Thank you for viewing my products. These are dog tennis balls with an adorable logo that seems to say "Throw the ball!" They come in a wide range of sizes, from XS for small dogs to XXL for even super-large dogs. With a 3mm thick natural rubber layer and felt fabric, they are gentle on your dog's teeth and are also strong and durable. For active dogs, whether at home, at the dog run, or in the park. ●XS Size: φ47mm/pc ●Material: Polyester, Rubber [About this product] This product is a dog toy.
