Simple Summary: Although agonistic interactions between cats are often regarded clinically as a source of stress, there is currently limited research evidence regarding the welfare impact of keeping multiple cats as pets. The aim of this study was to compare welfare indicators between cats living in single and multi-cat households, as well as between cats living in multi-cat households where agonistic behaviour was/was not reported by owners. Indicators included a spatial judgment bias task (JBT) and the cat stress score (CSS). CSSs were higher in cats from single compared with multi-cat households. CSSs were lower for cats that showed a more 'pessimistic' response in the JBT, suggesting these cats appeared to be less stressed. JBT results did not vary depending on the presence of, or reports of agonistic behaviours between, cohabiting cats. These data suggest that mood states (as measured by the JBT) were not impacted by the social groupings investigated, and that cats from single-cat households showed more signs of stress (as measured by CSS) than those in multi-cat households. Alternative explanations cannot be discounted, particularly due to the narrow sample population and broad scope of husbandry conditions that were unaccounted for. Further research is warranted to explore the extent to which variables that could not be controlled may have confounded findings. Although agonistic interactions between cats are often regarded clinically as a source of stress, there is currently limited research evidence regarding the welfare impact of keeping multiple cats as pets. The aim of this study was to compare welfare indicators between cats living in domestic single and multi-cat households, as well as between multi-cat households where agonistic behaviour was/was not reported by owners. Indicators included a spatial judgment bias task (JBT), where longer latencies to ambiguous probes are interpreted as being related to a more 'pessimistic' mood state, and the cat stress score (CSS), where high scores are indicative of high stress levels. Of 128 focal cats between the ages of 9–22 months, 94 were from multi-cat households, 126 had useable CSS data and 42 had JBT results suitable for analysis. CSSs were significantly lower for cats showing a more 'pessimistic' response in the JBT. It is possible that the cats that appeared to be the most relaxed may have been showing inactivity relating to negative affective states and/or were the least active/food motivated, and therefore slower in the JBT. CSSs were significantly higher in cats from single compared with multi-cat households, and did not vary with reports of agonistic interactions in multi-cat households. JBT results did not vary depending on the presence of, or reports of agonistic behaviours between, cohabiting cats. These data suggest that cats from single-cat households may be more likely to show signs of acute stress than those in multi-cat households. Alternative explanations are possible. For example, lower CSSs in the multi-cat group may reflect 'relief' effects resulting from separating cats for the test period, or inactivity relating to negative affective states. Due to the narrow sample population and broad scope of husbandry conditions, the potential for confounding variables limits the degree by which results can be used to inform causation of the relationships identified. Further research is warranted to replicate this work and explore potential confounders. [ABSTRACT FROM AUTHOR]

Simple Summary: Initial COVID-19 lockdown restrictions in the United Kingdom (23 March–12 May 2020) prompted many people to change their lifestyle. We explored the impact of this lockdown phase on pet dog welfare using an online survey of 6004 dog owners, who provided information including dog management data for the 7 days prior to survey completion (4–12 May 2020), and for February 2020 (pre-lockdown). Most owners believed that their dog's routine had changed due to lockdown restrictions. Many dogs were left alone less frequently and for less time during lockdown and were spending more time with household adults and children. During lockdown, dogs were typically walked less often and for less time daily, with factors related to the dog, owner, household, and location of the home associated with the extent to which dog walking had been reduced. Dogs were more likely to be walked on a lead and had fewer opportunities to interact with other dogs during lockdown. However, many dogs had more play/training sessions with their owners and were given toys more frequently during lockdown. These changes to dog management have the potential for longer-term welfare problems such as increased likelihood of dogs displaying separation-related behaviour as lockdown measures relax. Initial COVID-19 lockdown restrictions in the United Kingdom (23 March–12 May 2020) prompted lifestyle changes for many people. We explored the impact of this lockdown phase on pet dogs using an online survey completed by 6004 dog owners, who