I need some games and activities that will help stimulate Cody's brain as well as excersize him. He needs some things we can do at home, on walks and anything else that will help him stop cheweing stuff when he gets bored. We want to do tons of stuff with him because he needs that stuff, when we have long soccer sessions he doesn't act up but other times he does when we dont do stuff. So we need some new activites or tricks or anything. Please HELP
