Dogs are what, us humans make them to be. Some breeds have been bred explicitly to be aggressive, like pit bulls and others to be decorative. But mostly, aggressivity in dogs is an education matter. Instead of banning dog breeds, lets educate them and their masters : Education of dog owners can address several issues:
(1) understanding breed profiles may assist owners in
selecting the appropriate dog for their lifestyle and train-
ing abilities, (2) convincing owners to seriously consid-
er the sex and reproductive status of their dogs is impor-
tant because male and sexually intact dogs are more like-
ly to bite than are female and neutered dogs, and (3)
teaching owners about the importance of socialization
and training may decrease their likelihood of owning a
dog that will eventually bite.
