General Lee loves to play with the laser.

He will sit at the dresser until I get the laser and then he will chase it and bark like crazy. If I turn it off, he will hunt for it for a bit. It is great exercise especially when I run him up and down the stairs. His little tongue will be hanging out of the side of his mouth and he won't quit. I have played with him for over 15 minutes non stop and he does not wear out. The problem is that he always has to stop and poop. Sometimes he just stops and pees also and not on his pad.
Any ideas on how to control this? When he stops and pees, we stop playing, but I am not sure if that is the right thing to do either. The weather here is pretty harsh and we can not go out for more than a potty break. He will do this even when I have taken him out.
