My puppy eats raw but I can tell you that on his 6 month birthday he weighed 73lbs. He is far from being overfed and is slightly on the thin side. He is just a thick boned puppy. I don't believe that he will be much different in ssize then his littermates though. If he looks good then I would not worry about how much he weighs.
There are times when my little guy does not eat. I just take it away and feed him again in the evening. He seems to be growing good
