I was skeptical at first but figured I would give it a try. I have three dogs and one who is older. This product did exactly what it said it would do. Old odors I had in bedroom are gone. I could not believe it! Now when my older pup had an accident I simple clean the area and spray this over the area. I no longer have those lingering odor issues. A long as they make it I still have this product on hand. I originally bought the two 32 oz bottles and will be ordering more once I open bottle #2.
