A good and bad reply.
The hamstring information is valid and very good advice. You got into the mind of the dog with that. Just be VERY careful, and faster than you ever thought you could be.
The MYTH about pitbulls’ being able to lock their jaws is just that, a MYTH. They have very strong jaw muscles, but other than size and the musculature, there is absolutely NO difference between the jaw structure of a pit bull and a chihuahua.
Ask any vet.
I’m not saying it’s a true “lock”, but the jaw muscles of a Staffordshire are really impressive and those muscles will not go lax quickly enough to save another dog who he has in a death grip even if you cut his throat.
That is what I mean by you will still have to pry his jaws apart.
And yeah, be prepared to lose the use of a hand for a while if you grab the hamstring of a medium to large dog. They are fast!
Actually, the best way to break a bite or fight is grab the aggressive dog by the hind legs, haul its arse off the ground as high as you can and “twist”, thereby kicking in its cerebral “gyroscope”.
NO dog likes being off balance and that will instantly snap its brain out of attack mode into self-balance mode.
The second key is *always* carry a small, spare leash in your pocket.
[mine is a 4 foot 3/8” flat braided nylon one...it wads up into a tiny ball in my pocket]
If there’s no one there to help you, quickly loop the spare leash around the waist of the attacked dog, tie it off to ~anything~ handy and then get -behind- the attacker and do the “wheelbarrow” maneuver while pulling away from the tethered dog.
It has the added advantage of keeping you *out* of bite reach of the “wheel-barrowed” dog.
