@srdceleva As I previously mentioned I’ve seen videos of a couple of guard dogs taking on a wolf pack and making short work of the wolves they managed to catch. In seconds. The wolves just ran. Dog breeds are more specialized than wolves and as impressive as wolves are overall I wouldn’t expect one to fight a pit for example and win. I wouldn’t expect a sheep-dog to fight a pit and win either. What I would expect is a sheep dog to be able to protect a herd from wolves and other predators without having to keep more dogs than there are wolves out there. This makes no economical sense.
