BIOLOGICALLY APPROPRIATE | FOR SENIOR DOGS FRESH FREE-RUN CHICKEN AND TURKEY, NEST-LAID EGGS AND WILD-CAUGHT FISH SENIOR DOGS ARE BEST FED A DIET RICH IN PROTEIN TO PROMOTE LEAN MUSCLE MASS, YET LIMITED IN CALORIES TO PROMOTE A HEALTHY BODY WEIGHT. With 38% richly nourishing protein, and a limited 19% low-glycemic carbohydrates, ORIJEN nourishes all senior dogs according to their evolutionary and biological needs. Unmatched by any other senior dog food, 2/3 of meats are FRESH (refrigerated, no preservatives) or RAW (flash-frozen, no preservatives), including the top 10 meat ingredients. 1/3 of poultry and fish are prepared at 90Ã¯Â¿Â½C from fresh chicken, turkey and fish to create a concentrated source of richly nourishing protein that cannot be supplied by fresh meats alone. Nutrient-dense WholePrey ratios of fresh meat, organs, cartilage and bones plus fresh whole fish and fresh whole eggs provide a natural source of virtually every nutrient your senior dog needs. Infusions of gently freeze-dried liver enhance flavour and palatability naturally, making ORIJEN deliciously tasty, even for fussy eaters.
