Dogs urinating on green grass often cause an unsightly problem called "lawn burn." Lawn burn occurs when a dog urinates on grass and the nitrogen present in the dog's urine burns the lawn and creates a brown area on the grass. Combat lawn burn and neutralize dog urine on grass by taking several remedial steps to save your grass. Healthy and robust lawns will withstand the effects of dog urine when you neutralize it to prevent damage.
Feed your dog a dog food that is not too high in protein. The dog's body will not utilize excessive protein, and this protein will result in high nitrogenous urine. Provide your dog with more drinking water in an effort to dilute the dog's urine.
Dilute the urine with water from the garden hose immediately after the dog urinates. Spray the water for approximately 30 seconds over the entire area.
Sprinkle a small amount of gypsum over the urine area to counteract the nitrogen in the urine. Cover the urine area with a light layer of gypsum and leave it on the area.
