  • 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


  • 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

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

What Is The SDF-100A Designed For?

To prevent dogs running away on small to large properties in a safe, comfortable, and effective way.


How Does The SDF-100A Actually Work?

  • 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

What Might Be The Safest Way To Use An In Ground Dog Fence?

If you want expert advice, speak to a professional like a veterinarian or an animal health expert.

Secondary to that, a reputable in ground dog fence manufacturer should have the health, safety and well being of the dog/s as their first priority.

They should provide you with installation and training instructions on how to install and use their products safely with your pets. It’s very very important an owner understands and knows how to use the in ground fence system properly as it was designed for.

Good in ground dog fence systems come with vibrate and sound/tone training options as well, in case you don’t want to use the static stimulation option.

Some owners like to use their in ground 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.

A static stimulation shouldn’t hurt the dog, but rather stimulate their muscles to cue them not to go near the boundary.

Of course, pay attention to any warnings from the manufacturer in using their in ground fence, and if you notice your dog/s having negative effects from using it, discontinue use immediately and consider seeking professional help/advice.
