Question: Is dog poop bad for grass?

Answer: Ranjiv,
Yes. Not only is it smelly and unsightly, but it poses certain health risks. In small amounts, dog (and cat) feces will produce a fertilizer effect on the lawn that results in dark green patches and areas of noticeably taller grass. In large amounts or when left on the lawn for too long, dog feces will release excessive amounts of nitrogen and salts into the soil as it breaks down, which results in brown patches or "burn" marks on the lawn. Over time, areas suffering only mild damage will recover on their own. Dark green patches and areas of tall grass are likely to remain for a few weeks. In areas of sever damage, however, the grass may need to be completely reseeded or patched with fresh sod. Animal waste is full of nitrogen. Think of animal urine like a concentrated liquid fertilizer and feces as a slow release fertilizer. Like any fertilizer, both will burn your lawn when used in excess.
Even more important are the health risks. Dog feces attracts breeding flies, which transmit disease. Feces can also be a vector for transmitting certain diseases between dogs and people (Salmonella, Campylobacter, Roundworms and Hookworms). This is especially true of children, which are much less likely to wash their hands after playing in the yard. The eggs of roundworms, for example, are passed in the feces of dogs and can survive in the soil for many years-regardless of disinfectants or weather extremes. If the eggs are accidentally ingested, the worms can cause serious neurological, pulmonary and vision problems in the body. This is why many municipalities require owners to clean up after their dogs in public parks and why you should never add animal waste to your compost.
