With Eukanuba's Senior Small Breed formula you'll see optimal results with this specially formulated weight-control diet, as older, less active small breed dogs are prone to weight gain. As your small breed dog enters his senior years, controlling your dog's weight can help protect against health effects such as diabetes or joint stress. Eukanuba Senior Small Breed contains a reduced fat level that still offers fish meal and essential nutrients for skin and coat health, L-carnitine, a key nutrient that helps burn fat and maintain muscle mass during weight loss, and special carbohydrate blends that help maintain energy while managing weight.
