content: I've heard of this one but I've never heard a first hand account of someone doing it successfully, so it may be a bit of a tale, I don't know. I would assume it would be difficult to do given the scenario, people getting in the way etc.  Something else you can do, though, is to lift them up by their rear end. Their source of power (and this goes for any dog) is their hind legs and them being planted and pulling with all their might. With their legs in the air they lose that. The dog may turn on you though, so be careful of that. What I would do is one arm under the hind legs and one hand on the collar or scruff of the neck. Don't just lift them up into the air by their feet as that will almost certainly get the dog redirecting onto you. If you see one attacking a child, or one attacks your own child, or even your dog, put it in a headlock and choke it out just as you would with a human. Don't kick them, hit them, or pull on them...these things will likely do nothing. Take the aforementioned advice depending on how serious the attack is and you will stop the dog.
