How to Put in an Underground Dog Fence


Learn how to install an invisible electric dog fence to confine your pet to your yard.

Installing an underground fence to keep your dog confined and safe is a fairly simple project. The fence uses a buried wire that continuously emits a radio signal. Your pet must wear a special collar with a receiver on it and two small prongs/electrodes. When the dog approaches the wire, the radio signal first causes the collar to beep as an audio warning and will then activate the collar to deliver a mild corrective shock to the pet that will cause it to turn back from the fence.
