Gently cleans your pup’s paws before they track mud and dirt across floors, rugs or upholstery. Just fill with warm water and plunge paws into the top, one-at-a-time. The water and soft, deep cleaning bristles do the work! Dry each paw with a towel, and your dog can have the run of the house or be ready to travel in the car mud-free. No mudroom should be without it! Two sizes: Small for dogs 15-20 lbs. Large for dogs 20 to 120 lbs.
