Top 6 best wire for electric dog fence

Dog owners often wonder whether they should get an electric dog fence or a wireless dog fence. Both options have their pros and cons. Which one would you choose?

Wireless fences are becoming increasingly popular because they don’t require any wires to connect them together. They also allow dogs to roam freely without being restricted by boundaries.

However, these wireless fences come at a price. They are expensive and require batteries that need to be replaced every 6 months. On the other hand, electric dog fences are cheaper and easier to install. However, they do not offer as much freedom as wireless ones.

If your dog is a small breed such as a Chihuahua or Pomeranian, then it may be better to go with a wireless dog fence. If you want more space for your dog, then you can opt for an electric dog fence.

How To Choose The best wire for electric dog fence

Dog fence wire gauges commonly used

In addition to 20-gauge wire (the thinnest), 18-gauge, 16-gauge, and 14-gauge (the thickest) are most commonly used in electric dog fences. The wire used in most prepackaged do-it-yourself fencing kits is 20 gauge.

However, most professionally installed systems use heavier gauge wire, such as 16 or 14 gauge. You can easily obtain a relatively inexpensive and compatible wire for your project, regardless of whether you are replacing a section of your existing fence or installing a completely new fence.

The best wire for burial should be insulated with stranded or solid polyethylene or plastic coating, regardless of gauge. Wire of different gauges and lengths compatible with Invisible Fence® can be found here.

Transmission of signals

Except if you are using a system that is at or near its maximum rated capacity, the gauge of the dog fence wire will not make a significant difference in how the wire transmits the signal. You can achieve a greater range by using a thicker wire in this case. If you use thicker wire, you may be able to enclose 22 acres from a 20-acre system.

It’s a good idea to match the gauge of your new wire to that of the existing wire when you’re replacing a section of wire in your existing dog fence.

By doing so, you’ll ensure consistency of signal across the entire fence. Inconsistent signals can be caused by mixing wires of different gauges, as can false wire break alarms.

Wire that is manufactured by the manufacturer

Each self-install kit includes this wire. With this wire, regardless of gauge, you get lighter weight, lower shipping costs, and medium quality. Despite its capabilities, this wire does not withstand the elements as well as professional grade wire.

Vinyl coatings crack over time and expose the copper, leaving the wire vulnerable to damage. Consequently, your dog fence may not function properly. Due to the difficulty of finding, digging up, and repairing wire breaks, many people prefer to use a high-quality wire from the beginning.


It is believed that thicker wires such as 14 or 16 gauge will be more durable and less likely to break when applied to outdoor electric dog fences.

It is also considered necessary for long term durability by professional installers such as Invisible Fence® and DogWatch®. Compared to a 14 gauge, a 20 gauge is much more durable. A majority of pet fence manufacturers package their systems with low quality 20 gauge wire.

By excluding the heavier wire, the shipping costs and initial purchase price of the dog fences remain much lower than if the heavier wire was included.

Although lower quality wire initially costs less, you will most likely pay for this initial saving in long term maintenance and time consuming repairs over the life of the fence since the thinner wire is more likely to corrode and break.

In addition to wire gauge, chemical compound and coating thickness are crucial factors in pet fences. A vinyl coated wire and a polyethylene plastic coated wire are two types of chemical compounds. A 14 or 16-gauge wire with a 45 mL layer of coating is used by the professionals.

The coating gives the copper an interior layer of solid, waterproof protection, making it significantly more durable than the 20-gauge vinyl coating used by the manufacturer, which is not waterproof.

Regardless of the type of wire you choose for your initial installation, the most significant difference is how often you will have to repair or replace your dog fence wire over time.


The main advantage of thinner wires such as 20-gauge is their workability. It is easier to work with thinner wire because it is more flexible. Consider this if you are making twisted wire sections yourself or if you are routing your wire in an unusual configuration.

Due to its flexibility, thin wire can be twisted and laid much easier. In addition to being more durable, thicker gauges are also stiffer, so they can be more difficult to work with.

Professional Grade Wire

A professional grade of wire is definitely more expensive than a manufacturer’s grade. A pro-grade wire dog fence, however, has many advantages. In addition to holding up better even under freezing conditions, sunlight exposure, contractions and expansions of the ground, and general wear, professional grade dog fence wire is also more durable.

For those who plan to live in their homes for at least 4-5 years, the heavier duty pro-grade wire is a much better investment than the lighter duty wire. Wire for Professional Grade Dog Fences can be found in our store.

Twisted Wire

Used to connect the perimeter wire to the transmitter box, as well as to connect internal ‘no-go’ zones to the rest of the perimeter without defining a boundary line (basically anywhere that the collar should not issue a correction when it senses the perimeter wire). It is possible to buy ready-made pre-twisted wire if you need a long length, or alternatively, you can make your own.

The wire should be twisted one twist per inch when twisting dog fence wire. Because twisting the wire will shorten its overall length, you should start with a piece that is about four times longer than you will need the twisted piece to be.

