So you've seen my comic strip (below) BUT I ALSO have an idea for a million dollar invention. It's a plastic bagish thing, with tread on it, that you put over your shoes when you go to the dog park, so you don't get poo on your shoes.
Lord knows, no matter how careful I am, I always get poo on my shoes at the dog park. And sure you can clean it off, but they never really smell the same again. I'll call it the "Poo Shoo".
