October is Pit Bull Awareness Month!
Fact or Fiction? Pit bulls have locking jaws, so once they bite down, they don't let go.
Fiction. A study out of Presbyterian College by Jesse M. Bridgers III titled "Mechanical Advantage in the Pit Bull Jaw" examined 49 skulls of varying breeds of domestic dogs, three of which were from pit bulls. Conclusion: "After graphing and analyzing the derived ratios, I have found no evidence of mechanical advantage in the pit bull compared to other domestic breeds of dogs". A 2003 study by T.E. Houston titled "Bite Force and Bite Pressure Comparisons of Humans and Dogs found " There is nothing out of the ordinary in the jaw structure or anatomy of the bull breeds". Dr. I.Lehr Brisbin of the University of Georgia has stated under oath "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". The Houston study also disproved the myth that pit bulls have 1600 pounds per square inch of bite pressure. Both Rottweilers and German Shepherds were shown to bite with greater force that pit bulls.
Nearly all dogs of all breeds are capable of biting and holding on with surprising tenacity. For a free demonstration, stop by the clinic and try to extract a Greenie from Grendel's mouth. You will tire long before our geriatric dachshund does!
