I have long hair Dachshunds and also care for a couple of visiting long hair Dachshunds. Needless to say, they love to romp and play both indoors and out. The only problem… I still have carpet in one of my rooms and so their “odors” get stuck in the carpet. I vac daily and steam clean every six months, but the odor comes back in a short amount of time. I used this odor eliminator when it arrived and was pleasantly pleased with how well it worked… both instantly and hours later. My home smells fresh again and no longer has that “wet dog” odor.
