I think it is what they are capable of that’s the issue. Folks like to throw out numbers about other breeds and how many people were bitten by this breed of dog or that type dog but the problem still is what these dogs were breaded for, blood sports in the United Kingdom in the 1800 to fight and kill. They have a high tolerance to pain and the pounds for pressure that they can exert with their jaws. Just ask Michael Vick how nice these dogs can be. I’m sure he has some stories to tell.
