Orijen Puppy Food is specifically made to support the growth and development of small and medium breed puppies. Dogs are natural carnivores and need Biologically Appropriate* recipes that suit their evolutionary, nutritional requirements. This recipe, with 85% meat protein content, is made to suit just this. Protein comes from a variety of meat sources including free-run poultry, wild-caught fish, and nest-laid eggs. Orijen stands apart from other brands because 2/3rds of the meat used is fresh or raw (without any preservatives). In order to control quantity, all their ingredients are regionally sourced and prepared in their own, award-winning kitchens. Nutrient-dense WholePrey ratios of meat, cartilage, and organs are used so your pup has access to vitamins & minerals from natural sources. The only added supplement is zinc.
