Ethically sourced and made from 100% South American beef esophagus. These chews have a flat, “jerky-like” texture and shape. The esophagus is a unique source of chondroitin and glucosamine, which both promote healthy joints. Easy to digest, high in protein, and low in fat. No additives, fillers, hormones, chemicals, or preservatives. Our Natural Animal Part Treats are distributed from Warehouse #4 which is a FDA/USDA certified warehouse that strictly deals with food. As a result you may experience a small time lag with when that component of your shipment leaves the warehouse. We pride ourselves on fast delivery but safety takes precedence over speed. Please be patient as some parts of your shipment may arrive before others.
