostridium sensu stricto, Streptococcus, Romboutsia, Paeniclostridium, Lactobacillus, Enterococcus, and Lactococcus. Notably, the ferrets' microbiomes significantly differed from those of cats. This research highlights the potential differences in gastrointestinal care for ferrets, emphasizing the need for tailored approaches. Future studies should explore microbiome variations in ferrets with gastrointestinal issues and their responses to dietary and medical interventions. [ABSTRACT FROM AUTHOR]

Simple Summary: Burgeoning interest in the emotional experiences and cognitive abilities of dogs has led to novel methods to measure and improve canine welfare. Dog toys, in particular, are commonly thought to benefit dogs' mental and physical health. In this study, we examined the effect of introducing new toys to companion dogs. Our results showed a slight improvement in some positive welfare measures in dogs who received more complex toys when compared to dogs who received less complex toys and those who received no toys. However, this difference was not statistically significant and we found no differences in subjects' eating rate or activity levels. While research has found that toys may improve the welfare of kenneled dog populations (shelter- and laboratory-housed dogs), our findings did not find the same to hold with pet dog populations. We discuss the relevance of the study population and the welfare measures used in attempts to study "enrichment" in animals. Retail dog toys are often provided to companion animals to provide cognitive and physical stimu- lation and improve the animals' quality of life. These toys, sometimes known as "enrichment toys", have been shown to play a role in increasing appetite and activity levels and decreasing undesirable behaviors (e.g., barking, self-isolating behaviors) in some domestic dog (Canis familiaris) populations. In this study, we evaluate the effect of toys on appetite, activity levels, and positive affective states as measures of well- being in companion dogs. Behaviors were compared before and after regular interactions with different types of toys over twelve days. We found that provisioning companion dogs with toys did not significantly alter their activity level, rate of food consumption, or cognitive bias. While dogs who received more complex toys showed a slightly improved cognitive bias, there were no significant differences in behaviors be- tween the subjects who received "less complex" toys (e.g., a bone, ball) and "more complex" toys (e.g., puzzle toys). We conclude with reflections on the relevance of our subject population to the result seen, and on the different forms of the cognitive bias test. [ABSTRACT FROM AUTHOR]

Simple Summary: Senior pets can suffer from a wide range of age-related diseases that cause distress to the pet and their owner. Diet is one of the easiest ways for improving pet health that can be accessed by pet owners. Fibre is one of the most important ingredients for maintaining gut health. This study aimed to understand whether a novel blend of prebiotic fibres added to a nutritionally complete commercial diet could improve the health of senior dogs. Results show that the prebiotic-blend could improve the gut health of senior dogs as measured by improved faecal quality and beneficial changes to the microbiome. The developed prebiotic fibre blend could have a range of future dietary applications. Senior pets can suffer from a wide range of age-related diseases that can impact the quality of life for the pet and the relationship between a pet and their owner. Dietary fibre plays a key role in shaping the gastrointestinal health in mammalian species. The aim of this study was to investigate the impact of a novel prebiotic fibre blend containing sugar beet pulp, galacto-oligosaccharides, and cellulose on the health of senior dogs when fed on top of a background commercial dry diet. Thirty-two dogs aged >8 years received the prebiotic fibre blend as a dietary topper for 21 days on top of a nutritionally complete diet using a cross-over study design. The prebiotic fibre blend improved the gastrointestinal health of senior dogs as measured through improved faecal quality scores, a reduction in faecal pH, changes to the taxonomic composition of the gut, and a reduction in faecal branched-chain fatty acids, which are markers for proteolytic degradation. Broader systemic measures, such as changes to serum cytokines, were not impacted by the prebiotic fibre blend. In conclusion, a novel prebiotic fibre blend containing sugar beet pulp, galacto-oligosaccharides, and cellulose improved the gastrointestinal health of senior dogs and could have a range of potential future dietary applications.

