Dog waste is an environmental pollutant. In 1991, it was labeled a non-point source pollutant by the Environmental Protection Agency (EPA), placing it in the same category as herbicides and insecticides; oil, grease and toxic chemicals; and acid drainage from abandoned mines.
Dog Pooh Is Far from Good Fertilizer
Dog waste does not make a good fertilizer. It is actually toxic to your lawn, causing burns and unsightly discoloring. Beyond your grass, it has been estimated that a single gram of dog waste can contain 23 million fecal coliform bacteria, which are known to cause cramps, diarrhea, intestinal illness, and serious kidney disorders in humans. EPA even estimates that two or three days’ worth of droppings from a population of about 100 dogs would contribute enough bacteria to temporarily close a bay, and all watershed areas within 20 miles of it, to swimming and shell fishing.
