Chronic pain accompanying many diseases significantly impairs the quality of life and induces various changes in the behavior of animals. The present case report describes a dog with persistent chronic pain. The clinical signs demonstrated by the dog e.g. sneezing, rubbing the viscerocranium with thoracic legs, shaking the head, and avoidance of touch, clearly suggested discomfort localized in the muzzle. The final diagnosis of nasal adenocarcinoma was reached after over a year from the appearance of the first symptoms of discomfort. In retrospect, it is clear that the changes in the dog's behavior were caused by chronic pain. Presentation of new behaviors should be a signal to the owner indicating certain disturbances in the animal's well-being. There is a need for cooperation between the pet owner, veterinary doctor, and animal behaviorist in order to regard behavioral changes as a clue for the diagnosis of pain experienced by the animal and for treatment of its causes.

The aim of the study was to assess the salivary cortisol level in search and rescue dogs during rescue search examinations. The research was carried out during open-field and disaster examinations for search and rescue dogs in Poland. Forty-one dogs took part in the study. Saliva was collected just before the search test and immediately after the search examination. The salivary cortisol level in dogs was marked and analyzed in relation to the sex, breed, type of examination, dogs' experience, and detection time. Salivary cortisol level in search and rescue dogs increases during the examination in both male and female dogs. Examination type affects salivary cortisol levels in male and female dogs. The sex of a search and rescue dog can be an important factor when choosing the specialty in which to train.

The aim of the study was to assess the relationship between the motor lateralization in dogs and the concentration of cortisol and tyrosine in their plasma during a visit to a veterinary clinic. The research group consisted of 56 dogs. Motor lateralization was tested by of an adhesive tape test. The stress intensity was assessed basing on the levels of cortisol and ft4 in the serum blood. The statistical analysis revealed that in the group of 56 dogs there were 14 left-pawed dogs, 36 right-pawed dogs, and 6 dogs did not show particular paw preference. The average cortisol levels in particular groups were as follows: 7.94 ug/dl, 3.92 ug/dl and 3.7 ug/dl, whereas the level of tyrosine in the subjects that demonstrated left-sided lateralization (mean ± SE) (1.95 ± 0.46 ng/dl) for those with right-side lateralization (1.56 ± 0.23 ng/dl) and ambilateral dogs (1.01 ± 0.22 ng/dl).

The aim of this study was to assess salivary cortisol level in dogs during admission and a three-day stay in a pet hotel. The study involved 20 dogs admitted to a pet hotel for a stay lasting for at least three consecutive days. The study group consisted of 10 small dogs and 10 medium-sized dogs, eight females and 12 males. Saliva was collected each day to assess cortisol levels. A stay in a hotel is a stressful situation for dogs, as evidenced by the increase in the salivary cortisol level. The highest salivary cortisol level was observed on the day of admission to the hotel. The median salivary cortisol level in the dogs on the consecutive days was 2.7 ng/ml on admission, 2.1 ng/ml after 24 hours, and 1.9 ng/ml after 48 hours. Depending on the size of the dog, the median salivary cortisol level was 2.8 ng/ml, 2.9 ng/ml and 2.4 ng/ml in the small dogs and and 2.2 ng/ml, 1.7 ng/ml and 1.2 ng/ml in the medium sized dogs on the consecutive days.

Objectives The aim of the study was to analyse hair cortisol levels in cats whose owners had reported behavioural problems and undesirable behaviour. In addition, feline hair cortisol levels were compared between sexes, for indoor and outdoor cats and also for cats living in single or multi-cat households. Methods In total, 55 cats participated in the study, including 31 females and 24 males from various households. The cats belonged to 25 different owners who answered a questionnaire survey. The biological material used for the research were 2–3 cm fragments of hair removed at the level of the skin with scissors by the owners from the cats’ lumbosacral area. The cortisol concentration in the samples was determined with the DRG Salivary Cortisol HS ELISA. Statistical analysis of the results was performed with Statistica 13.3. Results A tendency toward lower cortisol levels was found in outdoor cats vs indoor cats (U = 251.5, P = 0.066). It was also found that the cats exhibiting behavioural problems (eg, house soiling [eliminating outside the litter box]) or aggressive behaviour towards household members had statistically significantly higher hair cortisol levels (U = 162.0 [ P = 0.027] and U = 9.0 [ P = 0.040], respectively). Conclusions and relevance High levels of stress in cats can affect their interactions with other cats and with humans. The incidence of undesirable behaviour was observed more frequently in indoor cats. Significantly higher cortisol levels were found in cats that eliminated outside the litter box or that showed aggression towards their owners.

The accumulation of cortisol in hair and claws, which grow slowly, makes it possible to retrospectively assess chronic stress levels. The study involved 47 cats from a shelter for homeless animals. Hair from the lumbosacral region and the dead part of claws from the front paw were collected. The average cortisol levels were 0.85 ng/ml in the cats’ hair and 4.56 ng/ml in the claws. There was no significant relationship between cortisol levels in hair and claws. To date, too little research has been done on the correlation between cortisol levels in the hair and claws of cats. It is insufficient to unequivocally prove the existence of such a relationship.

