Your puppies nutritional intake will vary as they progress from stage to stage.  When you first take your puppy home it will be a time of big changes.  They may not eat well for the first day or two.  I would recommend having some beef broth on hand to use if needed..  

As your puppy grows and develops sometimes people have a difficult time telling if their puppy is the correct weight, especially if they have a LOT of coat.
Run your fingers across the top of your puppies spine.  You do not want to have your finger dip each time it comes to a new rib bone. And at the same time you want to be able to feel the spine.  Over feeding your pup will cause hip issues.  Under feeding is also dangerous and can compromise their overall health as well. 

Your puppies nutritional intake will vary.  Your puppy in the beginning the first day or so may have a decreased food drive due to all of the changes taking place.  Usually breakfast and dinner are the biggest meals for them and lunch is usually a little less.  But once they are in a home and active it will increase.  Once your puppy reaches 4 months of age you can start moving them to twice a day feedings am and pm.  My adult dogs range between 1/2 -1 cup twice  day.  You will have to see whats right for your puppy.
