From what I'm told a mix of 1 part water to 1 part white vinegar is the only thing that works.

Anti-Icky Poo by Mister Max. I have had problems with my cats spraying my couch, and Nature's Miracle, soap and water, vinegar and water did nothing. Anti Icky Poo saved my couch and my sanity! Their web site is www.mistermax.com, and if you call them they can tell you where to purchase it. My problem had been going on for a while, so I soaked the couch and slipcover with it, and it took a second application in a few "popular" spots, but now (2 months later), my family room no longer smells like a toilet. I highly recommend it. Good luck!

There are many different products available on the internet that are bacteria based and the little buggers actually devour the organic stuff that causes the odor. I highly recommend this type of solution. Vinegar only masks the smell.

Our 14 yr. old dog was leaking at night. It was confined only to her bed, but whenever it stormed at night, she spread the joy around. We took care of the leaking problem and have now taken care of the stench.

this is what worked for me........or rather, for the urine smells and stains. "Spray 'n' Wash", the sort you spray on clothes to remove stains before putting them in the wash. Spray it on the spot(s), then wick off with paper towels. But make sure that the product does not contain bleach (goodbye whatever you sprayed) and does not contain ammonia (dogs are attracted to it)

Sprinkle the area with Bicarb of soda, quite liberally and leave it for a week then vacuum it up. You might have to repeat it but it really does work.

Is Bicarb of soda baking soda?

Here is another vote for Anti-Icky Poo by Mister Max. I black lighted the seldom used dining room and found had 32 "accidents" in the carpet. After retraining the cat, I used a syringe to inject the Anti-Icky Poo down into the pad as well as dowsing the top. After giving it a week to "eat" away the odor, I had the carpet cleaned.

It's expensive but truly the only thing that really works.

A good carpet cleaning mechines you will find at www.carpetcleaningla.com. Good luck!

Are you sure the smell if from the dog? I ask because there was a discussion of smelly 'new' rugs on the decorating forum.
