Are your neighbors often complaining about your dog destroying their yard?

As the name goes, this type of fence is invisible and doesn’t spoil the look of your house. It is specially designed for pets like cats and dogs.

If you don’t want your dog to cross the boundary and destroy your neighbor’s yard, this fence system will help them to keep them in your area. It is convenient, reliable, and reasonable, and offers complete protection.

If you have a backyard that is not completely fenced in, installing an invisible electric fence might be the solution. It is an invisible fence that helps you to keep your pet dog inside the perimeter. 

This type of fencing system has three important elements, i.e., underground wire, transmitter, and pet collar. The transmitter is the main device that sends radio signals to the fence and dog’s collar.

You can place the transmitter wherever you want, like around garden beds, fountains, and other decorative areas. Moreover, an invisible electric system does not have to be installed in a central location.

Wired dog fences are entirely invisible, and unlike traditional physical fences, you can install them anywhere. You have to use the underground wire and bury it in the ground. 

It is important to have a detailed map of your property so that you can properly gauge where the wires will need to be placed. Once you mark the perimeter around your house, install the wires. 

These fences work by allowing you to place a battery-operated collar in the dog’s reach. The collar will detect a signal from the transmitter and send a static correction signal to the dog. It will prevent them from crossing the boundary.

The strength of the signal depends on the size of your dog, and you must make sure that the fence is placed in the right area to keep your dog out.

You need to train your dog to respect the boundaries. There are flags available which you can use to mark the boundary and teach the dog how to avoid moving out of the boundary.

What Is Underground Dog Fence Wire?

If you’re thinking about installing an underground dog fence, you’ll need to know what is involved in doing so. You’ll want to choose a dog electric fence wire that’s strong, long-lasting, and easy to install. 

Underground fence wire is one of the most important components of the invisible fence system. You have to mark the boundary outside the house and install the wire underneath.

The wire works as an invisible boundary that your dog cannot cross. The wire sends a signal to the transmitter when the dog is near to prevent the dog from crossing the boundary.

You can keep the wire on top, but it is best to bury it 2 or 3 inches under the ground for a longer lifespan. This way, it will be safe from water, wind, and dust. 

Before installing an underground dog fence, you’ll want to choose the right wire gauge for your property. While a higher-gauge wire is ideal for a small backyard, a smaller-gauge wire will last longer. 

Additionally, the wire should be coated with polyethylene to protect it from the elements. If the wire wears out prematurely, the signal strength will decrease. Therefore, it’s best to choose a durable wire for your dog’s fence.

Once you’ve made your decision to use an underground dog fence, you should decide on the wire. A smaller gauge wire is more durable and will last longer. It’s best to use polyethylene-coated wire to protect it from the elements. 

When burying underground dog fence wire, you’ll want to use a professional-grade wire with a durable coating to withstand water exposure and general wear. This way, you’ll be less likely to have to replace it prematurely. 

You’ll want to make sure that the wire is sturdy and resistant to corrosion. Before burying the wire, you’ll need to determine the exact location where you want the fence. It should be buried at a depth of three to 2 to 3 inches. Once the wire is buried, it’s a good idea to place marker flags along its perimeter. 

It will help you to easily find and remove the wire. Burying the wire is important to avoid tripping. Make sure you use a strong and sturdy wire to last longer and keep your dog inside the yard.

How to Choose the Best Wire for Underground Dog Fence?

Underground dog fences have become very popular among pet owners. It is one of the best ways to prevent dogs from wandering around and give them the freedom to run and play within the yard. However, to ensure that the fence system works properly, you need to choose the best wire for underground dog fence. Here are some factors you need to consider to make the right choice. 

  • Wire Gauge: 

When choosing the wire for your underground dog fence, consider its gauge. Thinner wires have more resistance to breakage, and a thicker gauge is more efficient for keeping pets within boundaries. Dog fence wire is available in 20-gauge, 18-gauge, 16-gauge, and 14-gauge. 20-gauge is the thinnest whereas, 14-gauge is the thickest. Make sure you have the perfect wire gauge. 

