Lawn burns from pet urine can be unsightly and cause damage to your grass. According to the Doctors Foster and Smith website, large female dogs cause the worst urine burns because they deposit a large quantity of urine in one spot, as female dogs don't spray urine around the yard like male dogs. There are ways to treat grass burns, both through active prevention and treatment to heal those yellowish dead spots scattered around your yard.
Walk your dog a couple of times a day to decrease the number of times your dog urinates in your yard, or train your dog to urinate in a designated area that you can cover with mulch or pebbles instead of grass.
Add water to your pet's food to dilute the nitrogen in its urine, which will help prevent lawn burns.
Add unsalted broth to your dog's water, which will make it more thirsty and increase its water consumption.
Feed your dog higher quality dog food that it can digest more easily, thus breaking down more nitrogen.
Give your dog supplements sold in many pet stores that are designed to help decrease the nitrogen levels in your pet's urine and prevent grass burns.
Water the areas where your dog has urinated to dilute the nitrogen levels in the grass and prevent grass burns. You can water the area up to nine hours after your dog does its business, and you want to rinse the area with about three times as much water as your dog urinated.
Reseed the burnt area or dig up the dead grass and replace it with a new piece of sod.
Replant the grass in your yard with a variety of grass that is more resistant to lawn burns. Kentucky Bluegrass and Bermuda are very sensitive to urine, but ryegrasses and fescues are hardier.
Stop using fertilisers that are heavy in nitrogen. Grass likes nitrogen, but the levels in your dog's urine are already so high, it overloads and kills the grass.
