Underground dog fences: Basics

Underground fences for dogs are simple devices which consist of a receiver, located in a collar and an in-ground line. Each time a dog reaches the fence or pass it, the collar will vibrate or shock him. As such, he will learn to stay in invisible boundaries all the time, without you having to construct an actual fence.

There are wireless models as well. They have a transmitter located in the house, so they create round area all around your property. The range of these devices varies between 22 and 150 feet.

Benefits of underground dog fences are countless. Your dog will be safe at all times simply because he will stay where you want him to be. At the same time, he won’t escape nor go out on a road himself. All of this means that he will live in a much safer environment. Obviously, your home will look precisely as you want it and there won’t be any, visible fence. Another advantage is the fact dogs cannot jump over or go under these fences, therefore they are highly rated as the safest of them all.

Factors to consider when looking for best underground dog fence

If you are looking for the best electric fence for your dog, you will have to take into account several factors. They can ensure your fence is perfect for your requirement and always works perfectly. So, let’s check out those factors.

  1. Covered area

Covered area simply means the size of the invisible area which will be a boundary to your pet. Some models have up to 50 acres of supported range, which is superb. Others may have lower than that. Keep in mind that these fences allow you to create an area of an irregular shape, where your dog will be free to spend time.

  1. Type of correction

Some models have only beep warnings, while others come with shock correction, which is far more reliable and safer. It is best to have all of them, due to the fact dogs will realize that they must obey the boundaries, therefore they won’t need a shock correction. In addition, pay attention to the warning which will appear once a dog reaches the boundary.

  1. Waterproof or not

Most models are waterproof, but not all are! This is an important factor to consider and it refers to the collar specifically. A dog will get wet eventually, so you don’t want his collar to stop working. Different models are rated differently for waterproof feature.

  1. The size of a collar

How big or better said what the diameter of a collar is. Bigger ones are developed for larger dogs, while smaller ones are ideal for small and medium-sized pets. This factor depends solely on your dog and his size.

  1. Battery

One of the most important advantages of these fences is the fact they can be plugged in into the power grid and they will stay activated all the time. This is the main advantage compared to any other type. But, a battery in the collar must be recharged or replaced. Look for a long running time. You can get up to 10 days.

  1. Hair of a dog

How long a hair of your dog is can affect the success rate of keeping a dog under control and within the pre-set area. The main reason is the length of contact points. Longer hair requires longer prongs, while short-haired dogs require shorter ones.

Advantages of invisible dog fences

An in-ground pet fence is capable of offering several advantages. The first and the most important one is the fact it can be used for irregular space. Any shape is possible because you will literally set up the fence as you like. The second main advantage is in the price, compared to traditional fences. These ones are far more affordable. Wireless models are limited to a circular shape, which isn’t always desirable.

The customizable area is important as well. In essence, you can make the fence go all around your garden, therefore you can protect it. The same goes for paths and drive-by. There is no interference either, which is common among wireless fences. They are also known to cause boundary wobble, which will have a negative effect on the stability of the entire system. In addition, wireless models are not great for larger dogs, who are stubborn. Those dogs will require additional corrections.

All of these fences are expandable, meaning that you can increase the area in which your dog can move freely. Then we have the fact you don’t need any permit to use the underground pet fence, while physical one may require this addition.


There are a few drawbacks here. First of which is the dog size. All of these fences require the minimal size of a dog of 5-8 pounds. Also, only dogs older than 6 months can use these collars. This means that most, smaller and young dogs are unable to be secured with this fence.

When it comes to setting up the fence, it is more complicated than the wireless model, for example. You will have to dig-in all around your home, to set the limiter wire. After that, you will have to adjust it and only then you can use it. This requires plenty of time.

The last, but not least, you won’t be able to travel with these fences because they are permanently implemented into your backyard. But, this is a well-known fact and all dog owners are considering in-ground fences as a replacement for traditional fences.
