The product is a pet toy that interacts with the main pet and integrates multiple functions such as automatic telescopic hand-throwing ball, pet yo-yo, molar ball, and so on. The hand throwing ball has a built-in retractable drawstring, and the other end of the drawstring is put on the middle finger of the owner through a round soft rope buckle. After rotating, it is thrown with the help of inertia, and the ball can be thrown far away. The surface of the sphere is arranged with different sizes of soft molar convex points, and the hard-sphere also has a variety of different shapes of molar points. Let the dog not only clean the teeth, but also cultivate the feelings between the owner and the pet in interactive play, and bring more fun to the dog.
