Hills Science Plan Canine Maintenance is for the adult dog from maturity to 7 years old. It is the embodiment of Hills philosophy. In its control of excessive nutrients it sets a standard which makes it different from all other dog foods. It provides all the nutrition the adult dog needs: essential fatty acids for a healthy, glossy coat, high-quality protein to maintain muscles, & sensible levels of calcium & phosphorus for strong bones & teeth. But at the same time, because Hills believe excesses of certain nutrients can eventually be harmful, the levels of phosphorus, for instance, are carefully controlled. With Canine Maintenance your pet will look in the peak of condition throughout a long & healthy life. Ingredients: Beef (min.
