The PetSafe Stay & Play Wireless Fence for Stubborn Dogs is a powerful, portable pet containment system designed specifically for high-energy, hard-to-train dogs. Using advanced wireless fence technology, this system creates a secure, invisible boundary perimeter with no digging or buried wires required. The circular boundary can be adjusted to cover up to 3/4 of an acre, offering a flexible and accurate wireless fence solution that sets up in just 1–2 hours. Simply plug in the training transmitter, place the included boundary flags, and customize the range to suit your yard or travel destination.

Static-free reentry further reinforces positive behavior.
