You could also play hide and seek with yourself and with items he likes. When it's all rainy and nasty outside I like to play hide and seek with my dog. I wait until I can sneak out of the room (very difficult) and go and hide and just wait for her to find me. Then it all happiness and play time. You can also introduce clicker training for tricks and obedience. You can also play the games like which hand is the treat in, find the hidden toy (you can use a kong with something tasty in it), You can practice the place command. Shake hands and high five is easy to teach, as well as touch my hand with your nose. Use your imagination and imagine you are stuck inside during a hurricane and need to keep your dog occupied. Actually that is the reason I used some of these - we have a lot of hurricanes go by. Good luck on your recovery and keeping the furry ones occupied.
