You all know about Chim's incredible endurance. He can walk as far as you want to take him, and still have gas left in the tank for more. It's too bad Linda can't run with him. I think that is the only thing that would truly tire him out when he got back home. This is a terrible video, but Chim moves so fast Linda could not keep the camera on him. Each time she threw the ball to him, this is the way he ran before he bought it back to her. It was so funny, Linda finally decided to go get the iPhone and video his laps. At the end of each lap he would stop to cough, then bring the ball back to her. When Sarah gets home, Linda is going to ask her to help her put some music in the background like she does for her videos.
