The diet for a healthy, adult dog aged one to six years old is called a maintenance diet. Unless your dog is pregnant or nursing, a high-quality, complete and balanced maintenance diet is just what the doctor ordered.

Of course, the quality of ingredients and the digestibility of the food will determine how much nutrition actually stays with your dog and how much simply passes through as waste. So your best value is to choose a nutrient-dense, highly digestible formula like Purina ONE TOTAL NUTRITION Chicken & Rice or Lamb & Rice. Each formula contains real meat or poultry as its number one ingredient. There's even a Purina ONE Large Breed Adult Formula (for dogs weighing over 23 kilograms). It's scientifically formulated to help support joint health and maintain lean body mass for ideal body condition.
