Are All Wireless Dog Fences Circular? – YES (And Here’s Why)

Many owners understand that certain electric dog fencing systems have specific configurations and are great alternatives to physical fences.

But are all wireless dog fences circular or can you change the shape to suit your yard?

Wireless dog fence boundaries are always circular upon installation around the fence transmitter’s location. The size can be changed, but the shape cannot.

This transmitter connects to a correction collar and works to enforce a dog’s safe zone while training them to respect boundaries.

Wireless fences can only have a circular boundary.

Wireless dog fences will form a circular boundary around the location of the fence transmitter.

Unfortunately, this may pose an issue to someone with odd property lines or a residence in a crowded neighborhood. 

However, wireless dog fences can convert a varied range of property into an enclosed circular barrier.

Most wireless fencing systems will allow the owner to adjust the boundary lines as desired, as long as the overall shape remains circular.

Wireless fencing systems are also portable.

These portable wireless dog fences are beneficial resources for owners who travel and make a great dog fence for camping.

They’re also compact to promote trouble-free transportation.

If your property can fit a smaller circular boundary, we recommend researching a system that allows boundary line adjustments.

Can You Change the Shape of a Wireless Dog Fence?

Can You Change the Shape of a Wireless Dog Fence
These systems are simple to install and inexpensive. You cannot, however, change the size or shape of the containment area.

Wireless dog fence boundary lines will always form a circular perimeter around the transmitter.

You can adjust the range of the circle to an extent, but the shape will remain unchanged. 

If you think in-ground fencing is the best option for you, keep in mind that the installation requires a trench dug around the yard’s perimeter. 

Invisible Fence is a company largely trusted and recommended by pet parents and they will provide professional electric dog fence installers to install in your desired area.

Invisible Fence also offers free consultations for installation and professional dog training services available on the company website

What is the Radius of a Wireless Dog Fence?

What is the Radius of a Wireless Dog Fence
You can change the boundaries from a few feet to 180 feet (approximately 1/2 acre).

The range of wireless dog fence systems covers a scope of property distances, but they can generally cover 100ft or more.

Additionally, some system transmitters can sync to another transmitter that can extend the boundary range.

Stop by our related article on Invisible Fence Expanding for more on how to broaden your fence boundaries.

If you need a large amount of property enclosed, wireless dog fences may not be the best option.

In that case, GPS dog fencing and tracking systems will generally be able to cover extended ranges of property.

What Interferes with a Wireless Dog Fence System?

What Interferes with a Wireless Dog Fence System
Refrigerators, stoves, and large metal cabinets can all interfere with the wireless signal, resulting in unstable boundaries and an unreliable perimeter. This can cause your dog to be corrected unnecessarily.

Wireless dog fencing systems have a transmitter that connects to the correction collar worn by a dog.

Therefore, the transmitter must be placed on the first level of a structure protected from harsh weather. 

Owners will need to keep the transmitter away from metal objects like refrigerators, metal cabinets, and metal roofing

Will a Neighbors Wireless Dog Fence Interfere with Another System?

Even if the Pet Fences are from the same manufacturer and model, they can cause conflict.

Urban and suburban areas are popular spots for families and dog owners, so the chance of having a neighbor with a wireless fence can be high.

Unfortunately, if you have a neighbor with a system, it can interfere with yours, and cause malfunctions.

We recommend speaking with neighboring dog owners to determine if any wireless dog fence systems are in the range of your property that may cause fence interference

Can You Use a Wireless Dog Fence on a Hill?

Can You Use a Wireless Dog Fence on a Hill
The hard wireless dog fence in a custom shape will accommodate sloping hills and contours.

When researching and planning for your wireless fence installation, you want to verify that your property has the best environment for efficacy.

Hilly areas with dense trees or shrubbery can interfere with a wireless fence system. 

Hills and large trees may threaten a wireless fence system’s proper functionality because they can interfere with how the transmitter can read its surroundings.

These obstacles can interfere with how the transmitter communicates with the correction collar. 

If the transmitter cannot successfully connect to the correction collar, it may begin to exhibit signs of malfunctioning.

If the collar starts to beep or correct your dog when it’s not needed, take it off immediately and attempt to solve the issue. 

However, dense trees and hills will not always interfere with a wireless fencing system.

Several wireless systems are more compatible with this environment than others, here is an article on the Best Fence for Sloped Yard

Do Wireless Dog Fences Interfere With WIFI?

Do Wireless Dog Fences Interfere With WIFI
Given that most WiFi signals occur between 2.4 and 5GHz frequencies, you should have no problems because wireless fencing operates below 9kHz and is well within the FCC’s rules.

Can Invisible Fence interfere with WIFI?

Wireless dog fence systems should not interfere with any WIFI connections as they run at differing frequencies than WIFI and are not at risk of any interference from each other.

Additionally, wireless dog fences do not require a connection to the Internet or WIFI.

As long as the transmitter is connected to a reliable electrical outlet, and kept away from metal objects and harsh weather conditions, you should not encounter system issues.

To maintain safe function, the correction collar must stay adequately charged with the batteries changed regularly.

We also recommend regular cleaning of the connection points to avoid any issues due to debris build-up. 

If you would like to learn more about the cleaning and general upkeep of a correction collar, here is a great article that discusses helpful tips.


We have sadly reached the end of our article discussing topics related to wireless fence systems, installation, interferences, and alternative containment options.

We hope you found this article beneficial and wish you and your canine companion the best of luck!
