dead patches of grass
Hi, April. Get powdered gypsum from your local garden center. It's very inexpensive, and gypsum can help the excess salts from the urine flush down through the soil profile when it rains or the sprinkler runs. Even with gypsum and re-seeding the spots, I doubt you'll get grass to survive there if doggy constantly urinates in the area, but it's possible some of the lesser-used spots will recover.
