This is a great toy for the active dog.  This has more movement than the average ball because of the grooved sides.  Throw it, bounce it and watch your dog jump and leap for the Huck. This toy is made from zogoflex materials and is 100% recyclable, non-toxic and durable to last.  There are two sizes to choose both in bright colors.  Sizes; Small,2.6",6.6cm, Large3.25",8.25cm.
