My dog is insanely hyper. Although, he's pretty lazy during the day. He's only REALLY excited when my dad gets home from work. It's really funny, when you say, "Do you want to play ball??" my dog starts freaking out and whimpering at the door. His favorite game is chasing a basketball (which is just half as big as him) up and down our backyard as we through it back and forth. That's all. He just likes chasing it.
