KONG Classic Refillable Ball for Dogs This KONG ball is made from the same durable material as the famous KONG Classic toy. It is just as robust and durable and can easily withstand intense biting and sharp teeth, therefore satisfying dogs' natural urge to bite and supporting dental care. When the ball bounces on the ground, it jumps all over the place and prompts the dog to run after it. The KONG Classic ball is perfect for tossing, rolling, and playing toss and fetch. Your dog can play alone with it, but you can also use it to have a good time together and exercise. Thanks to the hole in its surface, it grips very well, even if it rolls on wet grass and gets wet. Also, through this opening, you can introduce snacks for your dog. KONG Classic Ball is a resistant toy that ensures many hours of fun.
