Ok, so the roomie had a German Shepard that stayed inside. The carpet was GROSS!! She vacuumed and rented a cleaner and cleaned it. It looks a little better but it stinks way worse. I guess getting it wet really stunk it up. She was always vacuuming with all these powders and sprays to get rid of dog odor, well it stinks. It's been about 4 days since she rented the cleaner. What can I put on it to help with the stink? She had all this stuff she put down but it just covers the smell, I want it gone. Anything?
