Exercise

Ok, I admit it.
Boone uses the treadmill more than anyone else.
He does run on it several times a week, especially when it's very hot outside. We trained him when he was a puppy and he will run for about a quarter of a mile at a fast speed, jump off, run through the house and jump back on the treadmill to repeat the routine a few times.
He also takes naps on it. :)
