Some dogs might even develop a favorite place to pee. Successful potty training can feel like a win for you, but when it comes to your lawn, it can feel like a losing battle. Dog pee can kill grass and leave dead spots and bald patches.
Does grass grow back after dog pee? Yes, with help. Even though brown grass is dead grass, you can reseed those brown patches and have a lush green lawn again in no time. Even if you don’t overseed, the surrounding healthy grass should eventually grow over the dead spot.
Why does dog urine kill grass? The simple answer is nitrates. When you fertilize your lawn, it already has elevated levels of nitrates, so adding a little more can harm your grass. Dog urine contains a variety of nitrogen compounds that kill grasses.
Jones says that lawn soil can be restored by neutralizing salts from the dog’s urine with products containing gypsum, such as NaturVet GrassSaver Gypsum Soil Conditioner. “To do this, get a small bag of plaster of paris, put a couple of tablespoons in the soil and gently water it in. Then cover the spot to keep the dog from peeing there.”
Feed the dog food with a lower protein content so that there is less protein and consequently less nitrogen in the urine. Many dog foods on the market actually have far more protein than the average dog needs. You can also try diluting the dog’s urine by diluting the food.
Dog poop kills grass because it’s high in nitrogen. Dogs need a high-protein diet, and the process of breaking down all that protein creates nitrogen as a byproduct. The dog then expels this nitrogen with its waste (dog urine is also high in nitrogen).
Dog poo is NOT good for weed because it’s not fertilizer like cow manure. Contrary to popular belief, not all poop is the same. Dogs have a high-protein diet that creates very acidic feces or waste products.
A natural way to fix yellow spots in the grass caused by dog urine is to dissolve a cup of baking soda in a gallon of water and pour it onto the affected area. The baking soda neutralizes the high concentration of nitrogen and deodorizes the area so the dog doesn’t recognize the spot and go back there.
