Clean the carpet with an enzyme cleaner like Nature's Miracle. Follow the directions and it really works. If a dog can smell even the slightest bit of protein from the urine, it will return to the spot. Cleaners with enzymes contain special bacteria that actually "eat" the protein, so there is NO trace of scent left. These are different than cleaners that neutralize the smell. You can even buy a black light that will show you all the urine spots, and just spray those. Give the product time to work. |
