Pitbulls used to be known as "nanny dogs" for their temperament (they score above a golden retriever in temperament!). Pits are NOT naturally vicious animals and they DONOT have lock jaws. Learn your facts before you judge. It's how you raise them. ANY type of dog that you abuse, taser, beat and never show love towards will become vicious over time. Punish the owners and have stricter laws about who can own them. don't punish an innocent dog!
