This KONG toy is even more challenging than a licking mat! Because the toy has a weighted and rounded bottom, it wobbles when a dog licks it, without falling over. The different textures make applying tasty spreads (such as peanut butter or pate) very easy. The dog has to try hard to lick all the goodies off the wiggling toy. Ideal as a reward or to combat boredom and anxiety. The toy is easy to wash by hand.
