Jack Russell size

Hello
I recently got a 1-month old JR. Now she is 4 months, weights 4.5 lbs. Alot of people tell me she is small for her age and think that she is a miniature. However, the owners told me she is pure. What is the average size of JR at this age? Can they be smaller without being a miniature?
Thanks.
