Andrew, we had a fencejumper who just loved to cross the street and socialize with the teenage skater kids hanging out in the church parking lot. It was a very busy street that she crossed to do so. Eventually we bought a radio collar and buried the cable outside the perimeter of the yard. We put the collar on her every time she went outside and she would get a warning beep as she got close to the fence, then she would stop so othat she would not get shocked if she got any closer. It was really easy to teach her to respect the collar.

It was very effective at stopping her from her fencejumping ways and probably cost us about $150 and an afternoon of labor. The only problem was when the batteries wore out in the collar and then she would wait for her moment to be free!
