Just a quick hope-I'm-being-silly question! I have a dog, and when he gets back from walks we towel him dry. It sets my OCD off a bit as DH happily towels his feet then his back. This makes me worry that if he's stepped in cat poop (cats poop with upsetting regularity in our yard) it'll get spread onto his back from the towel and therefore when I pet him or he sleeps at the foot of our bed I'll get it on me. Does anyone else with a dog worry about such things or is it just silly?
