Tennis balls, laser pointer, tug ropes, and walks. Also, mind games, like asking him to find things, or playing hide/seek, help wear him out. Mine has his bursts of energy but will happily cuddle near my feet or on the couch with me. He can't be left alone and have the run of the house or yard, though. He used to shred the blinds, so I crate trained him when he was a pup. He actually prefers it as his safe space/den if things get too chaotic or when I have to leave him home.
