I was watching a dog show the other day with the boyfriend and we saw the cutest thing: a pug walking on it's own little pug-sized treadmill! The owner apparently used it as part of the show-dog's conditioning routine and had a fan set up in front of it to keep him from getting overheated, etc.

Apparently this is very common, the boyfriend informed me, as the Vendor area at the larger shows would often feature all sorts and sizes of pet treadmills. But the little pug seemed quite content trotting right along!
