From what Ive read on this board, you take thier 12 week old weight and double it, but that isnt always accurate. My pup's parents were 4 and 4.5 pounds and at 18 weeks he already weighs 5 pounds. So it really is hard to tell. Being that your pup is that little still I wouldnt think that it will get bigger than 4ish pounds.
