"That includes climbing into your lap, digging out of an inadequately fenced yard, competing in canine agility trials or just following you around the house," Reynolds said. "Intelligence, determination, trainability and a good sense of humor are the hallmarks of the breed."

Pit bulls may be crazy about people, but that's not always the case with other dogs. "They're terriers, and like all terriers, aggression towards other animals is not uncommon," she cautioned. "And like all dogs, pit bulls and their owners need training to become a good people/dog ambassador team."

The reality is that even pit bulls from known fighting backgrounds, covered in fight scars, often turn out to be complete sweethearts -- even with other dogs. One of the best-known examples of this is Hector, a squirming, face-kissing bundle of love who is a certified therapy dog today, but started out his life as a fighter at Michael Vick's Bad Newz Kennels.
