We have two whippets (35 lbs each) and bought the x-large so they could both fit, which they do. I would suggest maybe getting the medium so your Jack Russell feels she has room to go deep in the cave and turn around.

I first bought the 25" small bed for my guys, they are big Italian Greyhounds, one is 21lbs (8mos) and the other is 17lbs (10most), and they can each fit very well inside the small bed. It's cozy and they curl up in there with wiggle room to spare. I just bought the Large one because I wanted them both to fit inside, and when there's only one in there he can stretch out and even play around in it. I uploaded them in the Large one in my review of this bed, and here I will upload them both in/on the small one. Hope this helps!
