This ACORN is made for those who loves to chase and a squeaky ball! The oval shape of the acorn makes it roll funny and inside it is a durable TPR ball that squeaks and massages the canine mouth.Approx. 3″ x 4″ or 8 x 11cmEach pup plays differently and we recommend you to keep a close watch particularly during the first time a new play object is introduced. No toy is completely indestructible, so please supervise the play to ensure safety if you know your pup is not gentle with toys.
