The KONG Classic is the gold standard of dog toys and has become the staple for dogs around the world for over forty years. Offering enrichment by helping satisfy dogs' instinctual needs, the KONG Classic's unique natural red rubber formula is ultra-durable with an erratic bounce that is ideal for dogs that like to chew while also fulfilling a dog's need to play. Want to extend play time? Be sure to stuff with tempting bits of kibble and entice with a dash of peanut butter. Add to the fun by adding KONG Snacks and topping with KONG Easy Treat. KONG Wild Knots are soft and cuddly on the outside while durable and strong on the inside. Wild Knots bears are sure to be a hit with dogs and their pet parents. Dogs love the knotted skeleton, and the reinforced plush body provides extra durability. KONG Wild Knots have less stuffing for less mess and they squeak to entice play.
