Watch This Dog Get Scared by a Leaf

They say that dogs can hear at a different pitch than humans. Since none of us has been a dog before, maybe they can see things we can't, too. I have no proof, of course, but this is the Internet, which doesn't require proof (or facts, for that matter). I have Internet-worthy proof (i.e. none) that this dog is bravely attacking a spirit from another realm that's trying to possess the inhabitants of his home.
