I have seen aggressive dogs of all breeds. Some more so than others. My family have owned pitties and never had a problem with them. I have never owned one because frankly I don’t trust them. I agree with the comment that they seem to be more aggressive when are 2 or more together. I prefer calmer, easier going furkids. I wouldn’t trust a pit with kids or my other dogs though I have seen them be perfect gentleman and ladies with children and other dogs. People have the right to choose the breeds of dogs they want. They also have the responsibility, legal and social, of the dog. That doesn’t help the ones who get bitten, mauled or killed, person or other pet, by their dog. The dog should be euthanized for a severe mauling or killing of human or animal. (Unprovoked)
