How a Dog Fence Works

So you are thinking of getting an electric dog fence? An underground dog fence is an excellent choice for containing your dog. Let’s take a moment to talk about how an invisible dog fence works and why it is such a great solution for keeping your dog at home with you, where he or she belongs.

First, let’s establish that an underground fence, versus a wireless electric dog fence is a much better choice. Although wireless is effortless to install, there are many variables that can cause a wireless fence to fail. If you want the most dependable, customizable, best invisible dog fence available, read on to learn about how our American-manufactured eXtreme Dog Fence® works.

Components of an Inground Dog Fence

There are 3 crucial components of a pet containment system. These include dog fence wire, a dog fence transmitter, and a special receiver collar that your dog wears. The transmitter, located inside of your home, is the brains of the operation. It transmits a radio signal throughout your dog fence wire. Along with our manual our extreme videos help you learn how to program your transmitter with ease.

Your dog fence wire, which is buried around your property, creates a border that you have designed yourself. Although your border is customizable, you must always establish a complete loop back to your transmitter in order for the fence to work.

Your dog wears an invisible fence collar, which triggers when he approaches a predetermined distance in front of your dog fence wire. Your dog’s receiver collar is powered by Perimeter 6-volt Extreme invisible fence batteries.

Dog Fence Correction

The concept of static correction is the same as is used in dog behavior training. Here is what it feels like to your dog. Run across the carpet in your socks and then touch a doorknob. That is a static shock, which is similar to what the dog feels when he receives a static correction. With the eXtreme Dog Fence® there are 7 different levels of correction to choose from, in addition to a beep-only mode used for training.

A Word About Dog Fence Wire

There are many different gauges of wire available for your pet fence. You will find 20 gauge wire, 18 gauge, 16 gauge wire, and 14 gauge. With so many options, how does one know which wire to choose? Here is some advice from the experts.

Though 20 and 18 gauge wire is inexpensive, it is not an ideal choice. This is because it is thin and very vulnerable to breakage or wearing down over time. A cheap dog fence comes with this type of thin dog fence wire. Logically, you may be focused on finding a fence for sale at a low price point, but keep in mind that you get what you pay for.

16 gauge wire is a step in the right direction, but still not the best selection.

The best electric dog fence comes with 14 gauge dog fence wire. If you want your dog fence wire to last a long time, 14 gauge wire is the way to go, without a doubt. Our 14 gauge wire is designed to last a lifetime. It will not degrade, or break unless a blade is taken to it. In addition to this, the performance of your electric dog fence will be enhanced by its superior signal conductivity.

In fact, our 14 gauge dog fence wire is so durable that you don’t even need to bury it if you don’t want to. You can simply use fence staples to tack it to the top of the ground.
