I learned a trick from an old dog fighter (dont agree with it, but thats what he was and where the trick came from) to break a pair of dogs up that dont want to stop fighting, put a little squirt of white vinegar in the mouth and they will let go quick. Its safe and nontoxic, just dont drowned them in it. Well I used this method with a pretty nasty retic I was working with at the university. One day she just up and grabbed my thigh, I couldnt get her to let go and she was just too big to unwind so I told my colleague to grab the vinegar and we poured a bit into her mouth. You would have thought we started a campfire in her mouth or something the way she let go. I have heard of alcohol being used as well but I dont trust that rubbing alcohol has no ill effects compared to vinegar.
