How to Stop Pet Urine From Burning a Lawn

Updated April 17, 2017

Dog urine is highly acidic, and the acid is harmful to grass when the dog waters the grass with his waste products. There is no ingredient in dog urine that is necessarily toxic to grass, but the disruption of acid levels causes grass to "burn." Brown spots of dead grass will appear wherever your dog (or a neighbour's), relieves himself frequently. Preventing your lawn from burning from pet urine requires diligence.

Determine the culprit behind the pet urine. If you have a yard with a fence, then you know that your dog is the sole reason your lawn is burning. Adjusting the animal's diet can fix the problem easily. If other animals may be poisoning the lawn as well, your strategy is different.

Add 1/4-cup of tomato juice to your dog's food, according to a traditional home remedy. This will level out the acidity of his urine. Chances are he will welcome the taste. The results won't be apparent right away.

Water the section of your lawn where the pet urine is most prevalent. Water dilutes the urine, balancing out its acid levels. It also makes other animals less likely to detect the urine and add some of their own.

Use a low-nitrogen fertiliser on your lawn to decrease natural nitrogen levels. You can control your own dog's actions, but it can be difficult to control other people's pets. By fertilising with low-nitrogen fertiliser, the urine's acids will only succeed in bringing your lawn's pH levels to normal. The grass won't die because the acid levels stay in check.


Train your pet to urinate in one particular area for easier management.


Choose fertilisers that are pet-friendly as well as low-nitrogen. Use low-sodium tomato juice, if you add it to dog food. Consult a veterinarian before changing your dog's diet.
