In these locations, features such as confinement, forced intraspecific and interspecific contact, and lack of environmental stimulation can diminish the welfare of dogs. One way to avoid poor welfare is to implement an environmental enrichment program for dogs in shelters, however, environmental enrichment items should be tested to evaluate their effectiveness and their ease of implementation and safety. Therefore, this study aimed to evaluate the effectiveness of two environmental enrichment items designed to improve the welfare of dogs kept in a shelter. Fifteen dogs, housed in trios, were studied. Two environmental enrichment items were offered to the dogs: nutritional-related (perforated plastic bottles filled with canine treats) and sensory-related (lavender oil). Behavioral data were collected before, during, and after the items were offered, using focal sampling and instantaneous recording methods, with a sampling interval of 1 min. The effectiveness of the items was evaluated using Generalized Linear Mixed Models (GLMMs). Food enrichment increased foraging and activity behaviors in the dogs, but not positive social behaviors. On the other hand, olfactory enrichment decreased jumping and vocalizing and increased the display of climbing on the pen’s door. Both items proved to be safe for the dogs. It is of utmost importance for shelters to enhance animal welfare by constructing larger and more stimulating bays and implementing environmental enrichment programs for the animals. The results of this study show that an enrichment program can assist in improving the welfare of dogs kept in shelters.</div></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"80 ","pages":"Pages 28-38"},"PeriodicalIF":1.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144571110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining a species’ ideal zoo diet remains challenging, necessitating assessment of an animal’s responses to their diet to establish best practices, including any effects on behaviors. This study investigates the behavioral responses of five female giraffes (<em>Giraffe camelopardalis</em>) to browse from four tree species (willow, <em>Salix caprea</em>; hawthorn, <em>Crataegus monogyna</em>; hazel, <em>Corylus avellana</em>; oak, <em>Quercus robur</em>). This study aimed to assess the effect of browse species on giraffe activity and to identify which of these species was most associated with performance of key welfare indicators. Given this species’ adaptations to foraging on spinose (i.e., thorny) trees, we predicted that hawthorn would have the largest effect on giraffe behavior. Focal sampling of individual giraffes was conducted, with equal repetitions for each browse species, across spring and summer 2021 and 2022 at Marwell Zoo. Giraffes were observed for an hour with browse, followed by an additional hour after a 30-minute pause to quantify post-browsing behaviors. Results suggest that willow increased overall browsing time, while oak elicited prolonged interaction with initial browse branches. Willow promoted the highest bark stripping and bite counts, while oak and willow increased time ruminating. Contrary to expectation, hawthorn, with its thorny defences, did not significantly extend browsing or rumination. Social context also influenced browsing behavior with heightened browsing activity occurring when giraffe browsed with other species present.

