This is one of the most rediculous bits of nonsense that surrounds this maligned breed.
Listen. Pit bulls (of any variety) DO. NOT. HAVE. LOCKING. JAWS. Period.
Are they tenacious bastards (
)? Yes.
Do they have extremely powerful, muscular jaws? Yes.
Do they like to fight? Right down to the bottom of their game lil hearts.
Do they have some sort of special locking mechanism in their jaws that no other breed has? No. They don’t.
One of the reasons that it’s so hard to break them from a bite is the fact that they are absolutely driven to fight–it’s what they’re bred for, the same way a border collie is absolutely driven to herd. They want that hold more than food, or a bitch in heat, or anything that exists. Also, their face is comprised of very bulky, very powerful muscles. They do not have any sort of locking mechanism in their jaws.
In regards to the person who compared a pit bull’s bite strength with that of a panther, that’s another silly misnomer. I’ve heard over and over again that a pit bull has a bite pressure of 1,500 pounds psi, or 3,000 pounds psi, or whatever, or that a pit bull has a bite stronger than [insert scary animal here], but any objective system with which to measure a dog’s bite pressure has not been invented yet. This is partially because the strength of a dog’s bite is going to vary from day to day and activity to activity. Sport trained or personal protection dogs vary hugely in their bite pressure from decoy to decoy, day to day, event to event. It depends on how driven the dog is to bite, whether it’s working in prey or defence mode, distractions, blah blah blah. Dog A might have a bite like an alligator one day, and the next he might not be nearly as worked up. Does that make sense?
That all having been said, I’ve seen this pit bull vs [insert wild animal opponent of choice] ‘debate’ sooooooo many times. Here’s my take on it.
[disclaimer]I am not involved in dog fighting. I deplore any suggestion that fighting two animals for the purpose of entertainment or any other reason is a good thing. I have extensive knowledge of dog training and dog mentality. I have a lot of experience working with and around dog trainers and pit bulls. I love pit bulls. I’m a staunch defender of them, and in order to defend something, you’ve got to know your enemies. I know more about dog fighting than the average person, mostly due to being involved in pit bull rescue.[/disclaimer]
Pit bulls love to fight. Once a game pit is exposed to dog fighting, it’s all that dog wants in the entire universe. Again, the same way any other breed of dog has a passion for the activity it was bred to do. They fight because it makes them happy to make another dog dead.
Wolves fight for survival. Food, procreation, dominance. Even dominance scuffles are rarely more than a lot of vocal bluffing and posturing and maybe a few snarky snaps. One wolf submits, end of discussion. Fighting wastes energy. Wolves do not participate in combat for the sake of combat. A wolf, just like any other wild animal faced with an illogically aggressive adversary, is more than likely to turn and run once it becomes apparent that the fight is useless. What I’m saying is, if the wolf didn’t have a very compelling reason to fight in the first place, it just wouldn’t happen. If you’re talking about putting the two in a dog pit, there would be zero reason for that wolf to fight the pit bull, and it probably wouldn’t last minutes.
There are many, many breeds of dogs that are wolf-like in mentality and structure. None of them are used for dog fighting. Why is this? Because the pit bull is absolutely engineered to be the ultimate fighting dog. Matched against a taller, less compact dog of any breed, the pit bull is generally going to dispatch his opponent in very short order. That low center of gravity helps a lot. Couple this with an almost complete lack of pain response, and there are few dog breeds that can consistently compare to the pit bull in the fighting pit. The Tosa Inu (~25 inches at the shoulder, weight range 130-150 pounds plus) is revered in Japan for ceremonial fighting. Not much competition for a game pit bull. This is not to say that no pit bull will ever be beaten by a dog any other breed, I’m only saying that no breed can ever consistently compare to a pit bull’s fighting abilities. If they did, pit fighters would use them.
I wish they weren’t so good at what they do. They’re the absolutely nicest people-dogs on the face of the planet. But they love to fight, and sadly way too many people continue to breed and use them for this purpose 
Peace,
