This is a video of an American Staffordshire Terrier named Tret The Superdog who was trained in the art of parkour by his caretaker in the Ukraine. He is really good. Way better than I could ever do and I actually have fingers for gripping. At least I think that's what they're for. I dunno, they touch my privates!
Hit the jump and prepare to be amazed.
Thanks to Gregory and latz, who have both started training their dogs to climb walls and hang out on the ceiling.
