Patented products, This is an extremely durable chew stick designed for aggressive chewers. Its ultra-tough new material can stand up to even the most powerful canine breeds, ensuring the toy remains intact and undamaged no matter how hard dogs chew. The middle section is wrapped in TPR material, catering to dogs that prefer soft rubber textures. We have reduced the sound volume and minimized the sound-triggering area; the gentle squeak retains its appeal to pets without causing annoyance to their owners. This product allows pets to unleash their natural instincts to chew and play to their hearts' content.
