PREMIUM AND SAFE MATERIAL: This training and interactive toy is made of food grade, non-toxic, soft TPR (BPA free), which makes it not easy to break and the spikes on the surface of the ball prevent your puppies to choke. Keep your pet safe during play. Squeaker, Bouncing, Floating: This ball toy has a built-in squeaker to encourage instinctive hunting and play behavior in pets. Meanwhile, with its bouncy and floating design, it can play toss and fetch games with pets on the lawn, ground, lake or swimming pool, which enriches human and animal bond. IMPROVES DENTAL HEALTH: The unique shape with spikes helps prevent plaque and tartar buildup when dogs chew. At the same time, it tends to satisfy the dog's natural instinct to chew to massage gums and improve dental health while dogs are playing. For small to medium sized chewers: the toy comes with a diameter of 6.5 cm, which makes the game fun when it bounces. Neither too big nor too small, the ball is perfect for puppies and medium-sized dogs who love to chew. Perfect gift for your pet: 12-month warranty and lifetime customer service.
