Our Moderate Chew FlexiChew Twin Pack is designed for moderate chewers who prefer a gentler chewing experience. The Moderate Chew FlexiChew toy keeps dogs entertained with delicious chicken flavor throughout. The bristles raised during chewing both of these bones help clean teeth and control plaque and tartar buildup. (Not recommended for strong chewers.) Go ahead and give your dog a Nylabone! For dogs up to 15lbs.
