The JW® GripSoft® Undercoat Rake has a row of round tipped teeth that are designed to loosen lightly matted parts of the coat and to lift out dead and shedding hair from the undercoat. The GripSoft non-slip ergonomically designed handle is more comfortable on the hand making grooming precise and a more pleasurable experience for you. Short Teeth are most effective on medium to large sized breeds with short-haired coats while regular teeth are most effective on medium to large sized breeds with medium to long haired coats.
