Keep your pet safe during play. Squeaker, Bouncing, Floating: This toy ball has a built-in squeaker to encourage pets instinctive hunting and play behavior. With its bouncing, 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. < p>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 a dog's natural instinct to chew to massage gums and improve dental health while dogs play. For small to medium sized chewers: the ball comes with a diameter of 6.5 cm, which makes it fun to play when it bounces. Neither too big nor too small, the ball is perfect for puppies and medium sized dogs who like to chew.
