What is an In-ground Pet Fencing system?

There are 3 parts to an In-ground Pet Fencing System:

1. The Transmitter: This plugs into a standard outlet and emits a radio signal.
2. The Wire: Waterproof wire that you bury and connect to the transmitter that makes a boundary to contain your dog.
3. The Collar Receiver: The receiver is worn on your dog’s collar. The transmitter emits a radio signal that travels through the wire. The receiver on your dog’s collar picks up the radio signal and alerts the dog as he nears the boundary (buried wire). If the dog continues toward the boundary wire, he will receive a correction from the radio signal.