provided information including dog management data for the 7 days prior to survey completion (4–12 May 2020), and for February 2020 (pre-lockdown). We explored associations between potential predictors and four outcomes relating to changes pre-/during lockdown (reduction in number and duration of walks; increased frequency of play/training, and provision of toys). Most owners (79.5%) reported their dog's routine had changed compared to pre-lockdown. There was a four-fold increase in the proportion not left alone for >5 min on any day during a weekly period (14.6% pre-lockdown, 58.0% during lockdown), with the proportion being left for ≥3 h at a time decreasing from 48.5% to 5.4%. Dogs were walked less often and for less time daily during lockdown, with factors related to the dog, owner, household, and home location associated with changes to walking practices. Many dogs had more play/training sessions and were given toys more frequently during lockdown. Decreased walk duration was associated with increased odds of play/training opportunities and toy provision. These changes to dog management have the potential for immediate and longer-term welfare problems. [ABSTRACT FROM AUTHOR]

Simple Summary: For dogs and their owners to live in harmony, owner expectations and the behaviour of their dogs need to be aligned. Limited socialisation can contribute to the development of undesirable behaviours, so the reduced socialisation opportunities for many puppies during the COVID-19 lockdown is a concern. This United Kingdom/Republic of Ireland study used data collected between May 2016 and November 2022 to examine the impact of age and lockdown phase (pre-, during, and post-) on the types of socialisation experiences of 8-to-19-week-old puppies and the recency of socialisation experiences of 6-month-old puppies. The findings showed that puppies under 19-weeks had more types of experiences as they aged, and during pre-lockdown compared to post-lockdown, but not between other lockdown phases. Most 6-month-old puppies had met new adults or dogs, familiar dogs, or children within the last 1–7 days, regardless of lockdown phase. However, during lockdown, 6-month-old puppies experienced longer periods between meeting new adults in their homes. Overall, lockdown had a smaller impact on socialisation experiences than expected, but the quantity and quality of these experiences may have been affected. Future research will explore whether these early-life experiences relate to adult behaviour as the dogs in the study grow older. Limited socialisation can contribute to the development of undesirable dog behaviours. The COVID-19 lockdown potentially limited socialisation opportunities, which may negatively impact the future behaviour of puppies raised during lockdown. Data were gathered from longitudinal study participants in the United Kingdom/Republic of Ireland via multiple questionnaires between May 2016 and November 2022. The impact of age and lockdown phase (pre-, during, and post-) on the types of socialisation experiences of 8-to-19-week-old puppies and the recency of socialisation experiences of approximately 6-month-old puppies were examined. Puppies under 19-weeks had significantly more types of socialisation experiences (from a predefined list) as they aged, and pre-lockdown compared to post-lockdown, but not between other lockdown phases. Most 6-month-old puppies had met a new adult or dog outside the household, a familiar dog, and/or a child within the last 1–7 days, and this was similar between lockdown phases. During lockdown, 6-month-old puppies experienced longer periods between meeting a new adult in their home. Puppies were hypothesised to have had fewer experiences during lockdown, but this was not found. However, the quantity and quality of these experiences may have been affected. Future research within this longitudinal study will explore relationships between the timing and type of experiences had by puppies and their subsequent behaviour. [ABSTRACT FROM AUTHOR]

Objective: To use a previously validated veterinary clinical examination sheet, Liverpool Osteoarthritis in Dogs (LOAD) questionnaire, combined with kinetic and kinematic gait analysis in dogs with/without mobility problems to demonstrate the capacity of a novel clinical metrology instrument ("GenPup-M") to detect canine mobility impairments. Design: Quantitative study. Animals: 62 dogs (31 with mobility impairments and 31 without mobility impairments). Procedure: The dogs' clinical history was obtained from owners and all dogs underwent a validated orthopaedic clinical examination. Mobility impairments were diagnosed in the mobility impaired group based on clinical history and orthopaedic examination. Owners were asked to complete GenPup-M along with a previously validated mobility questionnaire (Liverpool Osteoarthritis in Dogs (LOAD)) to identify construct validity. As a test of criterion validity, the correlation between instrument scores and the overall clinical examination scores, along