FURminator / Large Dog, Long Hair Promotes health benefits under the supervision of a veterinarian. Recommended for hairball, skincare, and heatstroke prevention. The edge guard prevents the teeth from digging into the pet's skin, making it gentle on the pet's skin. Special stainless steel teeth gently remove the undercoat without damaging the topcoat or skin. The gently curved teeth fit the pet's body better. You can easily remove hair from the teeth with a single push. This is a new, unused item.
