Smart Dog® in-ground pet fencing systems set the standard for results you can trust. 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/her neck delivers a brief, totally harmless correction that discourages him/her from crossing the boundary. Corrections typically become less frequent as the dog learns its new limits. Run-through protection is a standard on this model.