Simple Summary: Pandemics are predicted to increase in frequency, so it is important that lessons are learned from COVID-19. As half of the world's population has a companion animal in the home, it is also important to understand the pandemic experiences of both animal caregivers and their animals. Since 2020, a vast amount of literature has been published on the psychological well-being of people with companion animals during the COVID-19 pandemic. This review examined the effect of caring for companion animals on humans' psychological well-being during this global crisis, as well as the benefits and challenges of having a companion animal during the pandemic and perceived effects on animals' well-being. We reviewed one hundred and twenty-two studies and found positive, negative, and neutral psychological effects of having a companion animal during the pandemic. Animals were described as providing routine, a sense of purpose, distraction from COVID-19 worries, companionship, and emotional support. However, caregivers also reported worries about access to animal food and veterinary services, fears about COVID-19 transmission, concerns about being unable to financially support their animals, and worries about what would happen to their animals if their caregivers were hospitalized. Animals themselves experienced both positive and negative effects of being in lockdown. It is important to understand the effects of the COVID-19 pandemic on animal caregivers and their companion animals in order to inform responses to future crises. Prior research is inconsistent, with the benefits of animal companionship believed to be overstated. In this scoping review, we searched four electronic databases and hand-searched reference lists of included studies. Over 4000 citations were found, and 122 were included in the review. Reflecting on the pre-COVID literature, quantitative evidence of the association between psychological well-being and animal companionship during the pandemic was mixed, with numerous positive, negative, and null findings reported. Studies highlighted the benefits of animal companionship during the pandemic, with animals reported to provide their caregivers with a routine, a sense of greater purpose, a positive distraction from COVID-19, companionship, and emotional support. However, participants also reported concerns about meeting animals' needs, fears of animals catching or spreading the virus, and financial worries. Concerns about what would happen to animals if caregivers were hospitalized led some to delay COVID-19 testing or treatment. Animals also experienced benefits (such as increased companionship and calmer mood) and negative impacts (such as increased clinginess and separation anxiety). Companion animals should be a key consideration in emergency preparedness plans. [ABSTRACT FROM AUTHOR]

Simple Summary: We introduce the term and evaluate the phenomenon of pseudoresistance to antiseizure-medication in canine epilepsy cases initially diagnosed with medication-resistant epilepsy. Our study shows that around one third of the patients initially diagnosed with medication-resistant epilepsy had in fact other underlying reasons for their drug resistance (they were in fact pseudoresistant) and all but one of these cases responded to modification of the initial therapy protocol. Epilepsy is a common neurological disorder in veterinary practice, complicated by frequent occurrence of medication-resistant epilepsy. In human medicine, it has been noted that some patients with medication-resistant epilepsy have in fact other reasons for their apparent medication-resistance. The aim of this retrospective study was to describe the issue of pseudoresistance using as an example a population of dogs presented with presumed medication-resistant epilepsy and provide an in-depth review of what is known in human medicine about pseudoresistant epilepsy. One-hundred fifty-two cases were identified with medication-resistant epilepsy, of which 73% had true medication-resistant epilepsy and 27% patients had pseudoresistance. Low serum anti-seizure medication levels were the most common cause of pseudoresistance, present in almost half of the cases (42%), followed by inadequate choice of drugs or dosages (22%), misclassification (22%) or misdiagnosis (9%) of epilepsy and poor compliance (9%). All cases of pseudoresistance, except for one, responded to a modification of the initial therapy protocol. Pseudoresistance can bias clinical trials, misinform the clinical decision-making process, delay diagnosis and treatment, and misinform owners about their pets' prognosis. A substantial proportion of these cases can have improvement of their seizure frequency or achieve seizure freedom upon modification of their therapeutic protocol. [ABSTRACT FROM AUTHOR]

