Pros and Cons of Invisible Dog Fences – How to Choose Wireless/Wired Dog Fences

An invisible dog fence is a brilliant way to give your dog plenty of exercise space, without the expense of a wooden fence!  Also known as wireless, wired or hidden dog fences, invisible fences contain pets safely within a low-level, electrically-charged boundary. It’s also a new technology that’s incredibly convenient, without costing more than the traditional way!


So whichever wireless dog fence you finally choose, you’ll get a great deal and full peace of mind! Here’s how ‘wireless’ dog fences work, and how to choose an affordable, invisible dog fence for your needs:

How invisible dog fences work

Invisible fence systems transmit energy between the boundary line you choose, a home-based transmitter and the receiver on your dog’s collar. The actual boundary fence is made of electric wiring that’s buried about 3 or 4 inches beneath the ground. The transmitter can be placed in a garage or fixed on a wall within your home. And when your dog approaches the boundary line, a tone or vibration will deter them. Your pet will retreat from the boundary and the tone stops.

Low electric charge dog fences

The tone or buzzing sensation felt by the dog is not painful or traumatic. And you can check for yourself if you have any doubt. Just hold the receiver/collar over the boundary line and you’ll feel that the buzzing is ‘surprising’, but not shocking. As all pets are different sizes and temperaments, you set up the electric charge yourself to suit your dog’s weight. This type of fence is a safe and effective way to contain your pet, but leave her free to exercise.

How to choose the best wireless dog fence

Wireless/invisible dog fences are available in a wide range of models, designed to suit pets and their owners perfectly. Here are some of the options available, and my recommendations to help you choose the best model for you.

Degree of electric charge

If you have a large, powerful dog or several dogs of different sizes, you need to be able to deliver the right level of ‘charge’ for each pet. Look out for invisible fences that have several different charge levels, so you can find the best for your dog/s. You can also buy extra receiver-collars from suppliers, and set them for different charge strengths. This is useful to contain various pets within a single, dog-fence system.

Back-up battery

A back-up battery feature isn’t offered with all invisible fences, but I’d definitely recommend you choose a fence with this feature. A battery back-up keeps the fence in operation if you forget to charge the system – something that can happen to the best of us!

Interference levels

Another important issue is the amount of radio interference a wireless dog fence may get, and how this impacts on efficiency. Some receive a lot of interference from neighboring technology, which can compromise a fence’s performance. So try to buy a dog fence with a high capacity and low interference risk for added security.

Shaping your boundary

Depending on the size and shape of your garden area, you can choose different hidden dog fence systems that best suit your needs. For example, some ‘wireless’ dog fences need to be set-out in a fairly round, oval or square shape. But others are more flexible, allowing you to shape the dog-boundary to exclude specific flower-beds, a kids’ play area or a swimming pool.

Best for your dog

Invisible/hidden/wireless dog fences are a brilliant idea for containing a pet, without using a dog-crate or small dog-run! They are not difficult to install yourself, as DIY ‘wired’ dog fences come with detailed instructions and excellent after-sales support. And even if you need to hire someone to do the cable burying around the boundary, the wires only need to go 3” – 4” down. So it’s an easy job that doesn’t require any ‘heavy digging’.

Best for your pocket

Wired dog fences are equally suitable for small yards and large areas up to 100 acres. And they’re ridiculously cheap when compared to any type of metal or wooden fencing. Keeping an eye on your pet playing in the garden, without worrying they’ll escape, is a very relaxing way to spend a pleasant afternoon!
