Jack Russells are high-energy dogs. If not given enough to do, they (and many other dog breeds) have a tendency to give themselves over to unwanted and even destructive behaviors.
Two half-hour walks, and off-leash running every single day. Chasing squeaky balls, a frisbee, even swimming. The more you tire them out, the happier they are.
I would recommend seeing a professional dog trainer to help you train him out of the bad behaviors he's made a habit of.
