In-ground pet fence systems provide an excellent alternative to old fashioned above ground fences. Easy to install, these in-ground digital electronic fence systems use pet safe audible tones, vibration and or stimulation to train your pet to stay within the boundaries that you set. Whenever your pet nears the parameter of the area, the fence transmitter sends signals to the receiver collar around your pet’s neck, triggering audible tones and safe static stimulation. This teaches your pet to avoid leaving the protected area using safe digital electronic containment training technology. Please click here if you need professional installation and boundary training.
