This is true. A pitbull is a respinsibilty to own. Just like a rottwieler or any other powerful dog. There is no lock but a pit has a 1800 psi bite. 1000 psi higher than any other breed. So although pits are good tempered and awesome animals. People need to understand how to own one and be responsible.
hey 88, i had always thought that was true about the 1500-2000 psi bite. but it turns out to be just another pit bull myth that was taken and ran with.
here is the info on the study...
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
