Emotions and Dog Bites: Could Predatory Attacks Be Triggered by Emotional States?

SIMPLE SUMMARY: Dog bites are a worldwide problem that have severe consequences for both the animal and the victim involved in the incident. Epidemiological studies have analyzed the victim features, the characteristics of biting dogs and the context in which attacks occur. Little is known regarding the role of emotions in predatory attacks toward humans and conspecifics in dogs. This paper aims at proposing the potential involvement of emotions for the expression of predatory motor patterns. It is suggested that the reporting of dog biting episodes needs to consider this crucial factor, which is fundamental for providing a realistic and reliable picture of the dog bite phenomenon. ABSTRACT: Dog biting events pose severe public health and animal welfare concerns. They result in several consequences for both humans (including physical and psychological trauma) and the dog involved in the biting episode (abandonment, relocation to shelter and euthanasia). Although numerous epidemiological studies have analyzed the different factors influencing the occurrence of such events, to date the role of emotions in the expression of predatory attacks toward humans has been scarcely investigated. This paper focuses on the influence of emotional states on triggering predatory attacks in dogs, particularly in some breeds whose aggression causes severe consequences to human victims. We suggest that a comprehensive analysis of the dog bite phenomenon should consider the emotional state of biting dogs in order to collect reliable and realistic data about bite episodes.
