Why does dog pee kill grass?

Dog pee can kill, or discolor, grass because of the chemical compounds found in your dog’s pee. Any of the nutrients that your dog eats in their food and supplements that aren’t absorbed in their bloodstream get filtered out through their kidneys and end up in their pee.

So as your dog pees in the grass, and the water is evaporated by the sun, high concentrations of nitrogen are left behind. Even though nitrogen is often used in lawn fertilizers, too much nitrogen can hurt your grass.
