 I've had some where the urine would burn out the lawn, and I've had some where it had no effect at all. Is that the type of grass? Is that something, I'm kind of going off page here, would that be something with the breed of dog or their diet? And you might not have any clue on that part, but I was kind of leaning more towards would it be the type of grass, where sometimes it affects it and sometimes it doesn't.
