Product Introduction An edge guard has been added to prevent the teeth from digging into the skin, and special stainless steel teeth gently remove the undercoat without damaging the topcoat or skin. Supervised by a veterinarian, it appeals to health benefits and is effective for hairball (trichobezoar) prevention, heatstroke prevention, and skincare. The easy-to-grip handle is ergonomically designed to gently remove the undercoat. How to Use 1. Untangle any mats or tangles before using the FURminator. 2. Brush along the direction of the hair growth. 3. Press the one-push button to remove the hair from the teeth. Cautions Do not press hard against the pet's skin or pull forcefully, as this may cause inflammation. Do not use on pets without an undercoat, pets with skin inflammation, pets with sensitive skin due to allergies, or pets with a tendency to bite.
