https://www.friedlrichardson.com/dog-attacks-by-breed/ I own 3 and they will bite your ass if you walk into my house univited ive taught them to, best alarm system ever that being said outside my home theyll play with any other dog that decides to come wandering thru the woods but they will fight from time to time usually when a bitch is in heat . if you have a pitbull own a break stick and keep it close and know how to use it because when they lock down on something they lock down on it you literally have to choke them unconscious or pry their jaws apart. pitbulls are game animals they have a drive to kill things for sport namely other dogs and animals. but they were put down if they showed human aggression in any form back in the days when a handler had to break them up if one got bit it was a dead dog that bred human loyalty. its to bad some thugs always seem to exploit that loyalty in them and turn them into viscous animals. thats what i think is responsible for 90% of the attack someone want a "badass" dog they keep him chained up and abused and praise him when he shows violent tendencies one day he gets out and bites someone. its more the owner than the dog give me a labrador puppy for about 6 or 8 months ill show you the first attack lab youve ever seen if i wanted to train it that way
