Give your dog or cat a spa treatment with this grooming brush. The bristles are fine  stainless steel bent in 140 degrees that are meant to penetrate deep into the coat and groom the undercoat effectively without irritating your pet's skin! After brushing your pet, simply push the button and the bristles retract back into the brush, making it super easy to remove all the hair from the brush so it's ready for the next time usage.
