Contrary to myths propagated by the media, human aggression occurs in all dog breeds. For your information, pit bulls test well above average in temperament evaluations. Each year, the American Temperament Testing Society holds evaluations across the country for dog breeds and gives a passing score of 85.5 percent to pit bulls. To put these figures into context, the combined passing rate of all breeds was score of 81.6 percent. The collie, an icon of obedience, passed at a rate of 79.4 percent, and the beloved golden retriever scored at 84.2 percent. As you can see, by these measures, the pit bull breeds make fabulous family pets. It is important to understand the breed's nature, to provide a structured environment, and to establish a positive leadership role. In order to do so, pit bull owners must understand the original purpose of the breed, respect its limits, and help it fulfill its tremendous potential. This is sound advice for dog owners of any breed. The American Pit Bull Terrier, or the AmStaff, is certainly not the right pet for everyone. Being a powerful dog, it will require sufficient and adequate control. An insecure person who wants only an aggressive dog to bolster some personal human inadequacy should never become an owner of one of these dogs. An uncaring or negligent person should not buy an AmStaff or an APBT (or any other dog for that matter).
