RESUMO

Caracterizaram-se as agressões por cães, o perfil das vítimas e dos agressores e as circunstâncias desses acidentes. Calculou-se a amostra aleatória a partir de 20 mil notificações/ano de agressões por cães e realizaram-se 594 entrevistas telefônicas. A maior frequência de agressões ocorreu no sexo masculino, faixa etária de cinco a 14 anos. Lesões leves representaram 80,4%. As profundas (19,1%) ocorreram por cães de porte médio seguidas pelos de grande porte. A maioria dos cães era macho adulto, porte médio. Dos entrevistados, 52,5% desconheciam a condição reprodutiva; 41,0% dos cães não eram esterilizados e 6,4% eram esterilizados. Cães sem raça definida (SRD) provocaram 48,4% dos acidentes, e 57,6% das agressões ocorreram em locais privados. Em 56,2% das agressões, as vítimas eram moradoras do imóvel ou pessoas conhecidas. Com animais não conhecidos a agressão mais frequente ocorreu na rua, 30,8%, e 67,5% dos donos permaneceram com os animais. As agressões foram resultantes da interação homem-cão e devem ser estudadas para se identificarem os possíveis comportamentos que desencadeiam a agressão pelo animal.

ABSTRACT

This study aimed to characterize aggression by dogs, the profile of victims, and perpetrators and circumstances of these accidents. Understanding the interaction between victims and aggressive dogs contributes to preventing aggression. The random sample from 20.000 reports / year of attacks by dogs was calculated and 594 telephone interviews were conducted. The highest frequency of assaults occurred in males from 5 to 14 years of age. Non-severe injuries represented 80.4%. Deep lesions (19.1%) were caused by medium and large dogs. Most dogs were medium size adult males. Of the respondents, 52.5% were unaware of the reproductive condition, 41.0% of dogs were not sterilized and 6.4% were sterilized. Dogs without defined race caused 48.4% of accidents and 57.6% of assaults occurred in private places. In 56.2% assault victims were residents of the property or known people. Aggressions from unknown animals were more frequent on the street (30.8%). 67.5% remained with the animals' owners. The attacks were the result of interaction between man and dog and should be studied to identify which human and canine behaviors can trigger accidents, to understand how the interaction occurs in different situations whithin the same household, with acquaintances, on the street, and with unknown animals. Educational approaches detailing risks and prevention methods are essential.
