After meeting wtih your local DogWatch Dealer to determine the best containment configuration for your pet, a wire is buried in the ground to create the containment area. A Transmitter is then installed in an appropriate location (garage, basement, etc.) and connected to the buried wire. The Transmitter sends a special FM radio signal through the buried wire. Additionally, DogWatch includes both external and internal lightning protection to provide maximum protection for your fence and your home wiring system. Dual lightning protection is not included with other hidden dog fence brands.
In fact it is the only programmable receiver that you can program at the level of training that you will want to implement with your dog.
