We had great success with our invisible fence. Was the only way we could let our short haired pointer stay outside where he wanted to be during the day.

Be sure to replace the collar batteries on schedule. Dogs will test the system by intent or accident and be gone a roaming when they discover "the gate is open."

We got a good laugh when we first installed the "fence." We put up the sign that announced the "Invisible fence" so neighbors and dog catchers would know dog was not running free. Next day we noticed workmen were high stepping over the line of widely spaced tempory flags marking the perimeter as they entered and exited the yard! True Story!