Simple Summary: Pet air travel has increased in the last decade, and 6% of pets in the US board a plane every year. Dogs have been reported to make up 58% of pets travelling worldwide. Despite this, there is little data available about air travel in dogs. A total of 635 questionnaires were collected from dog owners whose dogs had travelled by air in the last 12 months to obtain initial data on international dog air travel and how well dogs cope with air travel physically, mentally, and emotionally. Data on how dogs were being prepared for air travel, specifically regarding stress management, were also collected. Results showed that most dogs cope with and recover well from air travel but that there is a group of individuals who suffer physical, mental, and emotional ill health consequences during or after air travel, including death. Most dog owners planned air travel themselves, and over half did not seek professional advice. Stress management products such as anxiolytic medication and supplements or pheromones were only used in one-quarter of canine travellers. This study presents opportunities for all stakeholders of pet air travel, including owners, veterinarians, airlines, airports, and pet shippers, to improve pet welfare during air travel. It is estimated that 2 million domestic animals travel on commercial flights every year in the US alone and that dogs make up 58% of pets travelling worldwide. There has been little research on the welfare effects of air travel on dogs. The purpose of this owner-reported study was to understand how well dogs cope with and recover from air travel from a physical, mental, and emotional health perspective. An online survey questionnaire was distributed globally to pet owners whose dogs had travelled by air in the last 12 months, and the results were collected and analysed. Information was received about dog and owner demographics, logistics, and preparation for travel, as well as the dog's experience of air travel. Results showed that most dogs cope with and recover well from air travel but that there is a group of individuals who suffer physical, mental, and emotional ill health consequences during or after air travel, including death. Stress management products such as anxiolytic medication, supplements, and pheromones were underutilised and, in some instances, actively discouraged. More education of all stakeholders of pet air travel is needed to improve the physical, mental, and emotional health and welfare of canine air travellers. [ABSTRACT FROM AUTHOR]

Simple Summary: Companion animals are increasingly being recognised as important contributors to the spread of antimicrobial-resistant bacteria. The present work aimed to measure the antimicrobial drug prescribing in dogs and cats in the Campania Region, Italy by analysing the Veterinary Electronic Prescriptions (VEPs) between 2019 and 2020. The overall percentage of antibiotics prescribed in dogs was 65% and in cats 31.4%. In dogs, 90.5% of VEPs prescribed for systemic treatment included an antimicrobial Critically Important or Highly Important or Important for human medicine. The antimicrobials prescribed were mainly metronidazole–spiramycin (29.7%), amoxicillin–clavulanic (19.6%), enrofloxacin and cephalexin in dogs (16.5%) and enrofloxacin (22.6%) and amoxicillin–clavulanic acid (21.4%) in cats. Based on the results, the widespread use of broad-spectrum antimicrobials and the use of molecules for which limitations should be observed according to the EMA guidelines has emerged. Companion animals are increasingly being recognised as important contributors to the spread of antimicrobial-resistant bacteria. The present work aimed to measure the antimicrobial drug prescribing in dogs and cats in the Campania Region, Italy by analysing the Veterinary Electronic Prescriptions (VEPs) between 2019 and 2020. The medical records associated with antimicrobial drug prescriptions were collected according to the drug administration (systemic or topical) and the rationale for the treatment chosen. In the period under investigation, 166,879 drugs were prescribed of which 129,116 (73.4%) were antimicrobial. A total of 83,965 (65%) antibiotics were prescribed to dogs, 40,477 (31.4%) to cats, and 4674 (3.6%) to other companion animals. In dogs, 90.5% of VEPs prescribed for systemic treatment included an antimicrobial Critically Important or Highly Important or Important for human medicine (WHO, 2018). The most widely prescribed class was fluoroquinolones. The antimicrobials prescribed were mainly metronidazole–spiramycin (29.7%), amoxicillin–clavulanic (19.6%), enrofloxacin and cephalexin in dogs (16.5%) and enrofloxacin (22.6%) and amoxicillin–clavulanic acid (21.4%) in cats. Based on the results, the widespread use of broad-spectrum antimicrobials and the use of molecules for which limitations should be observed according to the EMA guidelines has emerged.

