The PetSafe PIF00-12917 2-Dog Stay and Play Wireless Dog Fence System is designed for yards up to 3/4 acres in size. This portable system features a water-resistant battery-operated collar receiver to offer secure, reliable containment. Patented run-through prevention and timeout between corrections help your dog learn his limits quickly and safely. The Stay and Play system consists of a Wireless fence transmitter with power adapter. When the dog approaches near the wireless perimeter, 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.
