How Dog Fences Work

How does an electronic dog fence work?

An electronic dog fence uses a hidden boundary wire that carries a harmless FM radio signal to create an invisible “no-go zone” around your garden. Your dog or cat wears a lightweight receiver collar that is programmed to pick up the signal. As your pet approaches the wire, the collar emits a warning beep. If they continue into the zone, it delivers a mild, harmless static pulse to stop them. With structured dog fence training, pets quickly learn to respect the boundary and stay within the safe area.

A hidden underground dog fence, sometimes called an invisible dog fence or freedom fence, is far more reliable than GPS systems or wireless alternatives. Unlike wooden or wire panels, it can’t be dug under or jumped over and doesn’t block views of your lawn, borders, or patio. The system adapts to any garden shape, works around trees and landscaping, and even crosses driveways or paths without disruption. It’s a secure, discreet, and reliable option for keeping pets safe while preserving the look of your outdoor space.

Can dog fences be used for both dogs and cats?

Yes. A dog fence for dogs and cats is suitable for multi-pet households. Lightweight, programmable receiver collars are individually adjusted to the right level for each pet. For cats, because they rarely walk on a lead, we use a gentle indoor training technique to introduce them to the system in a safe, controlled environment before giving garden access. With consistent training, both dogs and cats quickly understand the boundary and enjoy safe freedom within your property

At what age can a puppy use a dog fence?

We recommend starting puppy training on a dog fence system from around 12 weeks old, with 16 weeks being the ideal age for focus and maturity. The important thing to remember is that all dogs are different. Before starting containment training, your puppy should already be comfortable walking on a lead and responding to some basic verbal commands. This ensures they are developmentally ready to understand the warning beep and learn the boundary quickly and safely

Do dog electric fences work outdoors?

Yes. A dog electric fence for gardens is built to work outdoors reliably in all weather. The boundary wire is buried underground and protected from rain, frost, and heat, so it won’t be affected by seasonal changes or lawn care. Collars are fully waterproof to 10 feet, meaning your dog can swim, dig, or play in wet conditions without damage. Even during snow or summer heatwaves, the system continues to function as normal. For added security, every DogFence installation includes surge and lightning protection, making it one of the most durable options for creating a safe outdoor dog fence boundary year-round.

Safety & Welfare

Are dog fences safe, or are they just shock collars?

Yes, a dog fence system is completely safe when installed and used correctly. Some people mistakenly call them dog shock collars, but that’s misleading. DogFence collars deliver only a mild impulse, similar to the tingle from a TENS machine or ab belt, and are designed as a gentle deterrent – not a punishment. They have been independently DEFRA tested, meet UK animal welfare standards, and are not included in the UK e-collar ban.

Each collar is programmable to your pet’s size and temperament, ensuring a safe and tailored level of correction. Built-in safety features such as auto shut-off prevent over-correction. With professional training, pets quickly learn to respond to the warning beep instead, meaning corrections soon become rare.

Are dog electric fences safe for dogs and cats?

Yes. A properly installed dog electric fence for gardens is completely safe for both dogs and cats. DogFence systems are DEFRA-tested, meet UK animal welfare standards, and are not part of the UK e-collar ban.

The “correction” delivered by the collar is a mild impulse, similar to the sensation of a TENS machine or abdominal exercise belt. It is not a punishment but a safe, humane way to modify behaviour and teach pets their boundaries. Levels are fully programmable to each pet’s size, temperament, and personality, so the system is gentle enough for cats and adaptable for multi-pet households.

Each collar is lightweight, waterproof, and designed with built-in protections. The key safety feature is auto shut-off, which prevents over-correction if a pet were ever to remain in the avoidance zone. With professional training, pets quickly respond to the warning beep instead of the impulse, meaning they stay safely contained in your garden with confidence and freedom.

Do dog electric fences hurt pets?

No. A properly installed dog electric fence for gardens does not hurt your pet. The collar delivers a mild impulse, comparable to the tingle from a TENS machine or abdominal toning belt. It’s designed to be startling, not painful, and serves only as a gentle deterrent to stop unsafe behaviour such as leaving the garden or running onto a road.

In practice, most pets only experience the impulse a handful of times. With professional dog fence training, they quickly learn to respond to the warning beep instead and avoid correction altogether. The collars are DEFRA-tested, programmable to your pet’s size and temperament, waterproof, and equipped with safety shut-off to prevent over-correction.

This makes a DogFence system one of the safest and most humane ways to create a dog proof garden, giving your pets freedom while keeping them protected.

Will a Dog Fence Work for Stubborn or Determined Dogs?

Yes — a properly installed DogFence system works for all breeds and personalities, including so-called “stubborn dogs.”

