"Orijen Senior Dog is formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles for All Life Stages.By nature, dogs of all breeds and sizes are evolved as carnivores. Biologically adapted for a diet rich and varied in fresh meats, with smaller amounts of fruits, vegetables and grasses.Yet as dogs age, they also become less efficient at metabolizing the very proteins vital to their well being. So appropriately high levels of dietary protein is essential for enabling your senior dog's peak conditioning.That's why we load Orijen Senior with the protein-packed animal ingredients (85%) that Mother Nature evolved all dogs to eat, with high ratios of free-range chicken and turkey, whole eggs and wild-caught fish, farmed or fished within our region and delivered fresh each day so they're preservative-free and brimming with proteins and fats to nourish your older dog completely.Carbohydrate-limited and grain-free to replicate your senior dog's natural diet, Orijen Senior supplies healthful regional fruits, vegetables and botanicals, including sea vegetables, juniper berries and turmeric; naturally rich in phytonutrients, B-vitamins and essential trace minerals.
