FYI Dog owners:
Although you can't do it to a dog that is attacking you, because they are way too fast and you'll never get ahold of them, a dog that is already biting something (your dog) can be choked unconcious very quickly.
What you want to use is the rear naked choke:
Just remember that a dog can spin its head 180 degrees and bite so you want to keep your chest firmly against the bag of its head so it doesn't let go of your dog and turn on you. Just keep choking it with steady pressure. Don't burn out your arm strength all at once by going as hard as you can. Just nice steady pressure.
I've broken up several dog fights like this. It's fast, effective and relatively safe for all parties.