When a dog ignores a fence, it’s almost always due to incorrect collar fit or incomplete training, not the system itself. At DogFence Ltd, we tailor every setup to your dog’s size, temperament, and behaviour, and provide a clear, structured training programme to ensure success.

For determined escape artists, a short refresher training plan usually solves the problem quickly. Because our collars are programmable, waterproof, and DEFRA-tested, they can be adjusted to suit even large or strong-willed dogs safely and humanely.

With the right collar fit and consistent reinforcement, your dog will quickly learn to respect the boundary and stay safely within your garden — without stress or confusion.

Can anxious or nervous dogs use a dog fence system?

Yes. Many anxious or nervous dogs adapt well to a dog fence for gardens when training is introduced gently and positively. At DogFence Ltd, our installers use a gradual method that combines voice commands, warning beeps, and visible training flags. Sessions are short and supportive, helping your dog gain confidence without stress.

Collar levels are individually programmed to suit your pet’s size and temperament. For nervous dogs, we keep the settings especially low and focus on positive reinforcement, praise, and consistency. Most pets quickly learn to associate the beep with the boundary and avoid correction altogether, meaning they feel secure and free to enjoy the garden.

Is a dog fence safe for homes with children?

Yes. A professionally installed dog fence for gardens is completely safe for families with children. The boundary wire is buried underground and the transmitter is mounted indoors, out of reach, so there are no exposed parts for children to touch. The receiver collar is designed only for pets — the mild impulse it delivers is harmless to humans and cannot be triggered without the collar being worn correctly.

DogFence systems are DEFRA-tested, welfare-approved, and not part of the UK e-collar ban, giving parents complete peace of mind. This makes them one of the safest ways to keep pets contained while ensuring your garden remains a secure, child-friendly space.

Installation & Training

Can I install an electric fence for dogs myself?

Installing a dog fence for gardens can be done as a DIY project or by using a professional installer.

For a DIY dog fence kit, the boundary cable is usually laid around the edge of the garden and buried 2–6 inches below ground to protect it from lawn mowers, weather, and wildlife. The cable connects back to the indoor transmitter, which sends a harmless FM radio signal. Finally, the receiver collar is programmed to your pet, completing the setup so that you are ready to train your pet.

While a DIY dog fence installation is possible, it usually means digging the cable in by hand and carefully sealing joins. Some owners lay the wire above ground, but this makes it far more likely to be damaged.

That’s why many owners choose DogFence Ltd for professional underground dog fence installation. We use specialist trenchers and disc cutters to bury heavy-duty cable neatly into the ground — even across tarmac, gravel, or block-paved driveways.

We supply waterproof joins, surge protection, and carry out a full training programme for each pet. The result is a reliable, discreet system that keeps your pets safely contained — without the hassle of doing it yourself.

How Do Dogs Learn the Invisible Dog Fence Boundary?

Training your dog to an invisible dog fence is a gentle, step-by-step process that helps them understand where the safe boundary is. Using a mix of sound, sight, and mild static cues, dogs quickly learn to stay safely within their designated area.

The system works via a buried boundary wire that outlines your garden. Your dog wears a lightweight receiver collar that communicates with this wire. As your dog nears the boundary, the collar emits a warning beep — a clear signal that they are approaching the edge of their safe zone.

If your dog continues forward and crosses the boundary, the collar delivers a brief, harmless static impulse — similar to a light tap on the shoulder. This mild correction captures their attention and encourages them to turn back.

Dogs quickly associate the warning beep with the boundary, learning that turning back keeps them safely inside their garden. Most pets master this within days using positive reinforcement.

The Step-by-Step Dog Fence Training Process

At DogFence Ltd, we use a proven, gentle programme that’s been refined over decades to ensure your dog learns safely and confidently:

1. Introduce the Flags

Visible training flags are placed along the boundary line to give your dog a clear visual marker. These flags help both you and your pet understand where the boundary lies.

2. On-Lead Practice

After the initial professional training, you’ll reinforce learning with short, on-lead sessions for 3–5 days within the flagged area. This helps your dog associate the warning beep and visual boundary.

3. Supervised Off-Lead Sessions

Once your dog consistently stops at the boundary while on the lead, you’ll move to supervised off-lead training, building confidence and consistency.

4. Gradual Flag Removal

As your dog reliably respects the invisible line, the training flags are gradually removed. By this stage, your dog has fully learned to stay within the safe zone — even without visible markers.


Most dogs are fully trained within a week, and many adapt in just a few days.
The keys to success are consistency, calm reinforcement, and ensuring the collar fit and signal strength are set correctly for your pet.

Can I install an electric fence for dogs myself?