The aim of this study was to evaluate the temperament of dogs on the basis of behavioral observations, with emphasis on 24 selected traits and behaviors. From the observations, the temperament of the dogs was determined and the animals were assigned to one of two personality groups: introvert or extrovert. The study involved 46 dogs. The agglomeration method, Pearson’s 1-r distance, and Ward’s binding method were used. As shown by the statistical analysis, 18 dogs (39%) were assessed as introverts and 28 dogs (61%) exhibited extrovert traits. To construct a model for the assessment of canine temperament using the identified traits, logistic regression was performed with the independent variables, number of extrovert traits (ETs) and introvert traits (ITs), and a dichotomous dependent variable (1 = extrovert, 0 = introvert), reflecting the assessment of the temperament of the dog based on the observations and results of the original questionnaire.

Search and rescue dogs are an important link in the search for missing persons. The aim of the study was to assess exam stress in search and rescue dogs and their guides. The study included 41 rescue teams taking exams of field and rubble specialties. The level of cortisol, which is the main glucocorticosteroid modulating stress reactions in humans and dogs, was analyzed. The biological material used to assess the hormone concentration was saliva collected in a non-invasive way. In total, 164 test samples were collected: two from the dog and two from the guide before and immediately after the exam. Rescue exams were shown to significantly increase salivary cortisol in both dogs and their guides. Strong interactions between cortisol levels in human&ndash, dog teams were also found with a more pronounced effect in female dog&ndash, female handler dyads.

The aim of the study was to assess the relationship between humans and animals and to analyze the opinions expressed by pet owners about cremation and burial of their dead pets. The survey-based study was carried out among 876 respondents, and data on the number of cremations performed in 2016-2021 obtained from an animal crematorium were analyzed. The statistical analysis assessed the correlations between the responses and the sex, education, and place of residence of the respondents. The responses were analyzed using the Pearson Chi-square test. The percentage data collected from the crematorium included the number of collective and individual cremations with their mutual percentage ratio in a year and the number of purchased memorabilia of the deceased pet over the five subsequent years. The statistical analysis was performed in the Statistica 13.3 program. The research results allow for the formulation of a conclusion about the constantly growing empathy for the four-legged members of families.

Populations of game are not confined to single ecosystems but function within higher-order units, e.g. ecological landscape. The basis for the establishment of the hunting complexes was the assumption that the existing game hunting grounds, i.e. the basic units implementing game management, are too small and do not cover the natural areas inhabited by game populations. Roe deer are flexible species and easily adapt to various site conditions, so they inhabit many different habitats, from large forest complexes, through small in-field tree stands and shrubs, to treeless grounds and field monocultures. The aim of the study was to determine a possible impact of environmental conditions prevailing in the hunting complexes of the Regional Directorate of State Forests (RDLP in Lublin) on the ontogenetic quality of roe deer. The study was conducted on 518 European roe deer (Capreolus capreolus) aged from 4 to 7 years (379 bucks and 139 does) harvested within hunting seasons 2010/2011–2013/2014. The results have shown that animals originating from areas with greater forest cover and denser stands are characterised by lower values of the mean ontogenetic quality parameters (carcase weight, kidney fat index, chest girth, weight of antlers) in comparison with animals from typical agricultural areas with fragmented forest complexes. These results indicate that, even in the case of such a eurytopic species as the roe deer, the ontogenetic quality differs between individual hunting complexes. The study has proved that strategies for hunting management of the roe deer should take into account the impact of the landscape structure, which provides a rationale behind creation of hunting complexes.

The aim of the work was to present contemporary pet name trends, especially for cats and dogs. It also attempts to identify the origins of pet names. The research data consisted of the pet names of patients of a veterinary clinic in the years 2014-2018. The pet names of 36,487 dogs and 14,518 cats were analyzed statistically. The results obtained revealed relationships between the animal-human relationship, the species and sex of the animals. Among the most common dog names were diminutive male names (Max) and names borrowed from culture or mythology (Nero, Ares). The most universal name was Kuba, which occurred in both male and female dogs and cats. Among cats the most numerous were those called by diminutives of the word cat (Kicia) or by female names (Zuzia) and unnamed animals. Statistical analysis indicates a link between naming and the species: there were more nameless animals among cats than among dogs. A relationship between naming and the sex of dogs and cats was also noted: males were nameless more often than females.

Veterinary medicine is developing just as rapidly as human medicine. New technologies and workflows improving the process of treating humans are often applied in veterinary medicine. The procedure commonly used in emergency medicine is triage, that is, a system of patient segregation. In many countries, it has also proved extremely useful in the treatment of animals. Triage is a study and classification of patients according to the urgency of treatment. Its aim is mainly to recognize among many patients those that require immediate medical assistance. These are the so-called priority patients with life-threatening conditions. Animal clinics modify triage to suit the needs of veterinary patients. It improves greatly the work of clinics, especially in emergency waiting rooms. The aim of this study was to discuss the use of segregation in veterinary patients and to present our own proprietary triage protocol for the veterinary patient: Card of Veterinary Patient Pre-segregation (industrial design Rp.21948).
