Loose hair, dead skin and dander are attracted to the rubber surface of the KONG ZoomGroom like a magnet, then they lift away cleanly and easily! One-piece, flexible rubber design is comfortable to hold in either right or left hand. 3/4" rubber teeth reach through the coat, down to the skin to massage and stimulate circulation. Also great to use when bathing your dog, it really helps to work up a rich lather to get your dog's coat clean down to the skin.
