Leave it to [Lou Wozniak] to go beyond ordinary when installing invisible fencing. Invisible fence is an electronic system that contains your dog by triggering a shock collar. The install requires a loop of wire to generate a field detected by the collar.
[Lou] starts off by buying a do it yourself kit. He has previous experience with this (check out his battery hack for the collars) and found that the cheap solid core wire didn’t hold up to animals and shovel accidents. He headed down to the hardware store and came back with a spool of stranded wire with extra thick insulation which should hold up much better.
The image above shows the model he built to plan for the installation. He’s not just making a single area in the yard. Look closely and you’ll see he’s going to use it to keep the dogs out of the dining room as well. This loop will be installed just below the floor from the basement.
With planning behind him he doesn’t fail to innovate with the installation technique. He recommends an angle grinder with a diamond blade to cut the slot for the wire in your yard. The one caveat being that you need to wait until the yard is super dry or it will muck up the blade. Dry dirt creates a lot of dust, but he uses a leaf blower or floor fan to blow it away from him as it works. To help minimize the amount of shocks the dogs receive while learning their new area he placed some white rope above the wire run as a visual cue.
