My dog is 1 years old and still loves to play, I try to get in a good solid hour of fetch or play toys anything to get her to use some pent up energy... Its cold here and normally we play ball outside. I get on the floor play toys with her, throw the ball etc... I even got her a weazel ball, 20 minutes playing with that she is exhausted. They have them on ebay for a few bucks.. When you are eating or cooking, try giving him a bully stick or a kong to keep him busy, chewing really tires them out too!
