Dog feces is more than just a nuisance - it can pose a serious health hazard.  Round worms and other common parasites can be transmitted via dog feces.  Infected dog droppings that are left on the ground can leave eggs can linger in the soil for years. Humans and other pets that come in contact with infected soil are at risk for infection - especially children and pregnant women. 

Dog droppings also contain bacteria and chemicals that can damage your lawn, impair the quality of surface water and cause other environmental hazards, and can develop nasty biodegrading odors.
