SportDOG In-Ground Fence System SDF-100A: Review


Overall, a good fence system for most dog owners and dogs

An in-ground dog fence system with 1,000 feet of wire, 100 flags, 1 Transmitter, and 1 Collar Receiver

It’s designed to keep your dog contained in a yard up to 1 1/3 acres

Installation is very simple – you bury the wire around the perimeter of your yard and plug in the transmitter

The collar receiver offers 4 different levels of static stimulation to match any dogs’ temperament from softer to harder or more stubborn temperament dogs

System also offers a tone and a vibration option

You can add an unlimited number of dogs with the purchase of additional Add-A-Dog® Collar Receivers (SDF-R)

The collar receivers are waterproof

The collar receivers have replaceable 9-volt batteries that last about 6-12 months

There’s a low battery indicator to tell you when the batteries are getting low

Fence Transmitter is powerful enough to cover up to 100 acres of land with the purchase of additional Wire & Flag Kits (SDF-WF)

System has a Wire-break Transmitter alarm that alerts you to possible problems with the Boundary Wire

There’s an Anti-Linger Feature that prevents dog from running down Collar Receiver battery in warning zone

Has built-in lightning protection

There’s a wire chart that tells you how many feet of wire you need for how many acres of land

There’s a wire loop layout that shows you how the zones work when the fence is installed

For dogs over 10lbs

There’s now a 14 gauge (thickest wire) wire model available

Includes a warranty – check conditions at time of purchase


Potential Drawbacks

The standard model doesn’t have very thick/strong wire – only 20 gauge

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.

Some people may want more than 10 static stimulation levels

Some users might experience collar compatibility differences between the 100A and the 100C when using collars from other brands on the system – but, to be fair, the system is designed with SportsDOG collars in mind

Some users can experience difficulties in correctly adjusting the settings to give the dog enough time with the warning beep to walk away from the perimeter wire, before the correction stimulation. you may have to speak to customer service for help with setting this up




SportDOG In-Ground Fence System SDF-100C: Review

Similar to the SDF-100A, except:

Comes with a rechargeable lithium ion battery instead of a replaceable battery

Battery charges in 2 hours, and lasts 1-2 months per charge

Has 7 levels of static stimulation, as well as vibration/tone (compared to the 4 levels of the SDF-100A)

Collar waterproof and submersible to 25 feet

For dogs 8lbs or larger

May come with additional accessories depending on who you buy it from

Not compatible with the SDF-100A or SDF-CT Add-A-Dog® collars (SDF-R, SDF-CTR)




So, the SDF-100C is for people who want a rechargeable battery, additional static stimulation levels, and a submersible collar.


SportDOG In-Ground Fence System SDF-100A: Buyer’s Guide

What Is The SDF-100A Designed For?

To contain dogs 10lbs and over to a containment area of the owner’s choosing (and within the capacity of the transmitter, wire, etc.)


How Does The SDF-100A Actually Work?

Read the instructions that come with the system for confirmation.

But a general description might be:

The transmitter sends a radio signal through the fence wire – which you bury in the ground

You can use above ground flag markers as training guides for your dog during the first training phase

Where you bury the fence wire underground as the boundary is the stimulation zone, the area immediately before that is the warning zone, and the inside safe area where you want your dog to stay is the boundary area/safe zone

Your dog/s wear a collar with a collar receiver, and contact points that touch the dog’s neck

When your dog reaches the Warning Zone, the Collar Receiver gives a warning beep. If your dog continues into the Stimulation Zone, a safe static stimulation will be delivered through the Contact Points to get his attention until he returns to the Boundary Area zone

There’s also sound and vibration training options too.


Who Might The SDF-100A Be For?

Dogs overs 10lbs

Small to large properties up to 1 1/3 acres 

With additional Wire & Flag Kits (SDF-WF), land up to 100 acres (that is the transmitter’s capacity)

With additional Add-A-Dog® Collar Receivers (SDF-R), an unlimited number of dogs can use the system


Who Might The SDF-100A NOT Be For?

Dogs under 10lbs

Properties over 1 1/3 acres, unless your get wire and flag kits

More than one dog, unless you get additional collar receivers


What Do You Get In The SDF-100A Kit?

It depends on the seller you buy from – so, confirm contents of kit at the time you buy.

But generally, the kit might look like:


Transmitter Adaptor

Collar Receiver

Black Collar Strap


1,000 Feet of 20-Gauge Wire

100 Flags

Basic Training Manual & DVD

The manufacturer should provide collar sizing instructions for the dog fence and the dogs using them.


Some Safety Considerations For Using An Electric Dog Fence

Safety is extremely important with an dog fence.

Always always get your vet’s advice or the advice of an animal health and/or training expert – nothing is a substitute for professional advice.

Some general safety guidelines for using a dog fence humanely might be:

Buy from a reputable company who put proper use of the dog fence and the safety of the dog as a priority 

Read and follow the operating guide, instruction/safety manual and training guide that comes with the dog fence system from the manufacturer for operation and safety instructions and guidelines

Pay attention to any warnings issued by the manufacturer

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 that uses static stimulation should simply stimulate the muscle (to the point of reflex) to get the dog’s attention, but should not cause pain (it might be slightly annoying for the dog to act as a small deterrent – but shouldn’t cause pain or harm). It certainly shouldn’t cause a ‘sharp pain’ to the muscle or body. 

To get a safe stimulation level – you can always start from the lowest stimulation level, and work your way up to a level that gets the dog’s attention (such as changing body language when a stimulation, vibration or tone is administered) without any visible sign of pain or harm (such as yelping, or showing signs of stress).

A good dog fence company should give you all the necessary safety, use and training instructions, and should have a dedicated customer service line to help when you being using the fence system.

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

Some owners like to use their dog fence system as a temporary training tool i.e. once their dog/s have learnt the boundaries and are properly training to stay in the yard, they turn the fence off or remove it.

If the dog starts going outside the boundaries again, they use the fence again to re-train their dog.

As a safety precaution for humans as well – make sure to get a qualified company to do an underground utility search and get these utilities marked before doing any digging.
