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. Comes in pink and blue - if you have a preference on which colour you receive then please specify this at checkout.
