Hi Vicky, I too have a similar problem with a male dog (10 months), he has left brown patches on my lawn (has not learnt to raise his leg), my backyard has large craters which you have to me careful not to twist your ankle in and lastly he has destroyed my watering system. My partner and i have talked about what we could do with the grass and decided that synthetic grass would be a good option and relative inexpensive. The grass i am talking about is the same as what is on tennis courts almost indestructible and if you can find a tennis court that is being resurfaced you should be able to pick it up fairly cheaply.
Hope this helps.