Simple Summary: The high radiant heat load of tropical regions imposes challenges on the welfare of imported temperate dog breeds, especially when owners' awareness does not result in willingness to change their attitudes towards the care of their dogs, e.g., by choosing more thermally comfortable times to walk with them. Based on an online questionnaire answered by Siberian Husky dogs' owners, we found that respondents mentioned several heat defense behaviors expressed by their dogs, perceived them as low-heat-tolerant animals and were more likely to walk with dogs during times of less solar input. However, the availability of time was reported by owners as the main reason for taking their dogs for a walk during times of high solar input. In conclusion, the owners' perception that Siberian Huskies living in Brazil are heat-sensitive dogs was likely to reflect positive attitudes via avoidance of exposing them to extreme hot conditions during daily walks. The management of the thermal environment to which dogs are exposed should be included in strategies to improve their welfare. An online questionnaire was administered to 624 owners of Siberian Husky dogs residing in Brazil, with the objective of assessing their perceptions regarding their dogs' capacity to adapt to heat, and its association with the owners' routine care. Owners who believed that dogs are low-heat-tolerant animals were more likely to report heat response behaviors from their dogs. Overall, owners reported walk with their dogs during early morning, late afternoon and nighttime. They also reported solar radiation as the primary criteria for determining the time to walk with their dogs. However, owners who reported walking with their dogs at noon mentioned time availability as their primary criteria. In conclusion, owners perceive Siberian Husky dogs living in Brazil as being poorly adapted to heat, and this perception appeared to influence their positive attitudes towards protecting their dogs from heat stress by choosing to walk them during times with less solar exposure. However, the lack of time for owners to walk with their dogs during cooler periods can still be a risk factor in exposing the animals to extreme hot conditions. [ABSTRACT FROM AUTHOR]

Simple Summary: Wittgensteinian ethicists argue that we should not rely on a set of principles if we want to know how to treat non-human animals. Instead, we should look at how we witness and encounter animals in our lives. We admire wild animals, we feed our pets, and we cure them as patients. For Wittgensteinian animal ethicists, moral reflection should start from these ways of thinking about animals. However, our understanding of animals can change depending on context and circumstance. Not everyone thinks about animals in the same way. It is, therefore, important that Wittgensteinian animal ethicists are informed about the ways that people think about animals. We argue that this information should come from data gathered by social sciences such as sociology, psychology or anthropology. Wittgensteinian approaches to animal ethics highlight the significance of practical concepts like 'pet', 'patient', or 'companion' in shaping our understanding of how we should treat non-human animals. For Wittgensteinian animal ethicists, moral principles alone cannot ground moral judgments about our treatment of animals. Instead, moral reflection must begin with acknowledging the practical relations that tie us to animals. Morality emerges within practical contexts. Context-dependent conceptualisations form our moral outlook. In this paper, we argue that Wittgensteinians should, for methodological reasons, pay more attention to empirical data from the social sciences such as sociology, psychology or anthropology. Such data can ground Wittgensteinians' moral inquiry and thereby render their topical views more dialectically robust. [ABSTRACT FROM AUTHOR]

