To add to the list:
Fetch
"Find it" (Hide and seek with a toy) - this is hilarious to watch and a great way to burn off energy. I will grab his fetch toy (once I've gotten tired of fetch), go into another room, pretend to throw it - he chases where he thinks it went and I then turn the corner and toss it in a different direction. When he comes back to me confused because he can not find it, I say - go find your toy - go look! And he takes off running through the house in search of it. And....he is just soooooo proud of himself when he does locate it
