What breeds have locking jaws?

Among the breeds many believe to possess this quality are Boxers, American Staffordshire Terriers, and Bulldogs, though there are many other breeds considered to be "Pit Bull types" that also are credited with being members of the "locking jaw" family. The truth is there isn't a single shred of scientific evidence to support the locking jaw theory in any of these breeds or any breed at all. It is a myth which has become an urban legend. What is a locking jaw?

What is the difference between a dog's jaw and a dog's mouth?

What does differ is the amount of pressure a dog can exert , and this pressure is dictated by the size of the dog, not by the breed. Obviously, a "power breed" which is a rippling mass of muscle is going to have a stronger bite pressure per square inch than your mother's Pomeranian. It only stands to reason that a breed of size and strength will exert more overall force in an intended bite than a smaller breed. In the absence of any published scientific evidence to corroborate the locking jaw theory, to where does this urban legend trace its origins? It's hard to say definitively, but there are a few possible explanations. It is a possibility that the myth originated with dog fighters themselves. Men involved in this type of operation may have boasted of the powerful jaw strength of their champion fighters and even used the terminology that led to the eventual use of the term "locking jaw" as we know it today. A dogfighter may have gleefully reported that his dog "locked onto" another dog, and through repetition, misunderstanding, and misuse, "locking jaw" became the new phrase. This may well have been a point of pride for the owners of these dogs though there isn't even an ounce of truth to the phenomenon.#N#Another theory suggests that this term is derived from the earlier practice of "bull baiting." Bull baiting was encouraged in breeds such as Bull Terriers, American Staffordshire Terriers, and other "game" dogs. Its sole purpose was the sport, and it was bloody, harmful to the bulls, and cruel. The most successful bull baiting dogs possessed the singular focus to bite down on their opponent and refuse to release the bite until their opponent submitted or died. This was not due to any locking ability but rather to the tenaciousness of the dog. The dog fighter valued the dog's stubbornness highly. This quality earned him lots of money!
