When you order an electronic dog fence, whether Innotek or Petsafe brand, it comes with a 500 feet of 20-gague wire which is necessary in creating the boundary of your fence. And in case you want to cover a large area, you can easily do it since each kit includes all the things you need to expand the coverage.

WIRE GUIDE:

Size of Yard	Length of Property Line	Extra Boundary Needed
Between 1/2 and 1 Acre	Between 500 and 1000 feet	1
Between 1 and 3 Acres	Between 1000 and 1500 feet	2
Between 3 and 5 Acres	Between 1500 and 2000 feet	3

Use Only Burial Approved Boundary Wire

Choose only Burial Approved wires for long lasting durability of your fence system. This type of wire will not get damage easily. And for effective containment fence, use only waterproof Polyurethane Coated wire with solid copper core.

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

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

Use 18-Gauge if:
» Rocky soil
» You are installing your wire above ground
» Your yard has many trees

Use 20-Gauge if:
» You have smooth, loose soil or clay
» You are laying your wire next to a fence
» Your yard has few trees or vegetation.
