Puppies should be eating food labeled for growth or for all life stages. After a month or six weeks on the food, assess your puppyâs health. He should be playful and energetic, with a shiny, thick coat. Formed brown feces are a sign that your puppy is digesting most of the nutrients in the food. Puppies should eat three times a day from weaning through four to six months, if possible. After six months, twice-a-day feedings are fine. But if youâre not able to feed your pup three times a day, donât worry. Buffington says puppies can adapt.
