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.
Draw a plan to indicate the location and size of the underground dog fence. Separate back yard from front by looping fence back on itself at the sides of the house to maintain a continuous circuit.
Use garden flags to mark the desired path for invisible electric fencing. Leave them in place briefly after the underground dog fence is completed to add a visual cue to help the dog recognize the boundary during initial training.
Install the underground dog cable with a gasoline-powered wire trenching machine. Guide the motorized tool along the flag markers to cut a slot in the ground and insert the invisible electric fencing wire at the same time.
Position the slot for the underground dog fencing to avoid edging stones and snap a chalk line as a cut mark. Use a rolling saw equipped with a masonry blade to cut through the asphalt driveway.
Stretch the underground dog fence wire across the driveway and tamp it into the slot with a narrow plastic putty knife that will not abrade or damage the insulating jacket on the wire. Overfill the crack with sealant.
Lay the wire for the underground dog fence as one continuous loop , splicing it as necessary. Widen the slot for the splice, stripping off some wire insulation, joining ends with a gel wire-splice, and burying the device.
Bore an unobtrusive hole near ground level in the garage wall. Fish the two ends of the wire loop for the underground dog fence inside to connect to the transmitter. Caulk around the hole.
Mount the radio transmitter for the underground dog fence to the interior garage wall and attach the ends of wire loop to the terminals. Secure the wire to the garage wall with arched staples.
Plug in the AC power adaptor for the underground dog fence to step-down the voltage of the house current. Check its two lights to confirm the power is working and the loop is continuous.
Put the collar on your dog. Walk your pet slowly towards the underground dog fence until the collar's audio signal is triggered. When the dog turns away, praise it. Approach near enough for a mild static shock, if necessary. Repeat.
