Ewwww. Gross! What's that with your car keys? It's a surefire way to make sure nobody walks off with your keys by mistake, that's what! While the Doggie Doo key chain is not visually appealing at first, you might say it's a "diamond" in the ruff. This disturbingly realistic pile of dog poop is also a great gift for someone who's a little um, piece of crap. The novelty dog poop key chain is one of our best sellers!
