Urine Off Dog and Puppy Formula is a veterinarian-recommended product for canine urine odour and stain removal. It uses bio-enzymatic technology to permanently eliminate your dog or puppy's urine stains and odours from virtually any surface. The combination of micro-organisms and their enzymes in our non-pathogenic bacteria work together to break down the uric acid that produces urine’s pungent aroma and the urea that sticks to the surface, effectively removing all components of the urine, when used as directed. Urine Off can be used on carpet, rugs, hardwood, tile, concrete and more. Medium Size: 500 ml.