The wire is folded in half, then the looped end is attached to the fixed point, and then twisted (by hand) or tightened in the grip of an electric drill for a quicker result. Simply cut the looped end of the wire when it has been twisted to release it from whatever you are attaching it to.

What kind of wire do you use for an electric dog fence?

There are different types of wires used in the construction of electric dog fences. The most common type is called “wire mesh”. This type of wire is made up of metal strands which are connected using a special connector. These connectors are usually soldered on the ends of the wire.

Another type of wire used in the construction of an electric dog fence is called “chain link”. It consists of two long chains which are joined together using a special connector.

The third type of wire used in electric dog fences is called “barbed wire”. Barbed wire has sharp points on its edges. When this type of wire comes into contact with the body of a dog, the sharp points pierce through the skin causing pain and discomfort.

What is the best gauge wire to use for an electric fence?

The thickness of the wire determines how strong the electric current will pass through it. A thicker wire will provide stronger protection against intruders. However, if you use too thick a wire, it will make the electric fence difficult to handle.

You can find various gauges of wire available in pet stores. However, the best option is to buy a wire from a professional installer. He will know what size wire he needs to use for each application.

Can I use any wire for invisible dog fence?

Yes! You can use just about any wire for your invisible dog fence. There are many different kinds of wires available. Some of them are even designed specifically for this purpose.

For example, there are some types of wire that are coated with plastic so that they blend in with the environment. They look like rocks or pieces of wood. Others are made out of rubber so that they won’t leave marks on the ground. Still others are covered in a thin layer of paint.

Do Electric Pet Fences Hurt Dogs?

Electric dog fences do not hurt your dog. In fact, they are safer than traditional fencing methods. Traditional fencing methods include barbed wire and chain links. These fences can cause serious injuries to your dog. For instance, barbed wire can cut through their fur and cause painful wounds. Chain links can also cause cuts and bruises.

Electric dog fences don’t have these problems. They are safe because they only emit mild electrical currents. Even though dogs are very sensitive to electricity, they cannot feel the current at all.

How Long Does It Take To Install An Electric Dog Fence?

It depends on the type of installation. If you choose to install a wired system, it will take less time to set up compared to installing wireless systems.

Wireless systems require more work since they need to be installed manually. Also, they must be placed in specific locations.

Installation times vary depending on where you live and the terrain. For example, if you live in a rural area, installation could take longer. On the other hand, if you live in an urban setting, installation may take less time.

Can you use 14 gauge wire for underground dog fence?

14 gauge wire is suitable for most applications. However, if you want to protect large areas, you should consider using 16 gauge wire. This kind of wire provides better coverage.

If you plan to build an underground electric dog fence, you should use 18 gauge wire. This ensures that the fence will stay intact even when buried under several feet of dirt.

Are Electric Dog Fences Safe?

Yes! Electric dog fences are completely safe. They are much safer than traditional fencing methods such as barbed wire and chain link fencing.

Traditional fencing methods can cause severe injuries to your dog. Barbed wire can pierce their skin and cause painful wounds. Similarly, chain link fences can cut their legs off.

On the other hand, electric dog fences are safe because they only produce mild electric currents. Even though dogs can sense electricity, they cannot feel it. Therefore, they cannot suffer any harm.

Can I use stranded wire for dog fence?

Stranded wire is usually used to make fences. However, it is also used to create decorative items such as Christmas lights. Stranded wire comes in various gauges. The higher the number, the thicker the wire.

The best wire for making an electric dog fence is 14 gauge. This wire is strong enough to withstand harsh weather conditions. You can also use this wire to make decorative items.

Is welded wire fence good for dogs?

Welded wire is one of the strongest types of wire available. It is made by welding two pieces of metal together. Welded wire has high tensile strength. This means that it can resist tension well.

However, it does not provide good insulation. Therefore, it is unsuitable for outdoor installations. It is best suited for indoor use.

Can I use Romex for electric fence?

Romex is a brand name for aluminum cable. It is commonly used to make home wiring. It is also used to make electric fences.

You can use Romex to make an electric dog fence. However, it is not recommended. Aluminum cables have low tensile strength. Therefore, they do not last long.

Do Pet Fences Need To Be Installed Underground?

No! Electric dog fences do not need to be installed underground. In fact, they can be installed above ground.

This makes them easier to maintain. You can easily access them from anywhere. However, if you live in cold climates, you might need to install them indoors.

How do Electric Dog Fences work?

The electrical collar placed around your dog’s neck transmits a radio signal to the electric fence. The dog must be trained to stay within the flagged perimeter once the wire boundaries are in place.

Your dog will be reminded to stay inside the boundary of the electric fence with the help of the collar.

A static shock is usually used as feedback, though a warning beep or vibration may be used depending on the collar.

You should remember that these fences are designed to keep your dog within the boundary, but other animals and pets will not be kept out.

This type of fence won’t keep wild animals or neighboring dogs away if they invade often.
