Our Whitefish Formula comes from the fish that are found in the cold waters of the Pacific Northwest and Alaska. Whitefish is not oily like Salmon, but it still contains healthy Omega-3 fatty acids, as well as vitamins and minerals for a healthy, happy dog. Whitefish is a rich source of Niacin, Phosphorous, and Selenium. And our recipe is completely grain-free, providing a hypoallergenic option for those dogs that may have food sensitivities or allergies.
