Dog wee patches on the grass. How do I get rid?

[redrobinblue]

Didn't know whether to put here or in the Dog section - but my beloved pooch is destroying my lawn!

We've got a 4 year old greyhound rescue and the lawn is suffering - highlighted more on days like today when DC are in the paddling pool and the grass looks scorched! Anyone uses anything that works?

Thank you!

I can recommend Dog Rocks.
They are stones which you put in the water bowl and they reduce acidity in the urine which stops it killing the grass. (have a quick Google)
then just water the grass and wait for it to come back or try reseeding.
I used these and grass was noticeably better in about a week and then no sign of urine scorching afterward
lots of friends have all used them and I have only heard of one who said it was no good

We use tablets we put in their food. Can't remember what they are called though!

Following with interest, our front lawn is ruined
