Answer: Aside from fencing your yard to provide a dog run, there's not much else you can do to prevent the burned spots in your lawn. Diluting the urine with water does help, but I don't know that having the sprinklers come on every 5 hours is actually doing any good. Unless you dog is trained to go a few minutes before the sprinkler comes on, the water may or may not turn on soon enough to dilute the urine before it soaks into the soil.
Wish I had more suggestions!
