Dog urine killing grass.......

This may be off topic for this forum, but I thought it was here where the "Pet" people visited. Does anyone have any suggestions on ways to prevent or lessen the damage of female dog urine causing those round circular burnt looking place in a bermuda grass lawn? I get asked this question all the time at work, and have experienced it first hand with my own dogs. I understand that female dog urine is worse than male urine, and that intact females are worse than spayed females.

Thanks in advance for any enlightenment.
