Patented products, This is an ultra-durable chew stick engineered for power chewers. Its premium, ultra-tough new material can withstand the bites of even the most aggressive dog breeds, ensuring the toy is truly unbreakable and indestructible. The middle section is wrapped in TPR material, catering to dogs that favor soft rubber textures. We have reduced the squeak volume and minimized the sound-triggering area; the subtle squeak retains its appeal to pets without causing any annoyance to owners. This product allows pets to unleash their natural chewing instincts to their hearts' content.
