In the wild, your dog's ancestors hunted and consumed the entire prey animal, including meat, organs, cartilage, and bone, naturally providing them with the nutrients they require for optimal health. Two-thirds of our animal ingredients are FRESH or RAW, and 1/3 are air-dried for a concentrated source of protein. ORIJEN Regional Red is packed with 38% protein from whole animal ingredients from ranch-raised beef, wild-boar, bison, grass-fed lamb, Yorkshire pork, and wild-caught Pacific pilchard, providing your dog with the diet they have evolved to eat.
