The Starmark Treat Ringer Dog Toy is an extremely durable interactive toy that will keep your pup mentally and physically engaged. Both the Ringer Horseshoe and Ringer Orb hold Starmark Edible Rings that fit onto the inner loop of the toy. They can also fit sideways between the outer wall and inner loop. It’s a fun way for your pup to keep his mind active as he bites the treats and tries to remove them one by one. The Starmark Treat Ringer encourages non-destructive chewing, which alleviates boredom and is also great for your dog’s dental hygiene.
