Do APBTs really have 1600 psi biting pressure and locking jaws?
No, they do not have either. 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 comparision 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.” Futhermore, 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.
