Excellent product - I have 3 dogs & one of them is 'very' naughty with marking my carpet up when we leave her alone. The warmer, more humid my house got, the more the urine smell was driving me nuts!! I had bought the Bissell Pet Carpet Cleaner, Nature's Miracle, etc...to no avail. I finally saw this product show up in my FB ads and thought I'd try it (why not, it has a full guarantee). Much to my pleasure - it WORKED!! After finding all the 'spots' w/my UV black light and spraying them directly, the smell is GONE!! I'm one happy dog mom now!! Just ordered another bottle in case there's a future issue!!! Would totally recommend this to anyone!
