My prediction is that they will need a tiny bit of an adjustment period and then they will be best friends and you will wonder if your Jack Russel even remembers what it was like before your Yorkie arrived. My brother has a Jack Russel and I have taken my lil guy over for visits. My pup loves Jesse but it takes Jesse a while to get used to the pup each time....different tempraments for sure. They will balance each other out, you'll see.
