Answer
The fact that she doesn't eat well will control how big she gets.  I would take her to the vet and have her checked
to make sure she is healthy.  Most puppies this age will not eat dry dog food even mixed with water.  I cook hamburger and mix kibble into the boiling water and mix well.  When cool I would offer a small amount of this to the pup.  

A dog can have different kinds of worms that is not visible to the eye.  Have you vet do a fecal check.
