Leonard Powell, the legendary founder of Hi-Tek Rations, has been formulating the world?s best animal foods for nearly a third of a century. This family of foods provides your dog with nutrition for great health and vigorous living in three groups of foods: Exotics, featuring bison and duck; Classics, featuring chicken and pork, and Baked, offering chicken and lamb in an oven baked recipe. The bison has long been king of the range and prized for its low fat, grass-fed muscle. The first ingredient in the Exotic Grain Free Bison Formula is bison, and includes apples, carrots, tomato pomace, blueberries, pre-and probiotics, and omega-3 and omega-6 fatty acids including DHA.
