Can anyone help me rescue my grass?

Just wondered if anyone had any remedies as to how I can stop the dogs from killing my lawn with their urine. The garden is full of brown patches and it looks awful - had a look on the internet and the main thing seems to be to water the urine as soon as they have done it, this isn't always possible as I can't see where they go on a night time without following them all over - plus if you do follow them, they won't go to the toilet and think it's fuss time! Another suggestion was to put tomatoe ketchup in their food (looked this up and apparently it dehydrates them due to the large salt content, making them drink more water and diluting the nitrogen in their urine - don't like the sound of this one). So has anyone tried anything? I wouldn't be so bothered it's just that we live in a rented property and the garden looks such a state it's embarassing! Thank you in advance

Soon as they wee on it hose it down or pour a watering can over it, it will stop the brown patches

I can't always do this - like I say on a night I don't see where they wee as I don't go outside with them (they just think I'm there to play if I do so I have to leave them alone)

Can you not watch from a window and go out after them or teach them to wee on the path or patio only

Apparently tomato juice to garlic to salt to vitamin C in your dogs diet helps with this :S so i read lol.

You could train them to go to a certain area. Seen it quite a few times, they learn that that is where they must go, like fence a little area, take them to that area for a the first few times, when they need to go, and lots prase when they do. that way you only have to worry about watering and looking after that area. its a good way to stop spoiling of lawns etc.
