The KONG Stuff-a-Ball is a wild-bouncing, rubber "ball" and a dental cleaning device all in one. it's designed to hold treats that dispense as your dog rolls the ball, chews, and plays. Extracting the contents becomes a hunt to keep any pooch happy and busy for hours while you're away, especially those with separation anxiety or problem behaviors. Perfect for stuffing with KONG Stuff’N Snacks or for filling the patented Denta-Ridges with KONG Stuff’N Easy Treat paste.
