The following quote was sent 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.
Pit Bulls have a 1800 PSI Jaw Pressure. Wrong again. Working with author Karen Delise (Fatal Dog Attacks) we have researched the references used for this data and have found there is no factual research to support this claim. This myth stems from an article published in the 1989 The Journal of Trauma "Mauling by Pit bull Terriers: A Case Report" by Bret R. Baack, M.D., John O. Kucan, M.D., Gerland Demarest, M.D and E. Clyde Smoot, M.D. On Page 519 it states: "Pit Bulls bite with greater force than most dogs (up to 1,800lb/in2) (4).
Reference (4) cited for this fact is: "Dog bites in children: Epidemiology, microbiology, and penicillin prophylactic Therapy but Douglas A. Boenning, M.D., Gary R. Fleisher, M.D., and Joesph M. Campos, PhD.
However, neither the topic of bite pressure nor pit bulls is addressed or even mentioned throughout the entire article.
This case report is promoted by many people as fact, yet it's not substantiated anywhere.
On the other hand, here is scientific evidence proving this myth is an urban legend:
Dr. Brady Barr of National Geographic (Dangerous Encounters: Bite Force, 8pm est 8/18/2005) – 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
Pit Bulls are born to be mean. Not True! Pit Bulls like all other breeds, are not born inherently mean or bad! They can, like any other breed, become mean through lack of training, abuse, neglect and irresponsible ownership and breeding.
(From ACF) There is no scientific proof that Pit Bull's, or any other breed of dog is dangerous. The Foundation's collective experience and research has found the American Pit Bull Terrier is a "terrier." All terriers have animal prey
drive, but this does not make them dangerous or vicious. The Pit Bull type dog comes from Europe and evolved from some Mastiff based breed such as with some Bulldog blood either in a pure form or to a variation of any of the many terrier and hound groups beginning with the now extinct Black and Tans Terriers and Olde English White Terriers. English and Irish immigrants imported the dogs. Unfortunately, it was discovered in the late 1800's that if trained, the dogs could be used in the inhumane sport of dog fighting. Due to federal laws passed in the 1970's prohibiting dog fighting fewer dogs are now trained for the illegal sport.
The American Pit Bull Terrier is shown in the American Kennel Club (AmStaff), United Kennel Club, American Dog Breeders Association, Canadian Kennel Club, and the American Rare Breed Association . The American Pit Bull Terrier is shown in the conformation and obedience ring. This breed competes in weight pull events in the ADBA, UKC and International Weight Pulling Association. The American Temperament Test Society (POBox 4093, St Louis, and MO 63136 Phone 314-869-6103, in the 24 years of testing over 185 breeds of dog, rates the Pit Bull at 83.1%. This is higher than the national average for all other breeds of dog. This means the Pit Bull has the best overall temperament. The American Pit Bull Terrier also rates high in the Canine Good Citizens Test. The Pit Bull is used for Search and Rescue and as a Therapy dog. Our Foundation uses them along with other breeds for bite prevention and responsible ownership classes in the Washington School
Districts. Two US Presidents owned Pit Bulls and countless famous people own them. In our country more families own the Pit Bull than any other dog breed in existence. (WAFAmicus Alabama 2002)
From American Canine Foundation:
Since 1936 there have been an estimated 4.8 million registered American Pit Bull Terriers, American Staffordshire Terriers and Staffordshire Bull Terriers that have been selective bred for companionship and conformation dog shows. These dogs are not bred for dog fighting and HSUS estimates 200,000 thousands Pit Bulls are used for illegal activity. There is no proof that the 4.8 million APBT's are included in this figure, because the registries AKC/UKC/ADBA that register these dogs prohibit illegal dog fighting. If it could be proved that any of the registered APBT's were involved in illegal activity, it would be less than 4 percent out of 4.8 million. There is an estimated 52 million dogs in the United States and the American Pit Bull Terrier takes up 9.6 percent of the dog population and that does not count unregistered ones. There is no such dog called a Pit Bull Type Dog, it would be a mix breed. (ACF2003)
