If a dog poops in our yard and the owner picks it up, that's a neighbor I'm glad to have in our neighborhood. Life's too short and there are far too many other reasons for my grass to not grow than any residual dog poop left in my yard.
Cow manure (Black Cow) and Milorganite (microbes that have digested wastewater in Milwaukee) are two of the best fertilizers for many of our lawns...
Heck, that grass with the residual dog poop that the owner left after picking up the mess may be the greenest grass in your lawn
