This is a patented product featuring double reinforcement, excellent shatter resistance and ultra-strong chew resistance. Adopting the production process of wrapping rigid ABS with soft TPR rubber, the toy is designed with striped molar bumps on the surface. Combined with the internal rigid ABS structure, it can better clean dogs' teeth during chewing. Equipped with three built-in sound devices, the ball emits sounds of different volumes that are smooth and long-lasting when moved, effectively attracting dogs' interest. It helps dogs pass the boring time and reduce anxiety.
