The dog and I have a game we play when I'm shoveling snow. He accompanies me while I scrape a path clean and get a good shovel-full of snow. Once my shovel is loaded, he gets into position. And then I fling that shovel-full of snow into the air as far as I can, and he twists himself into a pretzel trying to eat it as it falls.
It's actually pretty cute. He's jumping and twisting like a Chinese acrobat, jaws working so fast you can hear his teeth clicking together like an old-fashioned typewriter. And I'm just shoveling snow. Gives him a good workout in the morning.
