Aristopets Pork Swallow's are the trachea and esophagus combined, and they have been slowly dehydrated to create the perfect crunch and irresistible, juicy flavor. These single ingredient chews are fully digestible and for dogs of all sizes. Swallow's are a great source of glucosamine and chondroitin, which comes in handy for joint issues. These chews are also high in natural proteins, yet low in fat. Aristopets Pork Swallow's come from a local, fresh farm and are dehydrated right here in our pet store. There are absolutely no added fillers, preservatives, colors, or chemicals.
