Sometimes your dog's health and lifestyle goals demand a protein-centered, grain-free approach to achieving optimum nutrition. Osopure is our answer to that demand. Protein sources of the highest quality are hand-selected to provide a firm base for this special formula; while fruits rich in antioxidants such as apples and blueberries, and vegetables abundant in carbohydrates and fiber such as garbanzo beans and sweet potatoes carefully round out the profile. We all know that a dog's biological design, by virtue of evolution, is based on that of a hunting carnivore. With that in mind, Osopure not only mirrors the balance of nutrition one would find in the wild, it enhances it.
