A puppy's nutritional needs depend on many different factors, such as its individual growth rate and appetite. A veterinarian can assess all the factors and give you personalized advice regarding the type and amount of food to feed your puppy. Forcing a puppy to eat more or less than it needs will lead to poor health.
Dog food packaging can give you a general idea of how much food your puppy is likely to require, but your specific dog may have different needs. The website Pet Education recommends getting a veterinarian's advice about the best type and amount of food for your puppy.
