No matter how trained and disciplined your dog is, there’s always a risk that he will hear or see something that will make him run off.

When pet owners think about keeping their dog from escaping, the first thing that comes to mind is a physical fence. But unless you want to keep other animals out, this isn’t really necessary, as most electric fences are far more flexible, less expensive, and don’t require special permits.

If you don’t mind the do-it-yourself factor, you can have an in-ground fence in your backyard within a couple of days. Alternatively, a wireless fence only takes a few hours to set up and is ideal for people who tend to move a lot.

Navigating through the different products, however, can be confusing, especially if you don’t understand all of the technical mumbo-jumbo.

Below are the best invisible dog fences, whether you’re looking for an in-ground or wireless fence. I’ll also talk about what you should look for in an invisible fence, how these kinds of fences work, and how they can be used to train your dog effectively.

In-Ground vs Wireless Dog Fence

There are two types of invisible dog fences – in-ground and wireless. But in order to know which one is best for your dog, you have to be familiar with the main differences between the systems:

In-Ground Dog Fence

Every basic in-ground fence system should come with these parts:

  • Fence Transmitter
  • Boundary wire
  • Receiver collar
  • Training flags (optional)

The fence transmitter job is to send a radio signal through the boundary wire, acting as an antenna that carries the message to the receiver collar on your dog. So instead of warning your dog when he gets too far from the transmitter, this fence uses a wire that’s usually hidden underground.

Once your dog gets close to it, the collar gives your dog a correction to let him know that this is where the line is. For example, it produces a warning tone when your dog starts to get too close to one of the edges of the perimeter you set. If he attempts to cross it, the collar will send a low-grade pulse to prevent your him from leaving the yard.

This type of fence is suitable for homeowners who want their dog to stay within the limits of their yard. The installation takes a bit of time and patience, but you’ll save money by doing it alone and you can even make this a fun family activity. You’re also not limited to the radius of the wireless transmitter and you can set your own boundaries.

Wireless Dog Fence

The great thing about a wireless fence system is its portability. Whether you’re a renter or planning on buying a house, this system saves you the hassle of laying an in-ground fence that you’ll just have to take out shortly after. It’s also ideal for taking on trips and vacations since you can set it up and have your dog off leash without worrying that he will wander too far.

A wireless dog fence kit includes a transmitter and a collar. The transmitter sets the radius that your dog is allowed to be in and once he moves too far away from the transmitter, the collar receives a static correction that helps your dog learn to recognize the boundaries you set for him. The maximum wireless boundary will vary depending on the product.

What to Look For in a Dog Fence?

Coverage Area

The coverage area of an invisible fence depends on the wireless radius or the length of the wire, so the more boundary wire you have, the more space you can protect. Some fences offer only 1/2 acre, while others can cover up to 100 acres. Keep in mind that most in-ground fences can be extended, while wireless fences are somewhat limited.

Before choosing a dog fence, you need to decide on the area you want to cover. Perhaps even draw the desired perimeter on paper first, then pick the one that meets your needs. In the case of an in-ground system, you can always buy additional wire in case you’ll ever want to increase the scope of the fence.

Easy Installation

Obviously, a wireless dog fence is the simplest solution. As the name implies, for an in-ground fence to be invisible, you’ll have to hide the wire in the ground. The payoff is that there’s no limit to its flexibility since you can design the boundaries yourself.

If you know your way around the garden and you’re willing to put in the time and effort, installing an underground fence can be very rewarding. However, keep in mind that some systems can be harder to set up than others.

As a rule of thumb, you should always lay the boundary wire over ground and attach the transmitter to a wall inside an interior location or near an outdoor outlet that’s protected from the weather. Then, connect the wire to the transmitter and test it using the receiver collar.

Once everything is working, you’ll need to bury the wire to create an invisible fence. Use a spade to make a slit one to three inches deep and lay the wire inside it. Now all you’ve left to do is just place the flags and start training your dog.

Collar Features

Most of the receiver collars come with 4 to 5 correction levels, as well as a tone-only mode. The more correction levels available to you means you can find the best stimulation for your dog’s size and tolerability. Obviously, a toy dog and a large breed dog shouldn’t have the same correction level.

A tone-only mode gives your dog a warning instead of using a shock right away. That way, you can also train him in case you don’t want to use the static feature for some reason and it may be enough for some dogs.

The collar should also be protected against water since your dog will probably get wet at some point and you don’t want the collar to get ruined because of that. You also need to decide whether you want a rechargeable collar or one that uses batteries.

The advantage to batteries is that they usually last a lot longer, while rechargeable collar lasts typically up to 3 days before you need to recharge it again. Always pay attention to the low battery indicator, since a nonworking collar means that the fence is down.

I should also mention that if you have more than a single pet or you’re planning on getting more, you need to have the option to add more pets to the system by purchasing additional collars.

The last thing you should consider is the collar size. It shouldn’t be too tight or too loose. Most of the collars are adjustable and can fit a wide range of neck sizes, so measure your dog’s neck and look for a product that matches his neck measurement and his weight.

How to Train Your Dog to Use an Invisible Fence?

Even the best invisible fence won’t do much if your dog doesn’t know why it’s there.

When you just start training your dog, use the flags that come in the box. Your dog doesn’t see the fence and it will be unfair if you don’t mark it somehow, that’s why the flags are there. After a while, you can get rid of the flags, but in the beginning, let them be a visual sign for your dog.

Walk your dog along the safe zone so he can learn where he’s allowed to run and play, but also so he knows where he shouldn’t go. Let him explore his safe radius and get used to the warning tones and the light static corrections.

You may need to lower or increase the collar stimulation depending on your dog reaction, but make sure to praise him with a lot of delicious dog treats when he seems to get the hang of it.

Are Electric Collars Dangerous?

No, shock collars are perfectly safe as long as you use them correctly.

With dog fences, you can choose from multiple correction levels to ensure that you’re picking the right one for your dog’s size and tolerability.

Unlike regular fence, where a dog can climb, jump or dig underneath it, an electric fence means there’s less chance of him running into the road or messing with your neighbor’s properties. It’s also far better than being confined to a kennel or getting caught by animal control.

Your dog will quickly learn to avoid the static correction, while learning to heed the beeps inside the warning zones. This is important for your pet’s safety, freedom, and independence.

If you still aren’t entirely convinced, you can pick a system that has a tone-only mode collar and use that.

Bottom Line

Your dog size, your turf, and the budget you had in mind are all important factors you have to consider before investing in an invisible dog fence.

If you’re looking to save money on traditional fencing or exploring a thoughtful gift for dog lovers, an electric fence is the way to go. Plus, it’s a nice little challenge and it doesn’t look that complicated once you understand how it works. Unlike in-ground fence, I believe anyone can set up a wireless system.

Before picking a dog fence, check to be sure that the collar fits your dog weight and neck measurements. Also, ask yourself whether you need the fence for outdoor or indoor use, as well as how much area you need it to cover.

Once the fence is installed, your dog will benefit from getting more exercise and you won’t have to worry about him getting into trouble.
