These 12-inch Stuffed Gullet wrapped with beef bladder makes incredible treats for medium to large size dogs (or even the small dog with big dog syndrom). It combines the long-lasting chew of a gullet with a tasty, soft inner composed of beef offal (organ meat which is great for dogs!) and bully stick flour (ground bully stick). Our dog will love working through the hard exterior to get to the soft, tasty inner treat. They contain no additives or preservatives and are sourced from free-ranging, grass-fed South American cattle.
