Recommended daily amount: 1 1/8 to 1 3/8 cups of a high-quality dog food daily, divided into two meals.

How much your adult dog eats depends on his size, age, build, metabolism, and activity level. Dogs are individuals, just like people, and they don't all need the same amount of food. It almost goes without saying that a highly active dog will need more than a couch potato dog. The quality of dog food you buy also makes a difference--the better the dog food, the further it will go toward nourishing your dog and the less of it you'll need to shake into your dog's bowl.
