We have recently had a litter of puppies and we kept two girls. Toilet training hasn't been a lot of fun having two to keep an eye on. I have a pet shampooer and have been using britex shampoo. No matter how thoroughly I cleaned it I could always smell a slight or not so slight urine smell. We have used deodorisers, smelly candles etc. We bought the En.Zyme solution and the eco carpet shampoo. So, the smell didn't jump out at me making me think is this strong enough to work. Well, surprise surprise after using it couldn't smell any urine smell at all. The carpet looks brighter and cleaner. But that's not all... the girls are now whining to go outside to go to the toilet. Is their a deterant in this product as it certainly seems like it ? Thank you for saving my carpet and sanity !!!!!
