High Quality & Safe Material: This interactive and training toy is made of soft, non-toxic and food-grade TPR (BPA-free), which is not easy to break and the spiked pad on the surface of the ball prevents puppies from choking. Keep your pet safe while playing. Squeak, Bouncing, Floating: This toy ball has a built-in squeaker to encourage pets' instinctive hunting and playing behavior. Meanwhile, with its bouncing and floating design, it can play fetch and throw with pets on the lawn, floor, lake or pool, which enriches the human-animal bond. Improve Dental Health: The unique spiked shape helps prevent plaque and tartar buildup when dogs chew. Meanwhile, it tends to satisfy the dog's natural instinct to chew to massage the gums and improve the health of the teeth while playing. For Small and Medium Chewers: The ball is 6.5cm in diameter, which makes the game fun when it bounces. Not too big, not too small, the ball is perfect for puppies and medium dogs who love to chew.
