Electric Dog Fence Reviews, & Comparison Guides


Types Of Electric Dog Fences

There’s three main types:

  • In ground/invisible dog fences (where the perimeter wire is buried)
  • Above ground dog fences (where the perimeter wire can be left exposed above ground – these tend to be the 14 gauge wire fences with the thicker poly coating wire jackets)
  • Wireless dog fences

There’s also several types of specialty dog fences for tiny dogs (with collars for the smallest dogs/ necks), for stubborn dogs (with stronger correction stimulation), and so on.


In Ground vs Above Ground vs Wireless Electric Dog Fences

The main difference between them is that firstly, in ground and above ground dog fences tend to be more reliable and better performing.

And secondly, above ground dog fences are easier to install than in ground systems. 

A wireless dog fence doesn’t use wire, but rather has a circular signal emitted from the transmitter which acts as a perimeter.

Factors To Consider In Deciding Which Electric Dog Fence To Buy

It depends on your yard, your pet/s, and your personal wants and needs.

But, some of the main considerations you may take into account when deciding on what dog fence system to get might include (but aren’t limited to):

  • What type of fence system is it – perimeter wire system, wireless?
  • Is the dog fence system built for a specific type of dog – tiny, stubborn, and so on?
  • What is the price range of the dog fence system?
  • Can the fence system order be customized with add ons and changes to the items in the standard kit?

Of The Above Factors – Which Are Most Important In Picking An Electric Dog Fence?

Some of the most important might be:

  • The collar strap fits your dog’s neck
  • The system is designed for your dog’s size (weight)
  • You can put the number of dogs on the system that you need to
  • The system can contain the area of land you need it to
  • The system fits within your budget
  • The system has the settings you need – especially settings like stimulation, beep and vibration
  • The system can be installed above or below ground to your preference and in the configuration you want


How Much Does An Electric Dog Fence Cost?

Each electric dog fence kit has a different cost.

Different models are also going to cost different amounts depending on their features and inclusions e.g. thicker wire, and more/better features are going to cost more.

At the time of purchase – you can also buy additional items that are going to increase the price e.g. additional wire, additional collar devices, etc.

Some of the basic and add on costs you have to keep in mind with getting an electric dog fence are:

  • The Starter Kit
  • Additional boundary wire
  • Additional collar devices
  • Additional batteries
  • Additional transmitters
  • Additional small items like ground staples and wire splices or connectors
  • A surge protector (may or may not come with the system, and can be optional)
  • A dedicated power outlet for the transmitter (if you don’t already have one – you’ll have to get an electrician to install one)
  • Cost to pay a professional to dig and install fence system for you (optional)
  • If you do DIY – time investment to dig and install, and cost to hire a trench digger if you get one
  • Time investment to train you dog/s


How To Install & Set Up An Electric Dog Fence

Each electric dog fence product is different with it’s requirements.

Read the instructions and operation manual that come with the dog fence system you buy for installation and set up information.

Generally though, installation may look similar to this:

  • Laying the wire out above the ground in the configuration you choose
  • Train your dog/s to use the system with the boundary flags
  • Plugging in the transmitter (you may have to get an electrician in to install a dedicated power connection point in the appropriate location if there is not one already there)
  • Connecting up the transmitter, wire and other fence components
  • Charging batteries (if required, or inserting batteries into the collar/s
  • Putting the receiver collar around your dog’s neck
  • Programming the fence settings, and selecting the modes and levels for the system on the transmitter and collar/s. Make sure no other signals or objects (metal objects in particular) are interfering with the frequency your transmitter is set up to
  • Testing everything is working as it should be – if not, contact the manufacturer for trouble shooting
  • Once you know the system is working properly – bury the wire. You’ll have to dig your trenches for the perimeter, or have a third party dig and bury. Above ground wire can be stapled to the ground or fixed to an existing object or fence
  • Test the system again once the wire is buried or fixed
  • Operate the system
  • Replace batteries and fix wires on the system as required throughout operation
  • [Take note of any safety precaution with the system]


For above ground dog fences …

There’s two ways you can install a wire dog fence above ground:

  1. Layout your boundary wire and secure it down with a landscape/yard staple (1 every 5 feet in traffic areas, and 1 every 10 feet where there will not be traffic. This ensures that nobody trips over the wire, lawnmowers do not catch it, etc.
  2. Attach your boundary wire to an existing physical fence – Either wooden (using staples to secure it) or metal (as long as the metal is galvanized, ie: chain link fence)

Check the instructions though as they might have different information on installation above ground. 


Some other tips or directions that might come with installing an electric dog fence might include:

  • Boundary fence wire should be at least 4 feet away from existing cable lines and metal objects so the signal from the electric fence is not interfered with
  • Fence wire corners should be rounded, and not square
  • You might use a circular saw with masonry blade, use an existing expansion seam, or use a driveway traverse strip to cross a driveway or concrete structure in your yard with wire


How Does An Electric Dog Fence Work (When In Operation)?

They all work differently – refer to the instruction manual or guide for information on exactly how they each work.

