Invisible Fence

An invisible fence is a fence designed to restrict a dog from leaving the property while not requiring a homeowner to build an above ground fence. An invisible fence has an electric wire that is underground around the perimeter of where the owner would like the dog confined. A receiver on the dog's collar beeps as the dog nears the invisible fence and gives a mild electric shock if he gets too close.

The advantages to an invisible fence are that it improves the appearance of a person's yard and yet the dog can not leave the property. The disadvantages of an invisible fence is that it does not keep people or other dogs out of the yard, and if a dog wants to leave, it can endure the pain of crossing the invisible line and then go free. Nevertheless, these fences tend to be highly effective.
