A friend and ex Police force dog trainer told me that if a dog is aggressive/fighting the best way to safely stop it is to lift its hind legs off the ground.
This takes all the power out of the jaw.
A large dog attacked my little Patterdale some years ago.
I lifted the dogs hind legs, my son released our terrier and the dogs owner came and put it on a leash.
Phew!
Don’t rely on lifting a dog to make it release even a small dog like a terrier, trying to take a toy, a rabbit, another dog, or anything else off it, whatever you do will not make it release, a bucket of water is usually effective.
