Lol this thread is too funny. I had a customer whose yard was unreal. Said the kids were suppose to pick up the poo before we got there. Rarely it happened. Had to use 21" baggers in the back yard. Yes, there was a poo charge. If I recall correctly they had a golden retriever. Not the smallest piles.
And now my own yard is the worst one of them all. Have two dogs / horses. Big one is half lab half mastiff (130 pounds) and the smaller one is half lab half rot (100 pounds). As my father so eloquently put it, "He don't poop, he shits!"
