There's a myth that pit bulls have "locking jaws" that seize up when biting. Though pit bulls have strong jaws and, like most dogs, will hold onto their prey after biting it, there is no evidence that a pit bull's jaws are anatomically different from those of other breeds.

Even fans of pit bulls acknowledge the breed is different from other dogs. "I tell people right off the bat, if you want a dog-park-type dog, a dog you can just run off-leash, please do not get a pit bull," Ami Ciontos, founder and president of the Atlanta Underdog Initiative, a pit bull rescue group, told CNN.com. "I want to make sure that whomever I adopt to is educated about the breed," Ciontos said. "We want to make sure they understand the stigma about the breed and that they are held to a higher standard."