This procedure is known to be a major source of stress especially for cats. The purpose of this study was to evaluate the clinical relevance of rectal temperature measurement in healthy cats with signs of marked stress during a routine veterinary appointment. We hypothesized that since higher temperatures would be mostly found in cats with moderate to marked signs of stress, veterinarians would not change their clinical approach in these cats. A user-friendly Simplified Feline Stress Scale (SFSS) was developed. Its trial was the main objective of the pilot study (part 1) designed for 100 cats. Data surrounding temperature measurement in cats was documented (value of rectal temperature, time of restraint needed, and various factors related to cats and clinical staff such as age, sex and more) to evaluate potential associations with stress. Then, during a large-scale study (part 2) of 678 cats the previously validated SFSS was performed by clinical staff in 11 veterinary establishments concurrently with temperature measurements. The final portion of the study (part 3) was an online survey completed by veterinarians across the province of Quebec in order to document the reasons a high rectal temperature in a healthy cat might motivate a change of therapeutic plans. This study showed that veterinary appointments were associated with moderate to marked levels of stress in 62% of feline patients. Agreement between clinical staff-assessed and experienced observer-assessed SFSS scores during the temperature measurement was perfect in 74% of cases and even higher when clinical staff had received previous behavioral training. The majority of calm cats with low signs of stress were under 6 months of age. No change in the therapeutic plan was deemed necessary in stressed cats with an abnormal temperature if they were healthy. According to the online survey, 80% of veterinarians would not modify their treatment plan in such situations. The results of this study suggest that rectal temperature measurement in healthy cats during routine examination is not necessary and could be avoided in highly stressed feline patients.</div></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"80 ","pages":"Pages 1-9"},"PeriodicalIF":1.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144548726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to assess the influence of maternal rank on the hierarchical rank of captive collared peccary offspring using social network analysis. By examining aggressive and affiliative interaction data, we generated hierarchies using David's Score and calculated social network indices (centrality, strength, and affinity) to identify individuals' roles in social stability. These analyses were performed with the SOCPROG program. Findings indicated that maternal rank did not significantly affect offspring rank. However, mothers demonstrated higher association index values compared to their offspring. We concluded that the peccary hierarchy is predominantly established through maternal associations rather than offspring interactions, suggesting that offspring rank positions may result from adults' high tolerance towards young individuals.</div></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"80 ","pages":"Pages 49-56"},"PeriodicalIF":1.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This open-label, uncontrolled trial—without a placebo—evaluated the potential anxiolytic effects of these extracts in 20 mixed-breed dogs exhibiting clinically relevant anxiety, as determined by owner-completed behavioral questionnaires. Dogs were assigned equally to two groups (VO and HE, n = 10 each) and received a daily dose of 1000 mg per 10 kg body weight over a 4-week period. Assessments included EEG recordings from frontal, temporal, and central brain regions (analyzing delta, theta, alpha, and beta frequency bands), neurochemical analyses of serotonin, dopamine, and cortisol, and standardized behavioral surveys conducted at baseline and after treatment. The results indicated modest improvements in certain owner-reported behaviors, particularly reductions in fear and roaming. Within-group analysis showed statistically significant improvement in 4 behavioral signs in the VO group and 2 signs in the HE group out of the 15 assessed. However, no statistically significant differences were found between the groups, indicating comparable behavioral outcomes across treatments. EEG analysis revealed that HE treatment was associated with reductions in theta and select alpha power in frontal and temporal regions, while VO exhibited less pronounced effects. Neurochemical findings suggested that HE may reduce plasma serotonin levels and VO may decrease dopamine levels. Both treatments were well tolerated, with no adverse events observed. Although these preliminary findings suggest that VO and HE extracts might modulate neurophysiological and neurochemical markers related to anxiety in dogs, further controlled studies are needed to establish clinical relevance.</div></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"80 ","pages":"Pages 57-68"},"PeriodicalIF":1.3,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144579934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Behavioural issues are one of the most common reasons, along with personal problems and financial difficulties faced by owners.

Veterinarians are often contacted too late, as a last resort. A questionnaire consisting of 56 questions (in paper or online version) has therefore been created to help veterinarians detect behavioural issues in dogs early. It had to be sufficiently short but also exhaustive to be efficient to detect a behavioural problem during a preventive medicine consultation. 290 responses were collected. Among the respondents, some dogs were consulted by one of the participating veterinary behaviourists. These dogs were then categorized into 4 groups: fearful, impulsive, stable or with absence-related problems. A statistical study using Partial Least Squares Discriminant Analysis, Variable importance in Projection Scores and Receiver Operating Characteristic was conducted. 20 questions were selected for the final questionnaire. The misclassification rate is 30% for the entire model, with a rate of only 5.3% for stable dogs. A scoring system was proposed to provide values for each category and appears consistent with the tested dogs. To our knowledge, this is the first questionnaire allowing practitioners to detect behavioural issues early.

A statistically significant difference in lymphocyte count was observed between the two groups. However, no stress-related leukocytosis, hyperglycemia, hypokalemia, or elevated lactate levels were detected in any of the cats, regardless of gabapentin use.
