I love it Fred! I don't watch the show too much ('cause it reminds me too much of work, LOL), but that reminds me of how Cesar Milan the Dog Whisperer exercises some of his dogs he works with, but he wears some really funky looking skates. If I lived in a place that had smoother pavement, I would so do this with my dogs.
My dogs are definitely on their summer break. Just doesn't seem like I have time to let them run when the temps are a bit cooler out. However, it is only in the mid70's this evening so I was thinking about heading out the door to do chores and let the beagles do their thing while I do mine. It's probably been 5 or 6 days since I've let them run a rabbit. Sounds like a plan.
