International Pooper Scooper Week - April 1-7

... A number of common parasites, including roundworm, are transmitted via dog feces. When infected dog droppings are left on the ground, the eggs of the roundworms and other parasites can linger in the soil for years. As a result, anyone who comes in contact with the soil also comes in contact with the infected ...
