pets and carpets do not mix!

[Donya Heil]

I've got a question. We have been living in our apartment for 13 mths and our lease is up in a few weeks. We paid $300 non refundable pet deposit. When we moved in one of our two dogs was just 4 months old and not potty trained at all. so he made ALOT of messes..we've tried every three months to clean the carpets..but lets just say that the carpets are disgusting. I'm not sure if we should pay for a professional to come out and deep clean them which ive gathered will cost us $170 and that may not even clean them enough..or should I just leave them for the landlord to deal with. I'm just scared they're going to not even try and go the cheap way of cleaning them and ask us to replace the carpets. By the way its a one bed room with approx 580 square feet with carpet..the rest is tile. Anyone have a clue on what i should do?
