The weight chart is not always right on it really depends on the lines from which your dog comes from, and 5 weeks is a little young to be guestimating. If you are that worried about size I would look at a dog that is an older puppy, but even then there is no way to guarantee the adult weight. I also second that 5.5lbs is by no means big, it is actually a really great size still very small and portable but you don't have to worry about them every second.
