We're getting ready to move and when our dog was a puppy, she was very stubborn about being potty trained. We would clean up after her, but there is a smell that just won't go away. We now have to get the urine smell out of the carpets to get our deposit back – we've used a Rug Doctor but that only helped with any stains that might have been there, such as drink spills, etc. and didn't really help with the smell. I need something that will work on the smell, whether it's a home remedy or something you can buy at the store. I've tried a couple of products and they don't seem to do the job. HELP!!! I'm desperate…I will even have the carpets professionally cleaned if I need to, but wanted to see if anyone had any good ideas first.
