Dog urine can create small brown lawn spots surrounded by darker green grass. The concentrated salts and nitrogen in urine can injure turf where a dog repeatedly urinates in the same place.
What to Do With a Fresh Urine Spot
If you see the dog urinate on the lawn, thoroughly watering that spot soon afterward can dilute the urine in the soil. University of Minnesota Extension notes that thoroughly watering dog spots followed by reseeding usually allows new grass to fill the dead area.
How to Repair Existing Brown Spots
- Rake out loose dead grass.
- Water the soil thoroughly.
- Loosen the surface lightly if needed for seed-to-soil contact.
- Reseed with a grass appropriate for your lawn and climate.
- Keep the new seed consistently moist during germination.
How to Prevent Repeat Damage
The most reliable prevention is behavioral: train the dog to use a designated area or rotate where it urinates. Watering high-use spots can reduce concentration. There is no need to add “soil cleansing” chemicals or supplements to the lawn.
Do Supplements Change a Dog’s Urine?
Do not give a dog dietary supplements or products intended to change urine chemistry solely to protect the lawn unless a veterinarian recommends them for the dog’s health.
Bottom Line
Dilute fresh spots with water, reseed dead patches, and reduce repeated urination in the same location. The lawn usually recovers when the damaged turf is repaired and the source of concentrated urine is managed.
