JW® Tumble Teez  is designed to sporadically dispense treats as your dog plays with the toy. Intelligently designed; the Tumble Teez has a patented internal shelf design that works like a maze for the treat to travel through as your dog nudges and paws at the toy. This challenging puzzle dog toy is designed to keep your dog engaged and makes treat time last longer. Made of natural; non-toxic rubber and constructed with a super thick rubber wall; the Tumble Teez will stand up to all the fun your dog unleashes. PRODUCT NOTE:Supervised play will help toys last longer and most importantly keep your pet safe. No dog toy is truly indestructible; so always remove the toy from playtime if pieces begin to break off.