with force-platform obtained peak vertical forces (PVF) were calculated. GenPup-M underwent internal consistency and factor analysis. Spatiotemporal parameters were calculated for dogs with/without mobility impairments to define the gait differences between these two groups. Results: Principal Component Analysis identified GenPup-M had two components with Eigenvalues >1 ("stiffness/ease of movement" and "willingness to be active/exercise"). Cronbach's α was used to test internal consistency of GenPup-M and was found to be "good" (0.87). There was a strong, positive correlation between GenPup-M and LOAD responses (r2 = 0.69, p<0.001) highlighting construct validity. Criterion validity was also shown when comparing GenPup-M to clinical examination scores (r2 = 0.74, p<0.001) and PVF (r2 = 0.43, p<0.001). Quantitative canine gait analysis showed that there were statistically significant differences between peak vertical forces (PVF) of mobility impaired and non-mobility impaired dogs (p<0.05). Analyses of PVF showed that non-mobility impaired dogs more evenly distributed their weight across all thoracic and pelvic limbs when compared to mobility impaired dogs. There were also consistent findings that mobility impaired dogs moved slower than non-mobility impaired dogs. Conclusion and clinical relevance: GenPup-M is a clinical metrology instrument (CMI) that can be completed by dog owners to detect all mobility impairments, including those that are early in onset, indicating the versatility of GenPup-M to assess dogs with and without mobility impairments. Results of the study found that GenPup-M positively correlated with all three objective measures of canine mobility and consequently showed criterion and construct validity. Owner-reported CMIs such as GenPup-M allow non-invasive scoring systems which veterinary surgeons and owners can use to allow communication and longitudinal assessment of a dog's mobility. It is anticipated that GenPup-M will be used by owners at yearly vaccinations/health checks, allowing identification of any subtle mobility changes, and enabling early intervention.

Simple Summary: Owners' understanding of dog behaviour influences dog welfare. This study explored owners' experiences and perceptions of dog behaviour. Data came from an ongoing UK/ROI study of dogs. Survey questions when dogs were 12/16 weeks (data combined), 6, 12, 18 and 24 months were analysed. Data were explored with two approaches: (1) qualitative thematic analysis and (2) quantitative text analysis. Responses to 'other information' questions and those regarding owner-reported problem behaviours were explored to understand owners' experiences/understanding of dog behaviour (1). Responses to the 'other information' questions were evaluated to understand how sentiment in the text and in word use changes over time (2). The proportion of positive: negative sentiments increased with the dog's age. At the first time point, 'bite' was the most common word, later replaced by words related to 'love'. Owners referred to the 'dog's biology', 'personality/deliberate action' and 'external influences' when explaining dogs' behaviour. Problematic behaviours of young dogs were seen as 'mischievous', unintentional and context-specific. Similar behaviours shown by older dogs were described as 'deliberate'. Both positive and negative experiences of dog ownership were identified. Free-text survey responses are a useful resource for exploring data but should be interpreted cautiously, as not all respondents answer these questions. Owners' understanding of dog behaviour influences dog welfare. This study aimed to investigate owners' experiences of living with dogs and perceptions of dog behaviour/behaviour change. Data from an ongoing UK/ROI longitudinal study of dogs were used. Open-ended survey data (n = 3577 comments, n = 1808 dogs) when dogs were 12/16 weeks (data combined), 6, 12, 18 and 24 months were analysed to cover the dog's puppyhood/adolescence. To evaluate the usefulness of open-ended survey questions, both quantitative textual and qualitative thematic analyses were employed. Textual analysis identified an overall positive sentiment at all timepoints; the proportion of positive: negative sentiments increased with the dog's age. Words related to 'love' were the most frequent descriptors at all but the first timepoint, when 'bite' was the most frequent descriptor. Qualitative analysis helped to identify that owners attribute dog behaviour to 'Dog's biology', 'Personality/deliberate action' and 'External influences'. Analysis of open-ended survey responses helped to identify changes in perception over time. When dogs were young, owners described problematic behaviours as 'mischievous', unintentional and context-specific. Similar behaviours shown by older dogs were seen as 'deliberate'. Both positive and negative experiences of dog ownership were identified. However, as not all respondents answered open-ended questions, the generalisability of our findings is limited.

