Cleaning dog poop from your back yard is not a fun chore. It is necessary for few factors: 1 is for sanitation.   Dog poop draws flies that raise their families in the dog muck.

 2 is the smell.  Dog poop stinks, ruining the general ambiance of backyard barbecue.  Backyard looks like toilet in just few days of not cleaning. 

By the County code you must clean it within 24 hours.  Clean it, would you.
