It is ridiculous they bought it.

"Hey mommy, I want a dog that shit for Christmas!!!"
"Oh baby, so you want 'Doggy Doo'?"
"Oh yes mommy, I can't wait to see that doggy yellow shit come out the back door!!!"

Go to a damn dog park!!! You can see dogs shit all day. Hey you might even get a chance to pick some up!!! Just like the game, but for free!!!
