A JRT is the same as any other dog, just...more. If there is one common mistake people make with them (and small dogs in general) is that they treat them differently than large breeds. That is to say, they allow little dogs to do things they would take a dim view of a large dog doing. Terriers (in particular) can become absolute tyrants if you don't teach them good manners, beginning the day you bring them home.
They respond to the same things as any other dog, but typically demand more consistency. Just pretend your JRT is a 90 lb. German Shepherd, and you'll be fine.
