A hidden wire, buried underground, carries the harmless, low level FM radio signal around the containment area. Your dog wears a receiver on a collar that emits an audible warning, then a mild stimulation, or correction, when your pet gets too close to the boundary. With an indoor dog containment fence, the hidden wire runs around your couch or other containment area and is invisible to the eye.

The Dog Guy's staff provides full training for you and your pet and your pet learns the containment area through voice commands and visual flags that are set inside the hidden fence. Your dog goes through a training session with you for a few minutes each day for about 5 days. With training, the dog remembers the placement of the flags and is taught to stay within the containment area. During the training period, flags are slowly taken away. If your dog goes to within 5-8 feet of the boundary, he will hear a warning sound indicating he's too close to the containment fence. If the dog reaches the boundary, he will receive a mild correction, depending in the intensity level that the collar is set at.
