The JW Middleweight Chompion toy is designed for medium to large dog breeds. The durable, natural rubber material of the JW dog bone allows eager chewers and teething dogs to chomp heartily, exercising and strengthening jaw muscles. The textured bumps clean plaque off dogs' teeth, helping keep teeth healthy and clean while they play. The rubber of the toy is soft on the mouth, yet strong enough to withstand rigorous chews. The bouncy dog toy allows for hours of chewy entertainment and exercise, from fetch to tug-of-war. The JW Chompion is also available in several assorted bright colors so that pet parents can keep track of the toy with ease.
