The shape and thickness will vary but we try and classify them with a diameter of approximately the size of a quarter minimum and length will be between 6 and 9 inches. When the pieces get smaller you would have to discard them so they do not pose as a choking hazard. As always, it is recommended that you supervise your dog when any treat is provided. Ensure fresh water is available. A great chew for indoors not messy like bones. We recommend that your dog grinds down no more than an inch per day.
