Unlike a common fence that stands on the ground and more often destroys the look of your yard. An electric or wireless fence does no such thing. There are also referred to as an invisible fence because they can’t be seen. An electric fence has an electric wire that is buried underground, while a wireless fence uses a transmitter which sends a signal to create a barrier. In both cases, a collar is used which corrects the dog by passing a minimal static shock every time he/she goes beyond the limits.
