Anybody here pick up dog poop as an added service for their mowing clients? What or how do you charge? Per dog - size of dog etc. ? I have seen a few people in my area run ads just for poop pick up? I can't see how its profitable as a single service. I have 3 dogs in a relatively small yard and I occasionally miss a few spots especially in my long 4'+ Kentucky blue grass. Grass doesn't grow back instantly but dogs are a different story. Any input appreciated.
