Use Only Burial Approved Boundary Wire

Keep in mind that the wire used in setting up the underground dog fence is Important. Burial Approved wire is more preferrable. Use only long lasting waterproof Polyurethane Coated wire with solid copper core.

Should I Use 18-gauge or 20-gauge wire?

Manufacturers of underground dog fence systems recommend using 20 gauge wire with their systems because the systems are designed to be used with the same gauge wire. We ship all of our containment systems with Premium, Heavy-duty, 20 Gauge Wire. If owners want an additional 500ft. of 18-Gauge with the system, we offer a WIREUPGRADE option, which can be purchased with any containment system. Please see underground dog fence below to determine the proper gauge of wire. Remember, 18 gauge wire cannot be purchased from the local pet store or pet supply catalog.

Use 20-Gauge if:
» For smooth, loose soil or clay
» If laying the wire next to a fence
» If yard has few trees or vegetation.

Use 18-Gauge if:
» Rocky soil
» If installing the wire above ground
» If yard has many trees
