One type of dog containment system is the wire dog containment system. This system consists of a wire buried underground around the place to be contained. Flags are placed in strategic locations to give you and the dog a visual reference of the location of the perimeter.

This wire of the wire dog containment system is combined with an electronic containment collar on the dog, which has a receiver that detects when the dog is getting close to the wire. At this point, the receiver emits an audible warning sound. If the dog keeps going towards the wire, then the collar emits a mild electric shock that only gets the dogs attention, and is not harmful. This shock can be compared to static electricity. The intensity of the stimulation increases as the dog keeps proceeding towards the boundaries of the containment, until the dog stops and goes back. This way, the dog quickly learns to stay within the boundaries of the wire.

The installation of the wire dog containment system involves laying the wire around the area to be contained, above the ground. Then you have to dig a thin, shallow trench in the ground, put the wire in, and pat the edges of the earth back over the wire. As the wire has to be a closed loop, any obstacles encountered have to be run through or the wire made to run under existing cracks or drainage pipes to complete the loop. You can either install the wire dog containment system to include the entire area of your house and yard, or only the backyard, or have double-loop installations that cost a little more. However, this double-loop installation gives you the advantage of flexibility in precisely defining an area. You could also combine an electrical fence with a physical one for extra protection.
