I have no choice because the kids keep me going. If I relax for a minute Megan jumps up me that is my human two year old. So up I get and off we go. We all enjoy the park and the ball diamond were Yukon can go off leash safely. I'm not sure who gets more exercise the kids, the dog or me. Right now since it is raining, I am allowing the flying mouse [bat] to entertain Yukon. He will never catch it but he sure is trying hard.
