This twin pack comes with one chicken-flavored and one original-flavored FlexiChew Bone. Nylabone FlexiChew chew toys are made from softer material for moderate chewers. The FlexiChew Bone keeps dogs entertained, and the bristles raised during chewing promote clean teeth and help control plaque and tartar buildup. Not recommended for strong chewers. (Different dogs have different chewing styles and strengths, even within the same breed, so be sure to choose the correct chew size and type for your dog.) br/>Sold in Quantity of: 1
