HI, I am wondering if anyone has any suggestions for a backyard. My dogs use our backyard to play, romp and well..... to take care of business. Here is my questions. Is there a way to make the grass not be turned brown from where they pee? I have a green lawn with spots of dried up grass. I love my dogs, they are more important than the lawn. But I was wondering if there is something I can do for it to help it along?
