Your puppy is being raised on Purina Pro Plan Savor Puppy.
Dog food is a very personal choice, and you should do your research before switching brands. There is some recent evidence that “Grain-Free” foods MAY not be the best choice for dogs. Most people, including your average veterinarian, are NOT NUTRITIONISTS. The scary part is they often pretend to be. Be your puppy’s advocate and make sure you are comfortable with the food you choose… and there is nothing wrong with switching foods!
