Dispelling some myths about Pit Bulls:

-Is it true that Pit Bulls can lock their jaw?
The infamous locking jaw is a myth. The American Pit Bull Terrier and related breeds are physiologically no different from any other breed of dog. All dogs are from the same species and none have locking jaws. Dr. I Lehr Brisbin of the University of Georgia states, "To the best of our knowledge, there are no published scientific studies that would allow any meaningful comparison to be made of the biting power of various breeds of dogs. There are, moreover, compelling technical reasons why such data describing biting power in terms of 'pounds per square inch' can never be collected in a meaningful way. All figures describing biting power in such terms can be traced to either unfounded rumor or, in some cases, to newspaper articles with no foundation in factual data." Furthermore, Dr. Brisbin states, "The few studies which have been conducted of the structure of the skulls, mandibles and teeth of pit bulls show that, in proportion to their size, their jaw structure and thus its inferred functional morphology, is no different than that of any breed of dog. There is absolutely no evidence for the existence of any kind of 'locking mechanism' unique to the structure of the jaw and/or teeth of the American Pit Bull Terrier."

-Are Pit Bulls naturally aggressive towards humans?
While many Pit Bulls do tend to be aggressive towards other DOGS (as are most terriers), the normal, well raised Pit Bull has NO human-aggressive tendencies! In fact, human-aggression was actually bred out of the breed. The majority of Pit Bulls are affectionate, intelligent, trainable dogs. In fact, the highest obedience trial record of all time is held by an American Pit Bull Terrier named Maddy!

-Can Pit Bulls "turn" on people?
In fact, no breed of dog does. Dog aggression is nearly always preceded by some kind of warning, and there is always a reason behind the attack. However, many inexperienced owners do not recognize the dog's behavior as aggression, or refuse to acknowledge it as a warning sign. The only exception I can think of is Springer Rage, a rare and controversial neurological condition that manifests itself as a spontaneous attack, followed by confusion, and then a return to normal behavior. Pit Bulls are NOT prone to this condition. There are individual dogs of any breed that may be more aggressive to others.
