  • The standard model doesn’t have very thick/strong wire
  • For larger areas like 1 or 2 acres, the installation can take some time, especially if you have to prep the ground (cut grass and remove objects like rocks or other obstructions) or install a dedicated powerpoint just for the system. Take this into consideration and consider whether you will get an electrician and/or landscapers in to help with installation. The instruction guide tells you what you’ll need to set up and install the system so don’t worry too much
  • The collar receiver can be slightly large for small dogs between 10-30lbs
  • Test on the lowest setting of static first. The higher levels are usually for the most stubborn dogs. Having said that – 10 levels of static stimulation to choose from instead of only 4 would have been nice, but it’s not a major issue

Best In Ground Invisible Dog Fence System: Buyer’s Guide

What Is A Dog Fence System, and What Are They Used For?

Another name for a dog fence system is a ‘pet containment system’.

They are a system designed and used for keeping one or several dogs inside an area of your yard or property.

This is especially true for dogs that want to try to escape or get out of a yard, or dogs that just need to learn where they can and can’t go.

They usually include a transmitter, and a collar receiver that the dog/s wear, and a boundary line which can be wire, or wireless.

What Is An In Ground Or Invisible Dog Fence System?

An in ground dog fence system, or an invisible dog fence system, is a dog fence system that contains a boundary wire fence.

They are called invisible because the wire going around the boundary of the area you want to contain your dog/s in is buried in a shallow trench in the ground – so it is out of sight and invisible.

Note with an in ground system that you will either have to dig and install the system yourself, or you may pay a landscaper or ground maintenance professional to dig and back fill the trenches for you. This can be an extra time and money cost.

Also note that not all in ground systems have the wire buried. Some owners choose to run the wire above ground along the perimeter – it usually has to be fixed to some form of existing fence or structure.

How Do In Ground and Invisible Dog Fence Systems Work?

Different in ground systems work differently, and you can read the owner’s manual and operating and training guide to find out exactly how.

But, in general:

  • The transmitter is plugged into a nearby power source on a wall
  • The system is laid out above ground first to make sure everything is working
  • The boundary wire is planned out, dug and buried, or attached to a fixed object to enclose the dog’s Boundary Area
  • The collar goes on the dog/s, with Contact Points that touch his/her neck and, once trained, is allowed to roam freely in the Boundary Area. 
  • There’s a radio signal from the Fence Transmitter through the Boundary Wire.
  • You temporarily define the Boundary Area with Boundary Flags for a visual aid in training your dog.
  • When your dog reaches the Warning Zone, the Collar Receiver gives a warning beep.
  • If your dog continues into the Stimulation Zone, a safe stimulation will be delivered through the Contact Points to get his/her attention until they return to the internal zone
  • Other fence operating and safety features effect how the collar reacts to your dog’s movements

In Ground vs Wireless Dog Fence – What’s The Difference?

With a wireless dog fence, there is no boundary wire.

What happens instead is the transmitter wirelessly sets a perimeter boundary for the collar receiver your dog is wearing.

This boundary is usually a circle area from the transmitter.

Wireless dog fences are usually much less consistent, less reliable and overall less effective than in ground dog fences because they rely on the signal – which can be interfered with by many factors such as metal objects, solid objects and the strength and connection of the signal itself to the collar.

Types of In Ground/Invisible Dog Fence Systems?

There’s many ways you could classify in ground systems by type.

The best way might be to classify them by the type of training cue/correction they deliver.

You can have static stimulation (shock), vibration, and tone or beeping as training options.

Some fences have one of these training options, whilst others might have all three.

Features To Look For In An In Ground/ Invisible Dog Fence System

Some of the features you might look for in an in ground dog fence system are:

  • What you get with the standard kit – how much boundary wire for example
  • What can you buy extra for the system i.e. can you buy extra wire, collars, repair supplies, batteries etc.?
  • What area the standard kit covers e.g. 1 and a 1/2 acres
  • What training options the system has – i.e. just static stimulation? Or all three of static, vibration and tone training modes?
  • Within each training mode, what settings and custom programs or levels does the mode have? Are the modes manual or automatic? Are they progressive or fixed?
  • How many dogs can the system support with add on collars?
  • What thickness of wire do you get with the system? 14 gauge is the thickest, whilst 20 gauge is the thinnest
  • What weight and neck size of dog does the collar fit?
  • What batteries does the collar operate on? Rechargeable or replaceable?
  • How long do the batteries last and how often do they need to be replaced?
  • How do the boundary, warning and correction areas work in the system? Are they adjustable? How big are they?
  • Are there any extra features like Run Through Prevention on the system?
  • Are there any safety features on the system?
  • Is the system waterproof?
  • What is the warranty on the system and what are the conditions?
  • What extras do you get in the kit e.g. training flags? Surge protector? etc.

When Might You Use An In Ground and Invisible Dog Fence System?

You may choose to use an in ground dog fence system after the following:

  • Once you’ve worked on building a strong bond with your dog & you have their trust
  • Once you’ve undertaken basic obedience with your dog, or advanced training courses
  • Once positive reinforcement training without electronic training tools has not been effective
  • Once you’ve consulted the advice of a professional dog trainer, and your vet 
  • Once you’ve consulted the laws in your area as to the use of dog fences
  • Once you’ve done your own research on the case studies of use of dog fences

Dog fences can be used as a temporary training tool. Once your dog/s learn the boundaries, the system can be switched off and you may not need to use it again unless your dog starts straying outside the boundaries again.

They don’t have to be a permanent thing.

What In Ground and Invisible Dog Fence System Do I Get For My Dog?

It depends on what features you want.

But in general:

  • Make sure the system will cover the area you need it to
  • Make sure it supports the number of dogs you own
  • Make sure it has all 3 of static, vibration and tone training modes if you want them
  • Make sure it fits the neck size of your dog, and is for the weight your dog is

Can Puppies Use An In Ground and Invisible Dog Fence System?

Ask your vet at what age you can begin using static stimulation and electronic training devices with them.

Some manufacturers might say at 6 months old and over, or for all dogs over 8lbs for example.

Are In Ground and Invisible Dog Fence Systems Safe?

Safety is extremely important with an dog fence. Some safety guidelines for using a dog fence humanely might be:

  • Always always get your vet’s advice or the advice of an animal health expert – nothing is a substitute for professional advice
  • Read the operating guide, instruction/safety manual and training guide that comes with the dog fence system
  • Research yourself how to use dog fence systems effectively and safely
  • Buy from a reputable company who put proper use of the dog fence and the safety of the dog as a priority like SportDOG for example
  • Monitor your dog’s response both mentally and physically to using a dog fence. Take the collar off immediately and discontinue use of the system if you notice any negative implications or reactions

A good dog fence should not cause pain to your dog.

Static stimulation should simply stimulate the muscle and perhaps cause some mild discomfort as a deterrent for going near the boundary you set.

The static function does not need to be used either – tone and vibrate training modes can be used instead.
