From less interaction with you, to lower engagement in daily activities, there are many signs your dog may be aging. Purina® Pro Plan® Bright Mind™ was created out of proprietary research that shows enhanced botanical oils provide an efficient fuel source for the brain in dogs age 7 and older--helping naturally nourish their minds to help them think more like they did when they were younger. 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 require 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. Provide adequate fresh water in a clean container daily. For your pets health, see your veterinarian regularly. Store in a cool, dry place.
