Dogs evolved as hunters – the structure of their teeth, jaws and digestive system scientifically classifies them as carnivores, evolved to eat a meat-based diet. They require high concentrations of meat or fish, high inclusions of fresh meat, and a rich diversity of meat.FISH AND PROTEIN RICH Loaded with 85% wild-caught fish ingredients, ORIJEN Six Fish features a richly nourishing and Biologically Appropriate™ protein level of 38% to replicate your dog’s natural diet. RICH IN ESSENTIAL FISH OILS For amazing skin and coat conditioning, ORIJEN’s unique WholePrey™ ratios of fresh fish are naturally rich in essential fatty acids, including Omega-3, DHA and EPA that are not available from plant sources, such as flax, coconut or sunflower. LOW GLYCEMIC Your dog’s natural diet contains few carbohydrates. That’s why ORIJEN is free of high-glycemic ingredients like potato, tapioca and starches, and contains half the carbohydrates of conventional dog foods. GLUCOSAMINE & CHONDROITIN ORIJEN’s high WholePrey™ ratios of fresh fish provide a rich and natural source of glucosamine and chondroitin, derived naturally from our fresh ingredients, so no synthetic sources are added to ORIJEN foods.
