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 [other] breed of dog. There is absolutely
Not 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,
Says Dr. I. Lerh Brisbin of the University of Georgia (from the ADBA
Booklet, “Discover the American Pit Bull Terrier.)
Tests that have been done comparing the bite pressure of several breeds showed pressure PSI (per square inch) to be considerably lower than some wild estimates that have been made. Testing has shown that the domestic dog averages about 320 lbs of pressure per square inch. Recently Dr. Brady Barr of National Geographic conducted a comparative test between a Pit Bull, a Rottweiler, and a German Shepherd. The Pit Bull had the LOWEST PSI OF THE THREE.
