Have you ever wondered what the perfect toy would look like from your dog's point of view? KONG® seems to know the answer. Because the extremely popular KONG® Squeakair® Balls combine two highlights at once: Tennis ball and squeaker. An unbeatable combination! The surface of the tennis ball is made of a special felt material that does not damage the dog's teeth. And the squeaker does the rest to make every day the best in your dog's life. Note: Please never leave the pet unattended while playing. No toy is indestructible. To prevent injuries, the toy should be checked regularly for damage or loose parts and replaced if necessary.
