With 38% richly nourishing protein and a limited 18% low-glycemic carbohydrates, Orijen USA Regional Red Grain-Free Dry Dog Food nourishes all breeds and life stages according to their evolutionary and biological needs. This formula provides fresh angus beef, wild boar, plains bison, Romney lamb, and Yorkshire pork. Unmatched by any other dog food, 2/3 of Orijen meats are fresh (refrigerated, no preservatives) or raw (flash-frozen, no preservatives). The remaining 1/3 of meats are air dried at 90 degrees Celsius from fresh red meats and fish to create a concentrated source of richly nourishing protein that cannot be supplied by fresh meats alone. The nutrient-dense WholePrey ratios of fresh meat, organs, and cartilage provide virtually every nutrient your dog needs to thrive - only zinc is added. Infusions of freeze-dried liver enhance flavor naturally, making Orijen deliciously tasty, even for fussy eaters.*Approximate and derived from the unprocessed state of the ingredients.
