Trait matching, or the tendency of individuals to seek partners who share similar biological and behavioral traits, could enhance the benefits of play by allowing mammals to accurately and reliably predict each other’s behavior. As a result, this could lead to smoother social interactions. To test this idea, we explored the preferences of domesticated dogs during intraspecific open play bout sessions, as dogs are known for engaging in high levels of social play even into adulthood. In line with other studies on intraspecific play in dogs, we examined whether trait matching affected play duration and the average distance between dogs. We specifically predicted that trait matching would lead to longer play times and closer average proximity. We analyzed the effects of both biological (size, age, sex) and behavioral (head-to-head contact, head-to-tail contact, rearing history) traits on duration and distance. We did not find any evidence to support our predictions. Given the null results of our study and the recent mixed findings from other research on intraspecific dog play, it seems that other biological and behavioral factors (such as energy levels and personality traits) may play a role in trait matching. This, in turn, could influence the average duration and distance of play, although additional research is needed to confirm these ideas.</div></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"85 ","pages":"Pages 7-15"},"PeriodicalIF":1.6,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147387523","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}

Tapirs showed avoidance or defensive responses to direct contact, including sudden jerks, high-pitched vocalizations, and withdrawal movements. Rat activity decreased markedly on the night when a stray cat was recorded, suggesting predator avoidance. While the precise nature of this interaction remains unclear, it raises important welfare concerns for captive animals. We recommend routine nocturnal monitoring, proactive rodent control, and improved enclosure management.

Medical records from a veterinary behavioral referral service were reviewed for dogs prescribed venlafaxine between May 2016 and February 2021 with a presenting complaint of aggressive behavior, a diagnosis of one or more underlying behavioral disorders, and at least one follow-up contact (n = 114).

A higher dosage was associated with increased odds of treatment efficacy (p = 0.007).

Higher dosages were also significantly associated with higher odds of adverse events (p < 0.001), and adverse events resolved with dosage reduction or discontinuation.

When measuring social bonds among animals, researchers have often relied on spatial proximity measurements, and recently, there has been a movement toward using AI-based approaches to improve accuracy in these assessments. However, such approaches have not yet been applied to the study of domestic cat affiliative behavior and social bonding, despite their large degree of social flexibility. In our current study, we use AI-based computer vision systems to investigate the relationship between social context (affiliative vs. non-affiliative), sex composition (female-female, mixed-sex, male-male), and spatial proximity during intraspecific cat facial signaling interactions. Based on our understanding of social bonding in domesticated cats, we developed two testable predictions: (P1) that cats will be closer during affiliative facial signaling interactions than during non-affiliative ones; and (P2) that adult sex composition affects communicative proximity, with female–female dyads showing the closest proximity, followed by female–male/male–female, and finally male–male dyads. Our results supported P2 but not P1. Interestingly, cats showed significantly greater spatial proximity during non-affiliative facial signaling interactions than during affiliative ones.
