I have 7 dogs ranging from 7 months to 11 years old. Needless to say with 7 dogs comes numerous accidents in the house. I tried everything there is out there to try and help with the stains/smell but nothing worked at all. I saw this and figured I would give it a try. It couldn't hurt since I have already tried everything else. To my amazement, it really did work. After that I kind of went crazy finding every stain or spot in my house and blasting them with this stuff. After a week, I ran out of product, but I am definitely purchasing more! One thing I want to say is if you spray a stain like I did and then head to work and it happens to be 80 degree weather that day, when you get home, more than likely it's going to stink. I actually sprayed a couple of spots and then went to work. I don't have central air and I just had a couple of fans running and when I opened the door to the "dog's room" boy did it stink. I cracked the window and within 15 minutes the smell was gone and the stains were gone as well. I am very happy with this product!
