Taking advantage of the great weather today, we took my dog Chance out in the back yard and threw his ball for him. He gets taken on walks/runs daily, but this is like a drug for him. I swear that he would do this until he died of exhaustion. It's hard to stop him though, he has so much fun that once you are holding the ball, he can't keep still, he dances in place as he tries to control himself. You can throw any other distraction at that dog and so long as the ball is in play, he won't be bothered for anything else.