Simple Summary: Cats and dogs can form friendly relationships and conflict between them can harm their welfare. This study aimed to investigate factors related to 'only desirable' puppy behaviour (defined as being uninterested, ignored the cat or interacted in a calm way) towards existing household cats following introduction. Owners' perceptions of the emerging cat-dog relationships were also explored. Quantitative and qualitative analyses were used to examine survey data collected as part of an ongoing study of dog health and behaviour. Of 4678 puppies, 26.7% lived with at least one cat. At the time of survey completion, 1211 puppies had been introduced to the household cat. The most common behaviours shown towards cats by puppies were: playing (58.9%), being overexuberant or over-excited (56.6%) and chasing (48.6%). Just 7.3% of puppies showed 'only desirable' behaviours. Puppies were more likely to show 'only desirable' behaviours when introduced before 12 weeks of age, gradually, and when they lived in a household with other dogs(s). Two styles of introductions were identified—owner-led and pet-led. Owners' expectations of the cat-dog relationship differed depending on the style of introduction. Early, gradual, owner-led introductions of puppies to household cats can help them form a friendly relationship. Although cats and dogs can live amicably, inter-species conflict can result in poor welfare. Species introduction can impact the development of the cat-dog relationship. This study aimed to identify factors associated with owner reported 'only desirable' puppy behaviour (defined as the puppy being uninterested, ignored the cat and/or interacted in a calm way) following introduction to existing household cats, and to explore perceptions of the emerging cat-dog relationship. Owner-reported data collected as part of a longitudinal study of canine health and behaviour were used. Of 4678 puppies, 26.7% lived with at least one cat. Of the 1211 puppies who had been introduced to the household cat at the time of survey completion, playing (58.9%), being overexuberant or over-excited (56.6%), and chasing (48.6%) were the most common behaviours displayed towards cats. 'Only desirable' behaviours were shown by 7.3% of puppies. Multivariable logistic regression showed early (puppies aged <12 weeks), gradual introductions and living in a multi-dog household increased the odds of 'only desirable' behaviours. Qualitative analysis revealed two styles of introductions—owner-led and pet-led. Owners who led introductions anticipated amicable relationships between pets, whilst owners who let pets introduce themselves did not. Early, gradual, owner-led introductions of puppies to household cats should be encouraged. [ABSTRACT FROM AUTHOR]

Simple Summary: Dogs can develop separation-related behaviours (SRBs), such as barking/howling, pacing, toileting or destroying household items when they are left without human company. These behaviours can be problematic for owners but are also welfare concerns for the dogs because they mean the dog is in a negative emotional state. Many dog owners have been able to spend more time at home with their pets during the COVID-19 pandemic, and there have been concerns this will increase risks of SRB when dogs are left alone for longer again. Here, we surveyed a group of dog owners in the United Kingdom (UK) twice during 2020. In the first survey, we asked owners about their dogs' behaviour before the pandemic, in February 2020, and at the time of the first lockdown; we then surveyed them again in October 2020 when restrictions had eased. Whether dogs showed SRBs or not changed considerably over the months of the study, and whilst one in two dogs with pre-existing SRBs were no longer showing them in October 2020, one in ten dogs who had previously not shown SRBs before the pandemic were found to have developed SRBs in October. Risk of developing SRBs was found to be linked to the change in time left alone during the lockdown, with dogs whose time alone reduced the most being most at risk of developing new SRBs in October. Separation-related behaviours (SRBs), including but not limited to vocalisation, pacing, destruction and toileting, occur in the absence of human company. As well as being problematic for the dogs' owners, such behaviours indicate that the dogs' emotional state is compromised. As part of the COVID-19 pandemic, time