I don't think there can be a definitive chart of how much food to feed a puppy because it will vary so much by brand and contents of the food. Many of us use the body condition chart as a guide and you want to keep your puppy on the lean side. My vet prefers a 4. With a growing puppy you will need to assess often and adjust the amount accordingly. With a fluffy puppy you need to feel for the ribs and look at them from the top when they are wet.
