This lamb and fish dog food is formulated to meet the nutritional needs of medium and large-breed ADULT DOGS. To keep their SKIN and COAT healthy, we have added an optimal ratio of omega-3 and omega-6. Since large breed dogs are more likely to develop joint problems, we have also added glucosamine and chondroitin to protect their cartilage and joints. This formula also contains prebiotic fiber to regulate bowel function and improve stool consistency. A unique combination of antioxidants helps limit inflammation and slows down the consequences of early aging and cognitive decline. When fed throughout adult life, this formula is an effective preventive strategy that boosts the immune system, promotes overall health, and gives your dog a beautiful coat!