Yes, you can. Our DogFence DIY kits are designed for confident homeowners who prefer to install their own system. Each kit includes everything you need for a professional-quality setup — robust boundary cable, full-size training flags, waterproof cable joins, detailed instructions, and ongoing telephone support from our technical team.

The installation process is straightforward: the cable is laid around the perimeter of your garden (either buried a few inches below the surface or attached along existing boundaries such as fences or walls) and connected back to the indoor transmitter. Once the system is tested, your pet’s receiver collar is programmed and ready for training.

While DIY installation is a cost-effective choice, it’s important to allow enough time for careful layout planning and thorough joining of any cable connections. The wire must form a continuous loop for the transmitter to send a signal, so precise handling is key to long-term reliability.

For smaller gardens or simple layouts, self-installation works beautifully. For larger, sloped, or complex properties — or where driveways or multiple zones are involved — we usually recommend a professional installation. Our engineers use specialist trenchers and driveway-cutting tools to bury heavy-duty cable cleanly, ensuring an invisible, durable boundary with built-in lightning protection and a lifetime equipment warranty.

How will the dog fence wire cross my driveway?

The dog fence boundary wire crosses a driveway by being installed discreetly beneath the surface. The method used depends on the driveway material to ensure a seamless and durable result.

Here’s how a professional installation handles different driveway surfaces:

Hard Surfaces (Concrete, Tarmac, Block Paving): A fine, shallow groove is cut into the surface with a specialised saw. The electric dog fence wire is placed inside this groove, which is then sealed with a professional-grade filler that matches the driveway. This makes the wire completely invisible and protects it from vehicle traffic.

Soft Surfaces (Gravel, Grass, Dirt): The invisible dog fence wire is buried just a few centimetres deep using a professional cable plough. This ensures the wire is out of sight and safe from damage.

How Do I Take My Dog for a Walk with a Dog Fence Installed?

It’s one of the most common questions we’re asked — and the good news is that walking your dog with a dog fence installed is easy and stress-free.

With simple, consistent practice, your dog learns that crossing the invisible boundary is only allowed when they’re on a lead and with you. Most dogs master this routine within 7–10 days.


The Key Rule: Reverse Training

We use a technique called “reverse training.”
It teaches your dog to understand the difference between being safely contained in the garden and going for a walk. Your dog learns that they may only cross the boundary under three clear conditions:

  1. The dog fence collar is removed.
  2. They are on a lead and under your control.
  3. They receive a specific command from you to cross.

This clear distinction ensures your dog stays safely contained at all times, while still enjoying freedom and walks beyond the garden.


Step-by-Step Guide: How to Leave the Garden

Follow this same calm, structured routine every time you go for a walk:

  1. Remove the Collar – Always take off the receiver collar before leaving the property.
  2. Attach the Lead – Clip on your dog’s regular lead or harness.
  3. Pause and Command – Stop just before the boundary line. Give a clear cue such as “walk” or “go.”
  4. Cross the Line – Step confidently across the boundary, keeping your dog close beside you.
  5. Praise and Reward – Once outside, give verbal praise or a small treat to reinforce the behaviour.

When returning home, reverse these steps so your dog understands that the boundary is back in effect.
Consistency builds confidence — and makes the process second nature for both of you.

Watch our video demonstration with Lionel to see how quickly dogs grasp this simple routine. Watch here on How to take your dog for a walk with a dog fence.


Why This Method Works

This method eliminates confusion and strengthens your dog’s understanding of the invisible boundary.
By always associating the same actions — collar off, lead on, verbal command — with leaving the garden, your dog learns that the dog fence remains active at all other times.

The result?
A confident, well-trained dog who enjoys safe off-lead time in the garden and calm, happy walks with you.

Is DogFence Cheaper Than Traditional Fencing?

Usually, yes — especially for large or complex gardens.

Installing traditional fencing around a one-acre property can cost several thousand pounds, and even then, determined dogs may jump over, dig under, or damage it.

A DogFence hidden containment system secures your entire garden at a fraction of the cost, without affecting your views, landscaping, or garden design.

Installation is quick, maintenance is minimal, and there are no ongoing repair or replacement costs like you get with wood, wire, or mesh fencing.

In most cases, customers save hundreds — even thousands — of pounds compared with installing new physical fencing, while enjoying a safer, more flexible solution for their pets.

What Are the Ongoing Costs of a DogFence System?

Almost nothing — DogFence systems are exceptionally low-cost to run.

The only regular expense is replacing the collar batteries, which last between 6 and 24 months depending on the collar type and the number of pets you have.

The transmitter uses just around 25p of electricity a day, making DogFence one of the most cost-efficient pet containment systems in the UK.

There’s no servicing or maintenance plan required — simply check your pet’s collar fit and battery level regularly to keep the system running perfectly year after year.
