Our ultimate Biologically Appropriate freeze-dried food reflects the evolutionary diet locking in all the flavor and nutritional benefits of raw foods, just as Mother Nature intended. Prepared without cooking, ORIJEN Freeze-Dried foods retain the natural goodness of our authentically fresh ingredients. Our award-winning kitchens are equipped with nitrogen tunnels which flash-freeze our fresh regional ingredients at extremely low temperatures (-60F), to retain their life-giving nutrients. Then during a slow 18-hour freeze-drying process, the frozen water is converted directly into vapor, without creating any liquid. This means only water is gently removed from our fresh ingredients, leaving behind richly nourishing goodness in concentrated form, for a taste experience your dog will truly love.Ingredients Chicken (ground with bone), turkey (ground with bone), whole herring, chicken liver, chicken heart, whole eggs, spinach greens, pea fiber, turkey liver, turkey heart, whole flounder, ground whole sunflower seeds, whole pumpkin, butternut squash, whole carrots, whole cranberries, whole blackberries, whole blueberries, apples, pears, plums, apricots, brown kelp, mixed tocopherols (preservative), chicory root, dandelion root, summer savory, peppermint leaf, ginger root, zinc proteinate, iron proteinate, copper proteinate, manganese proteinate.
