Safety and security for your pet are now as close as your own back yard! 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 (click for common installation questions). 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. Dog training questions? Innotek's free 800-number hotline provides expert training support—a Smart Dog exclusive! Don’t trust your dog to anything less than Smart Dog!
