I won a gallon of My Pet Peed last week and got It a few days later. When I rescued my 7 year old dog, bichon/poodle mix last year, she had a bad habit of peeing in the spare bedroom on the area rug. I tried to clean It as best I could but still left a stain. I was going to just throw the rug away when I moved. In comes My Pet Peed into my life! I read the directions and sprayed away. After a few applications, nothing. I was thinking, “what a crock!” But continued on. Then a day or two later I smelled urine, so nasty and knew It must really work. To my surprise the stain is gone. It was over a year old stain so I am in total shock! This stuff really works, even on old stains! Thank you My Pet Peed, you have a customer for life!!!
