Pit Bull’s jaws do not lock, they do not have the most powerful bite among dogs (Rottweilers have that honor) they are not naturally human aggressive (in fact pit bull puppies prefer human company to their mother’s two weeks before all other dogs)
Pit bulls are a breed who have unfortunately gotton a bad reputation for being mean and aggressive. I believe all dogs need obedience training right from the start. When confined as a pup any breed will grow up to be unsociable. All dogs are good, and need our love and respect . If unwilling to put the time and effort into your pet, best advice is not to purchase one.
