I was despairing about what to do until I discovered The Petlab Stain & Urine Remover. Have just got to work on a patch of carpet our adorable but incorrigable rescue hound turned into her preferred toilet spot even after just being outside. The urine smell which permeated the air has been replaced with a very nice and not overbearing fragrance. Just day one but already she seems to have reaised this is no longer her personal patch. That didn't stop her finding carpet in a wardrobe so Petlab to the rescue again. Thank you for creating these products and for giving us pet lovers our sweet smelling lives back again.
