Jack Russell Size

We recently found a small puppy that had been abandoned, just weeks old and we are keeping her in the house. She looks like a JR but she has apparently hit a growth spert. She is getting very tall very fast. Just trying to figure out if she may not be a JR. She's approx 2 months old or so now. How big should a Jack be around this age?

JRT's grow very fast. My male JRT came to me at 9 weeks old and 3 lbs. He's 21 weeks old now and about 12 lbs! He grew 4 lbs at one point in 2 weeks- crazy fast. He was roughly 9 inches or so by the time he was 12 weeks old. Hope this helps!
