This is a miracle tool for paw-parents of breeds with sufficient undercoat! The Coat King has uniquely ground teeth which makes the removal of dead hair, undercoat and knots quick and easy. To use, apply to a dry coat and with light pressure, comb out in the direction of hair growth. As you do this, the straight hair passes through the teeth and the fluffy undercoat is removed. Not only does it remove the thick undercoat giving much relief to your dog, it creates a light outer coat and seriously decreases the amount of hair loss deposited around your home. Thank me later x
