Congratulations, your puppy is officially an adult. Your tender loving care and Purina ONE Healthy Puppy Formula have turned him into a strong, healthy dog. He no longer needs the extra calories and nutrients he required during his growing stages, so it's time to make the transition to a high-quality adult food like Purina ONE TOTAL NUTRITION Chicken & Rice Formula.

Start by mixing the new food with the previous food, and gradually increase the proportion of the new food. The complete switch should take 7 to 10 days.
