How Does an Underground Dog Fence Work?

The 3 working components of a dog fence include the transmitter, the boundary wire, and the collar(s):


1. The Transmitter

The transmitter broadcasts the signal, and is often installed in a discreet and easily-accessible location. Garages, sheds, and basements are often the main locations. At the transmitter, customers can make adjustments if needed.


2. The Boundary Wire

The transmitter broadcasts the signal through the boundary wire, which is buried approximately 5-6 inches underground during the installation. Because it is essentially one wire that must leave the transmitter and return back to the transmitter, there is a neutral, twisted wire that runs from the transmitter to the boundary, ultimately completing the loop. The wire emits the signal received from the transmitter. Tall, orange flags are put into the ground to visually remind the dog of the boundaries throughout the training process.


3. The Collar(s)

Depending on the transmitter selected and installed, the dog's collar will activate either a few feet before the wire, or directly overtop of the wire. Remember, flags will be present during the training process to help your dog with visuals! The dog is first warned audibly, and is gently corrected if the fence is further challenged, ultimately reminding the dog of the boundary.
