This is amazing stuff! We have an old and a young dog.! Both have had urine, poop and throw up accidents. Poop accidents are especially nasty. My Per Peed removed all of the stains and odor ( sometimes with more than one application). Even worked on old stains that had been around awhile. So easy to use! I know some friends who have new 4–legged family members. I highly recommend My Pet Peed!
