I could sit and watch the puppies play all day. They are just starting to bark and yelp and wag thier tails. They have a hard time getting traction on the wood floor but they were getting the hang of it by the time we left. I can't wait to see them again, I am sure they will be experts at it by then. I don't know how we will ever pick one! We are still leaning towards the one with the all black face.
