Dogs evolved as hunters and adapted to a meat-based diet that’s rich in animal protein and fat. Biologically appropriate Orijen Dog Food is uniquely different in that it is protein-rich, carbohydrate-limited and grain-free, featuring the highest fresh meat inclusions of any dry dog food, at the same time excluding many conventional pet food ingredients – such as inappropriate high-glycemic cereal grains and vegetable proteins that simply are not present in the natural puppy, senior or adult dog food diet. The Orijen biologically appropriate ratio is 80 percent meat, 20 percent fruits and vegetables, and zero grain (80.20.0). By mirroring the foods that dogs evolved to eat, the Orijen puppy, adult and mature dog foods result in the peak health and happiness of your cherished pet.
