This is an overview of "visible" or livestock type electric fencing used with escape artist dogs that love to climb or dig.  If you want information about non-visible, underground fencing please  use the link at end of this page.     For visible or wire type electric fences  PLEASE use a fence charger that has an intermittent pulse and ideally a blinking light that shows the charger is working.(note light and "intermittent output" notation on example above.)   Continuous pulse chargers can kill squirrels.....I know it happen to me. I had to get the poor squirrel off the fence and it was dead.   Its front paws wrapped around the wire.  Chargers are made for small animals such as goats and for large animals like cattle.  I use the small animal variety.    You can buy chargers that plug in or that runs off batteries.  Follow manufacture's instructions on placement.   I always place mine where it will not get wet.  There are several different types of chargers and wire available, check with your local farm supply store.  Wire with colored tape is now available and this type wire is easier for dogs and humans to see!  If you have children playing in same area, teach them about the electric fence.  Always have a lightning arrestor on the fence wire!  Properly installed electric fences can be useful tools in containing dogs that love to dig and climb.
You need to keep the grass and weeds off the fence by mowing, weed eating or using a weed/grass killer such as "Round Up" under the wire.  The fence can ground out easily, especially with wet grass.  With high dry grass, some fence chargers could possibly cause the grass to catch on fire.   Also, if the bare wire touches metal it will ground out.  Always test the fence with a fence tester on a regular basis-once a week would be ideal.

CHAINLINK FENCES:  Insulators are made to latch onto the fence.  Typically they extend enough for wire to clear standard fence post.   For diggers place them low on the fence.  For climbers place them higher on the fence; approximate the height of the beagle standing on its hind legs and place where chest would touch fence.

PRIVACY FENCES:  The insulators nail onto the fence at the level of of bottom support board.  You need it to stand out a few inches from the fence for best anti-dig protection. For a jumper or climbers place the wire about mid-height of the fence.  Below is pictures of my fence, note the small insulator that were too short to work adequately.