Generally though, they may work similar to this:

  • A signal is produced from the Fence Transmitter through the Boundary Wire, and communicates with the Collar.
  • The Boundary Wire is buried or attached to a fixed object (or ground) to enclose the dog’s Boundary Area. You temporarily define the Boundary Area with Boundary Flags for a visual aid in training your dog.
  • Your dog wears a Collar Receiver with Contact Points that touch his/her neck and, once trained, is allowed to roam freely in the Boundary Area.
  • When your dog reaches the Warning Zone (an area further from the , the Collar Receiver gives a warning beep and vibration.
  • If your dog continues into the Stimulation Zone (closer to the boundary wire), a safe stimulation will be delivered through the Contact Points to get his/her attention until he returns to the boundary area. 
  • Different systems have different alert settings i.e. different levels of stimulation/correction, and beep or vibration modes. They will also have operational features that will affect exactly how they function


A wireless dog fence system (without perimeter wire) may work slightly differently:

  • Simply plug in the transmitter and it will emit a constant radio signal with a circular range in all directions that defines the boundaries (instead of the perimeter wire being there). Make sure there are no other signals or metal objects that could interfere with the signal frequency
  • Fit your dog with the collar receiver and turn it on. The transmitter sends a signal to the collar receiver.
  • When the pet strays into the warning zone, the receiver collar will give a warning tone. If they continue past the warning zone, a safe, static correction is delivered through the contact points until they return to the safe pet area.


How To Train A Dog To Use An Electric Dog Fence, & How Long Training Takes

It depends on the dog, and also the system.

Read the instructions and operation manual that come with the dog fence system you buy for dog training information.

Most dog fence systems come with training flag visual aids though that you can use to mark the perimeter, and your dog can see.


What Type Of Wire Is Used For An Electric Dog Fence?

The 4 main types are:

  • 20 gauge (thinnest)
  • 18 gauge
  • 16 gauge
  • 14 gauge (thickest and strongest)
  • Twisted wire is also a type of wire that comes with some fence systems – it is designed to create a neutral section of the perimeter that a dog can cross without the collar device activating

Several 14 gauge electric dog fence systems also come with thicker poly coating on the wire for added durability and strength, and protection from abrasion, UV, extreme temperatures and water.


How Much Wire Do I Need For My Electric Dog Fence?

It depends on the size of the area you want to contain your pet/s in.

A certain amount of wire comes with the starter kit, and that amount of wire can contain a certain acreage.

Each brand should have a simple table that converts wire feet to containment acreage.

eXtreme has one of these tables – so, you can refer to those tables when buying wire lengths.

You may need to buy extra wire for wire breakages, but, can use wire splices and connectors as well.


Which Electric Dog Fence Wire Is The Best?

It depends on your needs.

If you want the strongest, most durable wire that can be installed above as well as below ground, the 14 gauge wire with the 60ML jacket is the best option.

20 gauge wire is the thinnest/least hardest wearing of the wires.

You also want to get a dog fence wire that is compatible with your particular electric dog fence product/system.

Read more in this guide about some of the best available dog fence wires available.


How To Bury The Wire For An Electric Dog Fence 

There should be instructions for this that come with each dog fence product.

But, in general, wire can be buried by DIY, or by a professional (some people choose to get a landscaper to dig, lay and backfill the wire trenches, or, the dog fence manufacturer might have teams that do it too)

Installation by others can be better for people who are time poor, have big areas, have injuries, have extra money, or who don’t have the expertise to dig and back fill themselves.

There’s several ways you or a professional may choose to install the boundary wire below ground:

  • Using a standard yard edger to cut a small trench that you can tuck your wire into and cover back up with dirt
  • Using a trenching machine (will dig trench, lay wire, and cover back up with dirt as you go (can be rented from home building stores)
  • Using a garden hoe or shovel to make your wire trench, lay your wire in, and use your foot to close groove

Before burying the perimeter wire, it’s important to check if there are any hazards or obstructions in the ground like electrical cables/conduits, rocks, other services etc. You can call an organisation in your area to come and identify underground utilities for you and mark them on the ground.

It’s also important to consider the layout you want and that you have enough wire.

You should also test the system is working before you bury it (so you don’t have to undig it in case there is an issue).


How Deep To Bury The Wire

It depends on the fence system – read the installation instructions guide that comes with the fence system.

Some are between 1 to 5 feet deep. Some are deeper.

Some systems allow above ground installation without digging or burying required.


Some Safety Considerations For Using An Electric Dog Fence

Safety is extremely important with an dog fence.

Always always get your vet’s advice or the advice of an animal health and/or training expert – nothing is a substitute for professional advice.

Some general safety guidelines for using a dog fence humanely might be:

  • Buy from a reputable company who put proper use of the dog fence and the safety of the dog as a priority 
  • Read and follow the operating guide, instruction/safety manual and training guide that comes with the dog fence system from the manufacturer for operation and safety instructions and guidelines
  • Pay attention to any warnings issued by the manufacturer
  • Monitor your dog’s response both mentally and physically to using a dog fence. Take the collar off immediately and discontinue use of the system if you notice any negative implications or reactions

A good dog fence that uses static stimulation should simply stimulate the muscle (to the point of reflex) to get the dog’s attention, but should not cause pain (it might be slightly annoying for the dog to act as a small deterrent – but shouldn’t cause pain or harm). It certainly shouldn’t cause a ‘sharp pain’ to the muscle or body. 

To get a safe stimulation level – you can always start from the lowest stimulation level, and work your way up to a level that gets the dog’s attention (such as changing body language when a stimulation, vibration or tone is administered) without any visible sign of pain or harm (such as yelping, or showing signs of stress).

A good dog fence company should give you all the necessary safety, use and training instructions, and should have a dedicated customer service line to help when you being using the fence system.

The static function does not need to be used either – tone and vibrate training modes can be used instead.

Some owners like to use their dog fence system as a temporary training tool i.e. once their dog/s have learnt the boundaries and are properly training to stay in the yard, they turn the fence off or remove it.

If the dog starts going outside the boundaries again, they use the fence again to re-train their dog.

As a safety precaution for humans as well – make sure to get a qualified company to do an underground utility search and get these utilities marked before doing any digging.
