Video: Two dogs skateboard across Paris (most amazing thing I’ve seen in a while)

I read the title of this video and figured it was going to be somehow less than interesting than it sounded. Nope. Actually even more interesting. The dogs skateboard. They don't just stand on a skateboard while their master pushes them. The dogs flip the skateboard into the upright position, jump on, then kick start it. Then after moving ten feet and the skateboard slows down, the dog lowers one leg and gives a few kicks to get it moving faster. Absolutely amazing. I'd love to know how the owner trained them to do this.
