The brightly colored tennis ball fabric is non abrasive and gentle on the teeth and gums. Squeaker units are hidden and covered by a durable tennis ball fabric for a clean, finished look. Happy Birthday and a party pooch image is stamped on the surface of all three balls. Established in 1976, KONG has since become the standard for dog toy performance and durability. Their products are recommended by veterinarians, trainers, dog professionals and customers worldwide. Not recommended for use in the water.
