Jack Russell sizes.

I have 2 JRTs, brother from 6 months older little, and little sister. Names are Darcy and Sofie. Darcy is turning one this month, and Sofie 6 months. She is much smaller than he is but holds her own in their crazy games. Will she get a lot bigger. Darcy was much larger at her age.
