The KONG Classic 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 all-natural red rubber formula is ultra-durable with an unpredictable bounce that is ideal for games of fetch — perfect dogs that like to chew while also fulfilling a dog’s need to play. To extend play time, stuff the KONG with treats, tempting bits of kibble, even a dash of peanut butter. Frozen KONG toys can make playtime last even longer. Available in six sizes: XS, S, M, L, XL, and XXL.
