I am wondering if she could be a different breed then you were told if you feel she is so small. As long as she isn't sick then it is just her and she may not get so big. If you are concerned I would discuss this with your veterinarian and they can evaluate her to see if she is a healthy pup. Thank you for using Petco Pet Education Center, formerly Petcoach.
