Using this Purina Pro Plan puppy food is simple. Just follow the feeding guide on the package based on your puppy's age, weight, and activity level. Pour the appropriate amount into your puppy's bowl at regular mealtimes. Remember to always provide fresh water for your puppy. When it comes to storage, keep the bag in a cool, dry place. Once opened, make sure to seal it tightly to keep the food fresh. If you're planning to switch your puppy from another food to this one, do it gradually over a week or so. Start by mixing a small amount of the new food with the old one and gradually increase the proportion of the Purina Pro Plan food. If your puppy has any special health conditions or dietary needs, it's a good idea to consult your vet before starting this food.
