Don't believe what you see on animal channel ,no dog bites like a pit bull,period I know fellas in jap that have bothe tosa and pits ,I have also seen mastiff and bullmastiff try and take a rough boar ,they could not hang on or take the punishment .when the pit could hang and do damage plus could take what the big boar thrower at him ,I have even seen the pits get gutted by a boar and still hang on while you killed the hog .to sum it up there is no dog on earth like the American pit bull terrier.
