Risk factors for human‐directed aggression in a referral level clinical population

Abstract

Risk factors for human-directed aggression were investigated using retrospective analysis of data from a referral-level clinical behaviour population in the UK. A sample of 200 cases involving human-directed canine aggression and 200 control cases involving no instance of human-directed aggression were selected at random from a population of 746 cases. The final model suggested that clinical cases with human-directed aggression were significantly younger than those presenting with other undesired behaviours (P=0.008) and that male dogs were 1.4 times more likely to be aggressive towards human beings than female dogs (P=0.019). Dogs were 1.7 times more likely to be aggressive towards people if they had attended more than five puppy classes than if they had never attended puppy class (P=0.015) and that dogs were 2.8 times more likely to be aggressive towards human beings if there was another dog between 0 months and 24 months of age in the home (P=0.004). These factors only account for 7 per cent to 10 per cent of the variance between the human-directed aggression population and the control population, but factors such as attendance at puppy classes and numbers of dogs in the household suggest the need for longitudinal studies to investigate temporal relationships.

Comprehensive representation of health-related phenotypes in one million dogs using topic modelling of electronic health records

“…Unsurprisingly, consultations relating to male neutering and female neutering and mammary disease were strongly biased, but additionally, key known predispositions were immediately surfaced, including seizures in male dogs [8], grass seed injury in male dogs [2], urinary tract disease in female dogs [4]. Additionally, consults describing dog aggression were more common in male dogs, in line with previous studies that indicate male dogs are more prone to human-oriented aggression [16]. Critically, a number of female dog narratives were labelled with the topic with keywords including testicles and castration.…”

Relação Da Agressividade Canina Com O Medo

“…No presente estudo, observamos que a prevalência de agressividade acima da média esteve associada com cães machos, castrados, de raça pura e de porte pequeno, especialmente aqueles com medo acima da média, achados também suportados por outros estudos (5,(7)(8)(9)(10). A agressividade demonstrada por alguns cães apresenta causa multifatorial, seja em nível de indivíduo ou contextual.…”

Managing the Risk of Aggressive Dog Behavior: Investigating the Influence of Owner Threat and Efficacy Perceptions

“…The majority of research regarding aggressive behavior in dogs has typically focused on the behavior of the dog itself, rather than exploring the perceptions and decisions of owners who are attempting to manage such situations (Casey et al., ; Casey, Loftus, Bolster, Richards, & Blackwell, ; Lord, Loftus, Blackwell, & Casey, ). This is despite the fact that such decisions are likely to have a fundamental impact on the dog's resulting behavior (Blackwell et al., ; Casey, Twells, & Blackwell, ).…”
