Wireless Dog Fence 101: How Does it Work?

A wireless dog fence may be the perfect solution to keep your pets safe while they explore. You can give them plenty of freedom while they’re playing outside.

Invisible fences have several advantages over other fencing options. They are easy and convenient to install, which wired fences cannot offer.

You won’t need shovels and wire after installing a wireless dog fence. You plug it in, turn it on and place the transmitter unit anywhere inside your home. The dog fence is also portable so that if you ever need to move or travel for any reason, you’ll be able to take it with you.

How do wireless dog fences work?

Wireless fencing systems are made up of two components, the transmitter, and receiver. We will discuss the mechanism, method to create a safe area, and the training process.

A transmitter

The transmitter can be placed somewhere out of the way, like a closet or utility room. When you turn the transmitter on and plug it in, it starts sending signals to your dog’s collar so they can be tracked.

Wireless dog fence transmitters can be adjusted to create an area with a circumference of 15ft-90ft. The signal is detectable in this circular zone.

A receiver

The receiver collar is scanning for the transmitter signal at all times. This signal can be located as long as your dog stays within the designated area.


If your dog tries to move past the boundary area of a wireless fence, he or she will be warned with an audible signal. If the dog continues moving, the collar will eventually lose contact with it. Once this happens, your dog will feel a slight sensation.

This way, a barrier is created that your dog can stay in and become accustomed to. The area around the barrier is completely safe for dogs so that they can go into the corners of their space without fear.

Creating safe area

Although it is recommended that you use a single transmitter unit for your dog, this isn’t the only way. If you want to create a more accommodating area for your animal, combining units should work just fine.

The training process

  • To start the training process, you need to decide how many transmitter units you need and locate them in the appropriate areas. The dog will likely require initial training and should be taught to recognize the boundaries.
  • Mark the “safe area” with visible flags to show your dog the boundaries. These flags will let your dog know where he can and cannot enter.
  • Dogs usually won’t cross a boundary unless motivated to do so. You can train your dog is to walk him around the parameter on a leash so he gets used to the area. After some days, your dog will likely know where its limits are.
  • You can now turn the unit on to the lowest power setting. Let your dog experience periodic warning signals and corrections as he or she walks around the perimeter.
  • In a few days, your dog will stop when you turn on the audible signal. Once he does, removing the flags is perfectly safe because the training is now complete. You can also revert to using normal power settings for the transmitter if you wish.

Things to consider before installing a wireless dog fence

Here are some key considerations if you are going to install a dog fence:

  • Wireless dog fences are not suitable for small properties. The property needs to be at least 30ft wide.
  • A wireless dog fence might not work well if your garden is sloping or terraced.
  • Trees and other wooded areas can interrupt signals. Large metal structures and fencing can impede the signal, leading to dead spots in areas affected by these.
  • A wireless dog fence collar shouldn’t be worn indoors as other objects can activate it. TVs, dimmer switches, and household appliances are all known to produce signals triggering the receiver.
  • The boundaries of wireless dog fences fluctuate all the time, which means the boundary changes, leading to confusion and danger to your dog. Some systems can have a wobble of 16ft.
  • A wireless fence cannot be used in connection with a house that has a mobile phone signal booster or smart meter.
  • The Wireless dog fence receiver collar is big and heavier than most other collars, so it’s usually best suited for larger breeds like Labradors or German Shepherds.
