We recommend that you keep your dog in ideal body condition and not allow your dog to become overweight. The exact amount of food your dog requires will need to be adjusted according to age, activity and environment. But a good place to start is with these guidelines for an average, active, adult dog fed once daily. MAKING THE SWITCH TO PRO PLAN Although you'll be anxious to see the difference Pro Plan can make in your dog, please allow 7 - 10 days to ease the transition from your dog's current food. Each day, simply feed a little less of the previous food and a little more Pro Plan until you're feeding Pro Plan exclusively. This gradual transition will help avoid dietary upsets.
