Double Loop Layout

How to Install an Electric Dog Fence on less than 4 sides or a driveway

You can run the wire in a way to block just 1 or 2 sides of a boundary, or just a driveway. This is less secure, as often when the main escape route is block, they look elsewhere. It can also use the same amount, or more wire than covering all sides.

Double-Loop Layout Explained

The double-loop installation uses a single boundary wire running down 1 or 2 sides of the boundary, and then doubles back to return to the transmitter to complete the loop. Where the zone needs to be active (stopping the dog escaping), the two parallel wires are recommended to be at least 1m apart. As the two wires come closer together, the signals coming off each wire will cancel out.

The boundary wire creates a radio signal field detected by the dog’s collar. As the dog approaches the boundary, warning tones and correction levels guide them back into the safe zone. This zone is adjustable, typically from a few centimetres out to about 3m (depending on how close the two wires are).

Corners should be smooth rather than sharp angles, and the wire must always return to the transmitter to complete the electrical circuit.

1. Choose Transmitter Location

Place the transmitter inside a garage or sheltered area with power access. The boundary wire will start and finish here, forming a complete loop.

2. Run Wire to Boundary

Run the wire out to the section you need to block. Often, the shortest, direct path is best. This section may need to be buried. The easiest way is with a shovel, create a shallow slot in the ground to sit the wire in (5-10cm). It doesn't need a trench.

3. Lay Wire Down the Sides You Need To Block

Run the wire along the section you need to block. If there is an existing fence, the wire can be attached to it. If there is nothing to attach to, it is best to bury using the same shovel technique above.

4. Driveways and Gateways

If the wire needs to cross a driveway, bring the wire to the ground to bury across. If the driveway is gravel or dirt, dig a small section and run through some thin PVC pipe or rubber hose for added protection.
If the driveway is concrete or bitumen, there may be an expansion joint nearby to sit the wire in, or you may need to cut your own slot with an angle grinder. See more tips on running the wire here.

5. Complete the Loop

Return the wire back along the same path as the first wire. You will need to keep the wire at least 1m apart from the first wire where the signal needs to be active. This can be vertical (top of fence, bottom of fence) or horizontal on the ground. Twisting the return wire around the lead out wire will cancel out the signal in this section, allowing the dog to go near the twisted section without the collar activating. Electric dog fences only work when the circuit forms a continuous loop.
