Dogs need omega-3s in their diets in order to stay healthy. Nordic Naturals Pet Cod Liver Oil is made from 100% wild Arctic cod to give your dog the daily serving of omega-3 EPA+DHA it needs to live an active, happy life. Nordic Naturals Pet Cod Liver Oil does not contain rosemary oil, or flavorings, in order to ensure the safety of your dog. Please do not give our products for people to your dog. Thank you!
