KONG Corkz provide long-lasting flavor and enrichment to small, medium, and large KONG Classic or Extreme rubber dog toys. Simply insert Corkz into a stuffed KONG to keep treats inside for non-stop, mess-free chewing and licking. You can then give it to your dog as is or freeze it for even longer chew sessions. Corkz treats are designed to extend your dog's chewing time while also helping to clean their teeth and freshen their breath. Made in the USA, these complementary KONG toppers feature savory, plant-based ingredients that are naturally delicious.
