The PetSafe® Ribinator Dog Toy is a durable, treat compatible dog chew toy. The large rubber tubes and nylon supports make the toy long lasting. It also helps stimulate and engage your best friend for enhanced playtime. The hard chew strength makes the Ribinator a great addition to your dog’s toy collection, even for the most energetic chewers. Bully sticks, treat sticks, smearable treats, and even treats or food from your pantry can be utilized with the Ribinator. Tailor how quickly treats dispense with the Treat Meter® by simply trimming the prongs. We recommend trimming the Treat Meter prongs just a little at a time to achieve desired results.
