Our Great pyr, Smokey, AKA the Great White Pasture Potato, was actually caught in action the other day. A dog, that looked to be a Rottie cross, had come into Smokey's territory. Smokey had him down and would pick him up in his mouth and shake him like a rag doll. This pretty good sized dog was a bloody mess when he was finally able to escape and run off with his tail firmly tucked, hopefully, never to return again. Good dog Smokey!
