We all love our dogs, and all dogs are descended from wolves. It’s hard to believe while they are in a ball on the couch, but it is true. This video focuses on the wolves of Yellowstone. This footage caught some never before seen behavior of wolves. There were no couches harmed in the filming of this video, but I can’t say the same for the bison. If you haven’t seen this month’s National Geographic, it is completely dedicated to Yellowstone.
