3 Reasons Your Dog's Urine Kills Your Grass — And What to Do About It

One of the most common questions vets answer is, 'Why does my dog's urine kill my grass?' This problem must be addressed on 2 fronts - what to do for your dog, and what to do for your lawn. Advice for both, inside.

STORY AT-A-GLANCE

  • Most veterinarians at one time or another get questions from clients about why their dog’s urine burns the grass … and what they can do about it
  • There are three reasons a dog’s urine burns grass: an alkaline pH, concentrated (vs. dilute) urine, and nitrogen load. The most important factor of the three is urine pH
  • Dogs are carnivores, and as such, their urine pH should be on the acidic side – ideally from 6 to 6.5, but no more than 7. A urine pH over 7 will not only burn your grass, it can predispose your pet to struvite crystals and other urinary tract disorders
  • A dog’s urine pH can often be maintained in the healthy range by feeding a species-appropriate diet — low-carb, grain-free, potato-free, and preferably fresh or at least canned food for the increased moisture content
  • If improving your dog’s urine pH doesn’t fully resolve the problem of your burned lawn, alternatives are to water down the spots where he urinates, or cover the area with about an inch of compost to help rebalance the soil pH
