II. About Underground Dog Fence

An underground dog fence is an electronic fence that will train your dog not wander outside of the boundary that you set. They cost a fraction of what a physical fence would cost and they are very effective.


To install an underground dog fence, you bury an electric cord around the perimeter of your yard in a shallow trench and you install flags as a visual reminder for your pet of where the boundary is located. The cord is connected to a transmitter, which is usually housed in the home, a garage or a garden shed.

The best underground dog fence kits will also include at least one special dog collar. When your dog approaches the boundary, the collar will emit a tone to warn your dog not to go any further. If your pet continues towards the boundary, the collar will emit a mild electric shock that will startle your pet and discourage it from crossing the boundary.

III. Warning: Underground Dog Fences and Wireless Fences Are Not the Same Thing

Unfortunately, some less than well informed websites make the mistake of assuming that wireless invisible dog fences and in-ground dog fences are the same thing, but they are two distinctly different types of invisible dog fences, so be sure that you understand the difference between the two before you buy a dog fence.


In Ground Dog Fence Boundary Zone


Wireless Dog Fence Boundary Zone

A wireless dog fence uses a radio signal to define the boundary. That makes them easier to install and it means that you can easily take the system with you when you move home or you go on vacation, but wireless systems will only be able to create a circular boundary, they can be prone to boundary fluctuations, and they may not work on uneven or sloping ground.

An underground dog fence system uses a wire that is buried in a shallow trench in the ground to define the boundary. Some models do allow for the wire to be laid above ground as well. Underground dog fence systems take longer to install, because you have to dig a trench to lay the wire in, but they are far less prone to boundary fluctuations, they can cover irregular shaped boundaries, and they can be used on uneven or inclining ground. You can also create safe zones with an underground dog fence system, which allows you to create areas of the boundary that the dog can pass safely through without receiving a correction. It allows you to fence off areas within the boundary, such as pools, ponds or flower beds.

Overall, wireless dog fences are easier to set up and they are portable, but they have their limitations and they are generally less reliable than underground electric dog fences. If you are looking to create a permanent electric dog fence around your property, your best option would probably be to purchase an underground, wired, invisible dog fence.

V. How To Install An Invisible Fence

VI. Advantages and Disadvantages of In-ground Dog Fences

While in-ground dog fences do require more effort to install than a wireless dog fence system, they do have some distinct advantages.

The main advantage is that an underground dog fence is a lot more flexible than a wireless system. A wireless dog fence creates an invisible boundary around the transmitter that is circular, which means that they are not as effective in an irregular shaped field or yard as an in-ground system would be. When you use in-ground dog fences, however, you can bury the cord in whatever shape you like. The best underground dog fence will also allow you to create safe passage areas where your dog is allowed to pass through the boundary.

Another aspect where wireless fences can fall short is in areas of uneven ground. If your yard has a slope on it, that can interfere with the radio signal from a wireless dog fence, whereas an in-ground fence wouldn’t have that problem at all.

On the plus side for wireless systems; they are portable. Because there is no buried wire, you can easily take a wireless system with you when you move home, or you can take it with you on vacation.

Here’s a summary of the main advantages and disadvantages of an in-ground dog fence.


  • The boundary can be any shape
  • Entry and exit points can be built into the boundary
  • Larger areas can be covered
  • Areas within the boundary can also be covered, such as a pool or flower beds
  • Uneven ground will not interrupt the signal


  • A wire has to be buried in a trench in the ground
  • Takes longer to install than a wireless system
  • Not as portable as a wireless system
  • Once the cord has been buried, the boundary is fixed

VII. Electric Dog Fence Wire for Your Underground Dog Fence


Underground invisible dog fences come with a reasonable amount of electric cord for burying around the perimeter of your yard, but there are times when you might need to some more wire. When that does happen, it is usually advisable to purchase the suppliers’ own brand of cord to go with the dog fence that has. Here, we discuss why you might need to buy extra dog fence wire and we explain which wires you will need to buy for the leading underground dog fences.

1. Some cases where you might need to use more dog fence wire

Most in-ground invisible dog fences come with sufficient wire for an average sized yard, along with a good number of training flags, but there are a number of reasons why you might need to purchase additional wire for your dog fence system:

1.1. You have a very large boundary

One of the advantages of an in-ground dog fence over a wireless system is that it can be expanded to cover a wider area simply by purchasing more dog fence wire. If this is the reason that you need purchase more wire, read the product manual first and find out what the maximum area is that your unit will cover.

1.2. You are moving home

One of the disadvantages of a buried wire dog fence is that they are not as easily portable as a wireless dog fence would be. However, if you buy some additional dog fence wire for your in-ground dog fence when you move home, all you need to take with you is the transmitter and the dog collars.

1.3. You want to change the shape of your boundary

With an underground dog fence system, you can create an irregular boundary and, using twisted wire, you can create safe areas over which dogs can pass without being given a correction. If you change the layout of your yard, you get a pool, or you enlarge your house, extra dog then you might need to purchase more electric dog fence wire to accommodate those changes to the boundary

1.4.You want to set up a temporary boundary

If you are going on a long vacation, you might want to take your underground dog fence with you and set up a temporary boundary for your dog where you are staying. If you extra dog fence wire, you can take the main transmitter unit and the dog collars with you on vacation and set up a temporary boundary for your pet.

