There's one major flaw in your "how to break up a dog fight" theory, hoss.
Who would have though; a dog bred to fight dogs attacking another dog when off leash!
I have had experience with this, had a tenant that had a pit mix; great with people but always attacked my Springer until I made him get rid of it. It even found a way to get out of a muzzle.
Pits do get lock jaw when on a “kill”; but if you pick the beast up by the tail (STRAIGHT UP), it will let go. At that point I recommend swinging it into a brick wall....
They DO NOT get lock jaw.

Gary Busey, on the other hand, does.
