Dog poop is not a good fertilizer. Leaving it on the ground or concentrating it one specific area of the lawn can harm soil quality.

The idea that dog poop is a natural, organic fertilizer is a common misconception from the use of cow or horse manure as a soil enhancer. In order for animal waste to be used as an effective fertilizer it must consist mainly of digested plant matter.

Cows and horses are herbivores, which makes their waste ideal for use as fertilizer. In contrast, a dog’s diet is made up of mostly animal products, making their waste unsuitable for soil enrichment.
