More golden retrievers bite humans then pit bulls do, and a little dog is on average more likely to bite then a large dog. The only reason you don’t here about those attacks is because the media chooses to focus on one breed. They did the same thing with dobermans and other breeds. Even going so far as to make the breed standard not even what the dog looks like naturally, for example: cropped ears and docked tails. I have never met an aggressive pit bull, and that is saying something because I volunteer at animal shelters filled with them in a place were so many gangs breed dogs to fight and then dump the poor creatures on the street when they have no use for them any more.
