If anyone has ever watched a match between 2 Pits that is hardly if any blood. I DO know that even though a Mastiff is larger and people would think them to have more jaw power than a Pit, a Mastiff bites and then releases mostly while a Pit usually holds strong. That is what I mean by bite strength. A Pit doesnt have locking jaws, just has the muscle power and will to HOLD ON. They dont have the sharp teeth as other breeds and they dont bite and shred like other biting caused by other breeds. They Bite and hold, instead od trying to tear and shred. My father had told me that a many fights he had seen resulted in little or no blood. That the dogs grabbed and held on when they got a good bite. That sometime the dogs are seperated and re-released. They werent out to rip the other dog apart. There is no growling, no barking etc when in the Pit. Bruising, broken bones, deep puncture wounds are all the result of a Pit fight. Like I said I didnt base my opinion on facts, but I ASSUME the pit Bull jaw strength is stronger than any breed just because they can HOLD for LONG periods of time unlike other breeds, and because their jaws are wide and allow a good bite and then hold on. Ill put it this way then, they have some of the STRONGEST jaws in the canine world. better? lol My opinion of couyrse, not a fact.
