This article will provide advice on how to raise a pitbull right and prove the stereotype wrong. Over the years, the American Pitbull Terrier has gained a bad reputation as a naturally aggressive breed of dog. This mostly comes from the fact that before the dogs were ever brought to America they were bred to fight bulls and once bull baiting became illegal, they were sent to fight one another. The thing is, these dogs only fought to please their masters, really. They are no more aggressive than any other breed of dog when they receive the proper training.