2. Important features need to check before buying underground dog fence wires

By far the easiest way to make sure that you have the correct wire for your underground dog fence is to use the wire that is recommended by the manufacturer, but you can use other wire with your dog fence if you really want to.

2.1. Thick gauge or thin gauge wire?

Some people like to buy thicker gauge wire than that which is supplied with their in-ground dog fence system because it is less prone breakage. In some cases, a thicker gauge wire will give you a greater range was well, which can be useful if you have a very large boundary to cover.


The downside to a thicker gauge wire is that it is harder to work with because it is not as easy to manipulate as the thin gauge dog fence wire is. You will also find that thick gauge wire is quite a lot more expensive, so that’s another thing to bear in mind.

2.2. Twisted wire or untwisted?

The difference between twisted wire and untwisted wire is very important indeed. Untwisted wire is used for the parts of the boundary that you do not want your dog to cross over and the twisted dog fence wire is used for the safe areas of the boundary that your dog is allowed to cross.

2.3. Colour can make a difference

Of course, the colour of the dog fence wire makes no difference at all to its performance, but the colour can be important to some people. If you intend to use your extra wire to set up a temporary boundary on the surface of the ground, a bright colour will make it easier to see. If you do this, don’t forget to take some flags with you as well, because your dog will not be familiar with where the boundary is.

2.4. How to work out how much dog fence wire you will need

The easiest way to work out what length of dog fence wire you will need is to walk around the boundary and count your steps. If you multiply your steps by three, you will have a good approximation, in feet, of the length of wire that you will need.

The basic system comes with enough wire and flags to cover an area of 1/3 of an acre, but with additional dog fence wire and flags, it can cover an amazing 25 acres.

This will cover an additional 1/3 of an acre, but it doesn’t include extra boundary flags, so you will need to purchase those separately.

3. PetSafe Stubborn Dog In-Ground Fence - Wires

IX. Benefits of Underground Dog Fence

If you have a dog or dogs that you want to give the freedom of your garden or yard, but you don’t want them to wander off your land, then you have three options. You could build a fence or a wall around your property, but that is very expensive and you might not want to close yourself in, or you can buy an electric invisible dog fence.

Invisible dog fences come in two main types; in-ground wired fences and wireless dog fences. Wireless dog fences are much easier to install and they are more portable than in-ground dog fences, but they will only create a circular boundary and they are prone to boundary fluctuations.

Here are the main benefits of wired invisible dog fences.

1. Much cheaper than a physical fence

Underground dog fences are many times cheaper than a physical fence and, if you have a beautiful view to look out on from your garden, they won’t restrict your view. A typical underground dog fence will cost you, at most, a few hundred dollars, whereas a physical fence could cost you thousands of dollars.

2. They will cover irregular boundaries

A wireless dog fence will create a circular boundary around the transmitter, but with a wired underground dog fence, the boundary is created by where you place the wires, so it will cover irregular shaped boundaries as well.

3. You can create safe zones with an in-ground dog fence

If you twist the two wires of an in-ground dog fence together, it will create a safe zone through which your dog can pass without receiving a correction. That means that you can leave a safe passage for your dog to enter and exit your home and you can also fence off areas within the boundary, such as pools or ponds.

4. Inclines are no problem

If your yard or garden is on an incline, or the ground is uneven, then you might find that a wireless dog fence doesn’t work. Because an underground dog fence doesn’t rely on a wireless signal to create the boundary, it can be used on uneven ground and on steep inclines.

5. No Boundary fluctuations

One of the biggest issues that people have with wireless dog fences is that the boundary can fluctuate, which can be very confusing for a dog. While wireless dog fences do have their advantages, underground dog fences do not have this particular issue. Any fluctuations in the boundary of an in-ground wired dog fence, which might be caused by variations in the performance of the receiver in the collar, will be minor compared to those that can occur with a wireless dog fence.

6. Peace of mind

Once an underground invisible dog fence has been installed and the dog has been trained, an owner can sit back with the peace of mind that the dog won’t stray from their property. In-ground dog fences are extremely effective and reliable and they are a much more economical solution than a physical fence. A dog that can run loose can be a nuisance and a danger to people, and it can also be a danger to itself. An underground invisible dog fence provides a secure boundary through which a well-trained dog will not pass. It’s the most economical, reliable, and safe way to keep a dog within the boundaries that you set it.

X. Conclusion

In summary, the best in-ground dog fence systems will provide an effective and humane means of keeping a pet with a given boundary. The main downsides to buried cord dog fences are that you have to dig a trench around your yard and they are not as portable.

Both in ground systems and wireless systems work well and when combined with proper training, they will teach your dog to stay within the boundaries you set it.

If you don’t mind that little bit of extra effort, the best underground dog fence systems are generally more reliable and flexible than wireless systems and they can cover larger areas which, for many people, will outweigh the disadvantages that they may have.
