How to Get Rid of Dog Urine Smell. You love your dog, but inevitably they may have an accident in the house every now and again. Dried urine has a strong ammonia smell that can be difficult to get rid of. By treating fresh urine promptly, removing old odors and preventing accidents in the first place, you can eliminate dog odors and make your home smell fresh again. Blot the urine right away. If you see your dog pee in the house or find a wet urine stain, blot the spot with a clean towel immediately. This will soak up as much urine as possible, diminishing the possibility of the pee soaking into your rug or upholstery. Use water and a few drops of soap to dilute the damp spot. Get a bowl of warm water, and put a few drops of mild soap in it. Use a clean towel to wipe the wet spot with the soapy water, blotting with a dry towel. You can do this a few times until no traces of the original dog stain remain. Sprinkle the spot with baking soda.
