Smart Dog' in-ground pet fencing systems set the standard for results you can trust. Not a rocket scientist? Don't sweat it'installation is a snap in only three basic steps. Smart Dog systems consist of a buried yard wire connected to an indoor radio transmitter. When the dog approaches the wire, a special collar worn around his neck delivers a brief, totally harmless correction that discourages him from crossing the boundary. Corrections typically become less frequent as the dog learns his new limits.
