1. Dog poop is NOT good fertilizer. It's toxic to your lawn! The high nutrient concentration in dog poop will burn and discolor the grass, creating "hot spots".
2. Pet waste is teaming with E. Coli and other harmful bacteria including fecal coliform bacteria, which causes serious kidney disorders, intestinal illness, cramps and diarrhea in humans. (There are 23 million fecal coliform bacteria in a single gram of pet waste).
3. Some of the possible ways a dog or cat can obtain various different parasites, viruses and stages of bacteria from their own poop include: rolling in their feces, pawing at it, and in rare instances even eating it-coprophagy. Some ailments that can affect humans are: Parvo Virus, Trichinosis, Whipworms, Hookworms, Roundworms, Giardia and Coccidia.
