KONG Holiday Occasions Tennis Balls (Medium, 4-Pack): A set of four durable tennis balls decked out in holiday prints (like snowflakes, reindeer, etc.) to add seasonal flair to fetch games. These balls have the same reliable bounce and felt exterior as KONG’s regular tennis balls, but are printed in limited-edition festive designs. They contain squeakers for extra fun – each time your dog catches or squeezes a ball, it rewards them with a delightful squeak. Perfect for dogs that can’t get enough of fetch, this 4-pack ensures there are plenty of spares for indoor or outdoor play. Toss them during holiday gatherings to give your dog some exercise and show off their holiday spirit with every fetch and squeak.