  • Durability:

The wire for an underground dog fence must be durable. The higher the gauge, the better. A lower gauge will give more durability to the fence. If the wire is buried underground, it should have a coating of polyethylene, which will protect it from water. The signal strength will decrease over time as the wire gets buried. Purchasing a more durable wire will ensure your fence system lasts longer.

  • Wire Resistance:

You need to consider wire resistance as well. The wire should be strong and resistant to temperature changes. It should also be resistant to stress and cracking. It is better to choose a wire with improved wear resistance.  

  • Signal Transmission:

Choose a wire with perfect signal strength. The wire should be able to easily transmit the signal so that your dog can get a proper correction message. Make sure the signal strength is not low, or else your dog can easily cross the boundary. There should be no hindrance in signal transmission.

  • Workability:

Another thing you need to consider is the workability or flexibility of the wire. It should be flexible and easy enough to work with. This way, you can easily twist the wire and customize the configuration. Thinner wires are more flexible and easy to install. 

  • Wire Type:

You need to consider the type of wire as well. There are two most common types of wires available, i.e., manufacturer grade and professional grade. The professional-grade wire is designed to withstand harsh environmental conditions, water exposure, and general wear. It can help you avoid premature digging up of your underground dog fence. The manufacturer-grade wire is mostly available with dog fence kits. These are lightweight medium-quality wires. 

  • Budget:

Make sure you consider the cost of the wires as well. It will help you to compare different types of wires and choose the best one. Check the size, length as well as features along with cost. 

Frequently Asked Questions

1. What gauge wire is best for dog fences?

You can use 20, 18, 16, or 14 gauge wire for dog fences. 20 gauge is thinnest, and 14 gauge is thickest. If your yard is small, go with 20 or 18 gauge. However, if it is large, 16 or 14 gauge is best for you. The heavy-duty wire is ideal for above-ground installations, as it is more durable and stands up to harsh weather. If you are planning to install the dog fence above-ground, you may want to consider heavy-duty wire as it offers added durability.

2. How deep do you bury wire for dog fence?

You need to dig a trench of 3 to 24 inches to bury wire for the dog fence. Avoid burying the wire deeper than the maximum depth because you could alter the signal strength and run into buried utilities. It is best to bury the wire 3 inches underneath the ground for maximum signal strength as well as protection against weather and outdoor hazards. 

3. What kind of wire is used for an underground dog fence?

When it comes to an underground dog fence, the wire you use is very important. It must be solid and heavy-duty so that it can withstand the elements and the wear and tear that it undergoes from water exposure. It is a solid insulated polyethylene wire. This is the best wire for outdoor use and can handle the constant pressure that the dog’s movements place on it. It is best to buy one made of heavy-duty 14-gauge wire. This wire will withstand time, and you can install it yourself without the help of a professional.

4. Do underground dog fences really work?

Yes, these fences really work if installed correctly. Unlike regular fences, which can be inconvenient and expensive, underground dog fences are easy to install and maintain. They work by sending a correction message to a dog when it approaches a no-go area. Because these devices can be easily hidden in the ground, they are an ideal way to contain a puppy.

5. What type of wire does PetSafe use?

There are two types of wire that PetSafe recommends for its fence systems. The first type is called standard, which is used in most installations. This wire is made from 20 gauge copper PE, and the second is called heavy-duty16 gauge wire. The wire should be thick enough to withstand rough use. Both wires are compatible with in-ground pet fence kits.

Bottom Line

Underground dog fence wire is the core component of the invisible fence system. It helps you to keep the dog inside the yard without installing a traditional fence. All you need to do is buy fence wire and bury it underneath the ground. However, you need to choose the best wire for long-lasting use and perfect signal transmission.
