One of my dogs will attack her back foot sometimes. It is like she doesn't realize that it belongs to her. She has never broken skin or anything. It is funny to watch, but I soon as I see her do it, I distract her so she will quit.
You should send this video to Animals Planet Funniet Videos, you might win, who knows. Some time they have some silly stuff on TV it's not even funny, but your's took the cake, that is tooooo funny!!!!!!!! lol
I counted 13 times that dog snapped his/her jaws in aggression towrds the foot or the bone. It reminds me as how fast a dog bite can happen. The video is funny, but it is also an example of how fast a dog really is, if they have the intention to bite.
