These are the next best thing from Costco’s pig ears that aren’t always around. Of course these are twice as much from Costco but mine doesn’t have them in stock right now. These ears are great! They are whole ears that are not stale or old. The bag says it’s bio-based and that it’s made out of sugar cane. My pit bull and Dogo recommend these!
