oh oh I read a study answering that.

It depends on behavior. They found high correlation between breed and how many time they turned around before laying down. Certain common trip like sit or come. But not aggressive behavior. They highest correlation for that was back ground. Dog from the streets or abusive backgrounds. Followed by a small correlation with genetics, which is not the same as breed.

Breed did have anything to do with aggression. Also most people can’t tell a pitbull from other dogs, and studies that look at dog attacks only rely on the victim just saying what breed attacked them
