Of all the jobs I've had to do as a mother, that is the one that grossed me out the most. Some #%@#% would let their dog roam and use our lawn to do its duty and one of us would invariably step in it. And we don't even own a dog. It would always happen to a pair of sneakers that we couldn't afford to just throw out; like new ones with LOTS of tread. ARGH!
We're dealing with the neighbor's dog too. She thinks our lawn is her territory and even barks at us once in a while when we're on it. :). I used to have to clean out our rabbit pens. Those rabbits must have had chronic diarrhea or have had pooping genes because they could fill up a cage faster than anything. I absolutely hated that job and can hardly stand to be around animal doo-doo any more. My wife usually cleans the litterbox since I can't stand it (she got the cats anyways:0).
