Help, our dog is destroying our grass!

[The Mystery Machine]

As I said, my male dogs don't kill the grass from peeing on it (reading the other posts, we do have great drainage so maybe that is why)
BUT, our younger dog has made a huge mess from playing!!

My male dog pees straight acid, I swear. I have asked the vet and he says some dogs have stronger urine.

I have Dobermans too! Aren't they awesome! I teach my dogs to go in the far backend of my property. They're good about this 90% of the time.
