Toppl® is a treat dispensing, puzzle toy that traps treats inside with its inner ridges to keep dogs entertained and challenged. You can easily interlock the two sizes (sold separately) to change up the challenge for smaller dogs, bigger dogs and clever dogs. Toppl is available in sizes large and small for all sized mouths. Toppl traps treats, doling out sweet rewards one at a time. Toppl falls over tipsily and has an unpredictable bounce! Owners will love watching their dogs chase Toppl just as much as their pups love playing with it! And unlike other treat dispensing dog toys, Toppl is dishwasher safe.
