My male shepherd is a funny dog and probably pretty smart. He starts getting really excited when I was getting the runt dressed up to go play outside. As soon as I open the door for the kid he runs out like a rocket and starts spinning in a circle on the deck. As soon as the runt steps out he stops, sits and waits. Tail going 100 mph. He likes catching snowballs and the runt likes throwing them.

By the time they are done both of them should be good and tired.
