I know it's not hogs, but this is too similar not to put here... This is, from what I can tell, a Caucasian Ovtcharka(Russian sheep dog) and a Wolf hound, back when they were bred to work.
I know it says "Wolfhound vs. two wolves" but there's definitely an Ovtcharka there too. Beautiful to see a dog do what it's bred to do. That Wolfhound is a bad dude... Wonder if any of that working blood is still out there?
