The loose skin that has been selectively bred into fighting dog breeds (most 
notably the Shar Pei) 
isn't a form of predator avoidance - in fact it's the opposite. It allows a dog 
that has been grasped 
by the throat region to turn around and counter-attack its opponent.

I'm fairly sure that such loose skin hasn't appeared in any wild canid species 
though, and is mainly 
a product of deliberate human breeding.
