How It Works

Tennessee Dog Guard® knows just how important it is that your dog leads a safe and happy life.  We provide a safe, affordable alternative to conventional fencing that safely contains your pet. Tennessee Dog Guard® Out-of-Sight® fencing that allows your dog the freedom he deserves while providing you with peace of mind.

We strongly recommend that you view our video below, which provides a friendly yet informative overview for our wireless pet containment systems, the training program and other frequently asked questions.

Tennessee Dog Guard® Out-of-Sight® fencing utilizes a digital radio signal to keep your dog within selected boundaries.  By placing a thin wire underground, our professional installation team creates the safety perimeter designed by you and your Tennessee Dog Guard representative.

A comfortable collar containing a small receiver is worn around the dog's neck.  This receiver works with a radio signal - which emits an appropriate stimulus level as your dog approaches the barrier.  If your dog continues to advance, a second field produces maximum correction to prevent escape.

Because each installation is customized, you define the boundries.  We'll work with you to protect your pet from driveways, pools and other dangerous areas.  Our system can also protect your flowerbeds, shrubs or other areas from your playful pet.

Tennessee Dog Guard® Out-of-Sight® fencing is a safe, affordable alternative to traditional pet fences, and uses a veterinarian approved combination of animal training and state-of-the art electronics to safely train your pet where it can and cannot go.

How Tennessee Dog Guard® Out-of-Sight® Fencing Works

After your signal wire is buried to define the area(s) of containment, boundary flags are setup within the perimeter of the signal wire.  During the early days of training, you walk your leashed dog around the inside perimeter of your pet containment area, and verbal commands are used to train your pet to avoid the boundary flags.  After your system is activated, when your pet enters the reminder zone, 3 to 6 feet from the signal wire, they receive an audio signal and mild correction stimulus warning that they are approaching the boundary.
