Dog Fence Wire

The most significant part of your dog fence system, the grade of fence wire that you select should be contemplated carefully. When you are deciding what in-ground dog fence wire you should buy, the first aspect to consider is the gauge of wire that it is. This is because the gauge of the wire you choose establishes its durability and how long you can expect the system to last.

What Is Dog Fence Wire Gauge?

When you hear talk about the gauge of a wire, it refers to the thickness of it. The lower number of gauge that the wire is, the thicker that it is. Wondering why this matters? The thicker the wire is, the stronger it will be over the years against the natural elements. Under pressure, the thicker wire is less likely to bend or break. Most electric dog fence kits come standard with 20-gauge dog fence wire, which is quite thin. In contrast, most systems that are installed professionally use a stronger 14 or 16 gauge wire.

How to Select the Right Gauge of Wire

The gauge of wire you select won’t impact the way the wire transmits the signal to the receiver collar, unless you are using the system at its highest-rated capacity. If this is the case, a thicker wire may actually increase the range you can get with your system. For example, if you use a heavier gauge wire, you may be able to get extra acreage out of it.

If you need to replace a section of your dog fence wire, be sure to match the gauge of your wire with the wire that you already have. This will ensure that your signal will be consistent throughout the entire fence. If you mix the gauges of wire, you may experience problems with your transmission such as inconsistent signals or a false wire break alarm.

Durability of Dog Fence Wire

When you choose a heavy duty 14-gauge dog fence wire, this will allow you added durability over time. Standard grade wire is of medium quality, a lighter weight and is geared to allow shipping charges and initial setup costs to be lower. Although this standard wire will work for your system, it will not withstand the elements like a professional grade wire can.

On cheaper manufacturer wire, it has a vinyl coating that is prone to cracking. Over a period of time, the copper becomes exposed, which leaves the wire vulnerable to damage. This can make your electric dog fence not function as well. It is quite tedious to have to locate, dig up and repair a wire break. This is why many people decide to save themselves a headache and get the better quality wire in the beginning.

Even though it costs more initially to purchase the professional grade wire, there are many reasons why it is advantageous. Professional grade wire is designed to withstand freezing conditions, sunlight and water exposure, general wear and tear and the effect of the contraction and expansion of the ground.

Professional dog fence installers either use a 14 or 16-gauge wire with a coating thickness of 45 mm. The coating on the wire gives the copper inside a waterproof means of protection. The coating that is on the standard 20-gauge wire is not waterproof. In the long term, the money and time you will save buy installing the professional grade wire in the first place is well worth the extra cost.


The only benefit to using a thinner, 20-gauge dog fence wire is its work-ability. The thinner wire is going to be more flexible and easier to manipulate. This is something you should consider if you are burying your wire in a precarious arrangement. As it is more flexible, it is much easier to twist and lay a wire that is thin. A thicker gauge wire is heavier and stiffer, so it may be a bit more challenging to work with.

Twisted Dog Fence Wire

Twisted wire serves as the means to connect your boundary wire to the transmitter box. You can also connect areas where you don’t want your dog to go to the rest of the perimeter without having to form a boundary line. You use it anywhere you don’t want the wire to trigger a stimulation. Using pre-twisted wire is the best decision if you need a long length of it. We also sell lengths of twisted wire so that you don’t have to twist it yourself.
