This is an original design product from our company, a pet toy that combines multiple functions such as an automatic retractable ball, a pet yo-yo, and a teething ball. The ball has a built-in retractable drawstring; the other end of the drawstring is looped around the owner's middle finger via a round, soft buckle. After spinning, the ball is propelled far using inertia. The surface of the ball is covered with soft teething bumps of varying sizes, and the hard part of the ball also features various shapes of teething bumps. This allows dogs to clean their teeth while also fostering a bond between owner and pet through interactive play, bringing more fun to the dog's life.
