Not your average thread here but I'll give it a shot.... A Landscape Designer friend of mine got a call to bid an install in a side yard that's been a dog run for years and years. Its bad. Besides being totally gross she wondered if there'd be a greater likelihood of unfriendly beasties in the soil as a result of pet wastes. I couldn't say other than I know most composters recommend not adding pet wastes to the pile. Any thoughts about how to approach a situation like this?
