If you own pets, then you’re probably aware that their waste can be hard on your landscaping. Dead grass and brown spots can be a common and unwelcome result when your lawn doubles as a pet potty.
At first you may notice some spots on your lawn looking especially green as the nitrogen acts as a fertilizer for your grass, but as it accumulates you’ll start to notice the dog waste is actually killing it. This “urine burn” effect is from the nitrogen found in your pet’s waste. “Most of the effects are from either concentrated urine or feces, with a high concentration of wastes overloading the lawn,” says Dr. Steve Thompson, clinical associate professor at Purdue University’s College of Veterinary Medicine and director of the Pet Wellness Clinic.
