1. Fill the big food cup with dry dog food.
2. Step out the back door onto the deck.
3. Shake the cup.
The dog will appear out of nowhere and to do her happy dance: twirl to the left, twirl to the right, take a flying leap off the deck, and keep twirling until the food gets dumped into the dish. The dog doesn't bark much or growl or whine or fuss, but I'll tell you one thing: the dog can dance.
