The following quote was sent to me from Dr. Howard Evans, Professor Emeritus, College of Veterinary Medicine at Cornell University, Ithaca New York. We were colleagues in the veterinary college for four years. He is the author of the textbook, ANATOMY OF THE DOG, (the world's definitive work on the anatomy of the dog). His statement was in a letter addressed to me on March 26. 2002. His quote was: "I have spoken with [Dr.] Sandy deLahunta (the foremost dog neurologist in the country) and [DR.] Katherine Houpt (a leading dog behaviorist) about a jaw locking mechanism in pit bulls or any other dog and they both say, as do I, that there is NO SUCH THING AS "JAW LOCKING" IN ANY BREED.
We all agree that the power of the bite is proportional to the size of the jaws and the jaw muscles. There is no anatomical structure that could be a locking mechanism in any dog." As a Professor Emeritus from the College of Veterinary Medicine at Michigan State University, I agree completely with their conclusion. and as to bite force here are the facts
Dr. Brady Barr of National Geographic (Dangerous Encounters: Bite Force, 8pm est 8/18/2008) - Dr. Barr measured bite forces of many different creatures. Domestic dogs were included in the test.
Here are the results of all of the animals tested:
- Humans: 120 pounds of bite pressure
- Domestic dogs: 320 LBS of pressure on avg. A German Shepard American Pit Bull Terrier (APBT) and Rottweiler were tested using a bite sleeve equipped with a specialized computer instrument. The APBT had the least amount of pressure of the 3 dogs tested.
- Wild dogs: 310 lbs
- Lions: 600 lbs
- White sharks: 600 lbs
- Hyenas: 1000 lbs
- Snapping turtles: 1000 lbs
- Crocodiles: 2500 lbs