Simple Summary: A major factor in dog welfare is a good relationship with their humans. In turn, living with a dog supports the wellbeing and even the mental and physical health of their human masters. In fact, the Palaeolithic partnership between humans and wolves was social and cooperative from its beginning; living with humans selected for tame wolves and thereby turned them into dogs, fine-tuning the initial social match even more. Why humans can be social with other animals at all may be explained via a common "social toolbox"—a social brain and physiology—shared between humans and other animals because of both a common phylogeny and parallel evolution. Such "social kinship" between humans and other animals makes it possible to conclude that satisfying the social needs of dogs by providing cooperative and empathic human leadership is crucial for their welfare, and that anthropomorphising dogs on the basis of informed human empathy is not as negative as it may sound; it seems rather that it is an adequate basis for a good partnership for mutual wellbeing. Wolves, dogs and humans share extremely social and cooperative minds. These similarities are rooted in phylogenetic homology and in the convergence of neuronal and physiological mechanisms, particularly the brain, in the functioning and communication of basic affects and in the mechanisms of stress and calming. The domesticated wolves called dogs are particularly close companion animals. Both Palaeolithic humans and wolves were hypercursorial hunters, cooperating in complex and prosocial ways within their clans with respect to hunting, raising offspring, and defending against conspecific and heterospecific competitors and predators. These eco-social parallels have shaped the development of similar social mindsets in wolves and humans. Over the millennia of domestication, this social match was fine-tuned, resulting in the socio-cognitive specialists humans and dogs, possessing amazingly similar social brains and minds. Therefore, it can be concluded that the quality of their relationships with their human masters is a major factor in the wellbeing, welfare and even health of dogs, as well as in the wellbeing of their human partners. Based on their strikingly similar social brains and physiologies, it can be further concluded that anthropomorphically applying human empathy to dogs in an educated manner may not be as inappropriate as previously thought.

Simple Summary: SARS-CoV-2, the virus lead to global COVID-19 pandemic, is thought to have an animal origin. From humans, SARS-CoV-2 then transmitted to multiple animal species. Infection transmission between species can lead to reservoir species that harbor the virus and promote its reemergence. Between-species viral transmission can also promote viral mutations that make it more harmful to humans or animals or more transmissible to critical populations (e.g., endangered species, agricultural animals). Characterizing SARS-CoV-2 infections across species became a priority early in the pandemic to help understand transmission and susceptibility. In this study, we tested 792 domestic and wild animals around Ohio between May 2020 and August 2021. We focused on high risk animals including sick animals, animals highly susceptible to SARS-CoV-2 (e.g., cats, primates), and highly congregated animals or those with frequent human contact (e.g., shelters, barns, pets). Of the 34 species we tested, SARS-CoV-2 virus was not detected in any sample. Our sampling was largely conducted prior to the peak of human SARS-CoV-2 in Ohio, and this lack-of-detection does not imply lack of susceptibility or transmission between species. Importantly ongoing surveillance is still critical to predicting and preventing future SARS-CoV-2 infections in humans and animals. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in humans in late 2019 and spread rapidly, becoming a global pandemic. A zoonotic spillover event from animal to human was identified as the presumed origin. Subsequently, reports began emerging regarding spillback events resulting in SARS-CoV-2 infections in multiple animal species. These events highlighted critical links between animal and human health while also raising concerns about the development of new reservoir hosts and potential viral mutations that could alter the virulence and transmission or evade immune responses. Characterizing susceptibility, prevalence, and transmission between animal species became a priority to help protect animal and human health. In this study, we coalesced a large team of investigators and community partners to surveil for SARS-CoV-2 in domestic and free-ranging animals around Ohio between May 2020 and August 2021. We focused on species with known or predicted susceptibility to SARS-CoV-2 infection, highly congregated or medically compromised animals (e.g., shelters, barns, veterinary hospitals), and animals that had frequent contact with humans (e.g., pets, agricultural animals, zoo animals, or animals in wildlife hospitals). This included free-ranging deer (n = 76 individuals), free-ranging mink (n = 57), multiple species of bats (n = 59), and other wildlife in addition to domestic cats (n = 275) and pigs (n = 184). In total, we tested 792 individual animals (34 species) via rRT-PCR for SARS-CoV-2 RNA. SARS-CoV-2 viral RNA was not detected in any of the tested animals despite a major peak in human SARS-CoV-2 cases that occurred in Ohio subsequent to the peak of animal samplings. Importantly, we did not test for SARS-CoV-2 antibodies in this study, which limited our ability to assess exposure. While the results of this study were negative, the surveillance effort was critical and remains key to understanding, predicting, and preventing the re-emergence of SARS-CoV-2 in humans or animals.
