Qwizl� is our new interactive treat-dispensing toy that keeps dogs stimulated and pleasantly puzzled. Its brilliant design extends the life of expensive dog treats while prolonging play to keep dogs interested in their own snacks and away from shoes. Qwizl is also great for interactive play so go ahead and toss it after the treats are gone. Check out the best treats to stuff inside Qwizl. Qwizl is available in two sizes, small and large and available in West Paw Design�s classic, easy-to-spot colors, Aqua, Tangerine, and Granny Apple.
