“Kay, you're right about bull terriers, just the same as any breed of dog. If an animal is treated with kindness, respect and love, it responds in kind. Unfortunately some of the hateful little yobs out there don't know the meaning of those words and that's when a dog becomes dangerous. A bull terrier is "built for trouble" and by it's physical attributes is more likely to be chosen by such yobs over a chihuahua to show how "tough" the owner is.
There can be little doubt how the dog the subject of this new item came to be the way he is.”

“That's a Japanese Akita she-dog. (Stupid censorship).”

“The only time that I've had one of my dogs seriously attacked by another dog (he might have been killed), the offending dog was a Japanese Akita *****. People obsess about bull terriers, but most of them are friendly and not kept as status symbols.”

“It really does not matter if these dogs can lock there jaws or not unfortunatly because they are seen as a status syimbol but a group of men who need them to make them men they are either not trained or trained for the wrong reasons, they should not be allowed out on public with out a nuzzel and nutered , any found with out should be put down straight away . All dogs should be licenced , nutered [ apart from special licenced dogs ] chipped and there owners should have insurance . Any dogs found not not chipped immediatly put down”

“Matt, it's a good way to stop you biting your nails.”

“A very firm grip translates as locked on for a bull terrier. They don't fight like other dogs which in the main is loads of snarling and snapping. Their instinct when they get a good grip is not to let go, that strikes me as 'locking on' although it may ultimately be a semantic argument.

As to inserting my digit up a mad dogs butt, I have to say that I've never considered it and I'm still trying to work out how i'd get my hand close enough to that end of the animal without bringing my face into the bite zone just in case it did actually decide to release its lock on my leg. Personally I think I'll stick with the tried and tested method of a swift kick in the head and/or whatever I may espy as dangling down.
Thanks for the advice but I think I'll ignore it.”

“TBH - the last thing I would do is stick my thumb up a dog's bum. Not only will you annoy the dog even further, but your thumb won't smell very nice. You could try to remove its air supply by covering its snout - if it has something in its mouth it will soon let go of it to breathe.”

“Evidence on the net says that it's an urban myth that bull terriers can lock their jaws. Try Googling a question such as 'Is it true that pit bulls lock their jaws when they bite?' You'll see that dog experts say that it is simply a very firm grip.

By the way, I've heard more than one expert recommend that, if you are being bitten by a dog that won't let go, a human thumb up the rectum will make any dog release its grip. Not very nice, but then neither is being chewed by a mad dog.”

“@chris2308- the quote i have just copied and pasted is from one vet to another vet.... please also note what thet say about the bite pressure from the PB compared to a GSD and a Rottie. In short the EXPERTS who have studied the anatomical features of canines clearly state that the dogs cannot physically 'lock' their jaw! The pure muscular strength gives us the impression it locks!
You seen any snow yet :-p”

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
