To get rid of yellow burn spots in your lawn caused by dog urine: Dissolve 1cup baking soda into 1 gallon of water in a watering can. Saturate the spots every 3 days. The baking soda not only neutralizes the acid in the soil to allow grass to green again, it deodorizes the area. This stops the dog from recognizing the spot. If this can stop a dog from recognizing the spot, I would be amazed!
