I agree - if you accidentally get on the business end of a dogfight it can happen. When I had a Pyr I read that the suggested way of separating two fighting Pyrs was to grab their tails to pull them apart (Pyrs don't mind you grabbing their tail for some reason) but never get in front. What I've also read is that if they accidentally get you they immediately shrink back and act chagrined - biting the alpha is a no no and in any case most dogs have been bred for bite inhibition towards humans. But I KNOW how scary it is to see any sort of dogfight or serious prey drive.

And I hope you're all OK now too!!