spent alone decreased considerably for many pet dogs, leading to concerns about the development of SRBs when dogs are left alone more again. The main aim of this study was to test the hypothesis that dogs whose time left alone decreased most (compared to a February 2020 pre-COVID baseline) would be at greatest risk of developing new signs of SRB when time left alone increased again. To achieve this aim, we utilised survey data gathered from dog owners between 4th May and 3rd July 2020, during the first COVID-19 'lockdown' period in the United Kingdom (UK), and a follow-up survey of the same dog-owner cohort, completed when restrictions had eased between 10th October and 2nd November 2020. Individual dogs fluctuated considerably in whether they showed signs of SRB or not across the study period (n = 1807). Overall, the prevalence of SRB in the population decreased from 22.1% to 17.2%, as did the time dogs were left alone for between February and October 2020. However, 9.9% of dogs had developed new signs of SRB by the follow-up survey in October 2020, with dogs whose leaving hours decreased most during lockdown restrictions being at increased risk of developing SRBs. These findings have implications for our understanding of the etiology of SRB, by showing a link between changes in owner routine and SRB risk. [ABSTRACT FROM AUTHOR]

Simple Summary: On 23 March 2020, the UK Government introduced a nationwide lockdown as part of efforts to reduce the impact of COVID-19. Lockdown control measures led many dog owners to make changes to their daily routines. This study aimed to explore how the experience of dog ownership in the United Kingdom (UK) was impacted during this lockdown. Data for this research came from open-ended survey questions on the impact of COVID-19 on dog ownership, and electronic diary entries. Three key themes emerged from the data: spending time at home with dog(s), walking practices, and behaviour and training. Owners enjoyed spending more time than usual with their dog(s) but understood that spending increased time with them may lead to the dog(s) struggling in the future when left alone. However, very few owners gave their dog(s) "alone time" during the lockdown. Owners valued the opportunity to walk their dog(s) as part of their permitted daily exercise, but some felt that lockdown restrictions on exercise did not allow them to provide their dog(s) with sufficient exercise. They also worried that lockdown guidelines restricted opportunities for dogs to interact with other dogs. Additionally, some owners noticed new problematic behaviours in their dog(s). Using these findings, we make suggestions on how dog welfare organisations might help to best support dog welfare. These include supporting dog owners in teaching their dogs to cope with being alone, even if owners do not need to leave their dogs alone. On 23 March 2020, the UK Government imposed a nationwide lockdown as part of efforts to mitigate the impact of COVID-19. This study aimed to explore how the experience of dog ownership in the UK was impacted during this lockdown. Data for this research came from open-ended survey questions and an electronic diary completed by members of the general public and participants involved in "Generation Pup", an ongoing longitudinal cohort study of dogs. A total of 10,510 free-text entries were analysed. Three major themes emerged: spending time at home with dog(s), walking practices, and behaviour and training. Owners valued having more time than usual with their dog(s) but also recognised that spending extra time with their dog(s) may negatively impact on the dog's future ability to cope when left alone. However, very few owners provided alone time for their dog(s) during the lockdown. The opportunity to walk their dog(s) as part of their permitted daily exercise was regarded positively, but walks under the lockdown guidelines were not always felt to be adequate with respect to providing sufficient exercise and opportunities for interaction with other dogs. Owners reported observing new undesirable behaviours in their dog(s) during the lockdown, including barking and dogs being "clingy" or vocalising when briefly left alone. Based on these findings, we suggest intervention strategies to best support dog welfare that include helping dog owners to teach dogs to cope with being alone, even if owners do not need to leave their dogs alone.
