Check out ‘TreT’, an American Stafordshire Terrier (aka PitBull) that busts out with Parkour (aka freestyle walking):

Hehehe…TreT is friggin nuts. Leave it to the Ukraine to get their dogs involved in an already crazy sport. This is the first I’ve seen or heard of a dog doing parkour. Good luck running away from this dog if it starts chasing you…hehehe.
