The KONG Puppy Teething Stick™ is made with unique KONG Classic puppy rubber. The Denta-Ridges™ gently clean teeth and soothe sore gums when chewed. Fill them with Easy Treat™ or Peanut Butter to encourage long-lasting play sessions. Playing with the Puppy Teething Stick™ helps teach puppies appropriate chewing behavior. Use with puppies until they reach 9 months, then they can graduate to KONG Classic Rubber toys. Available in pink and blue.
