The PetSafe Wireless Fence is a great way to expand your coverage area and increase your pet’s safety. This fence adds an additional circular-shaped wireless boundary to your existing PetSafe Wireless Containment System, which means you can create a larger perimeter around your home or property. The PetSafe Wireless Fence is compatible with all PetSafe wireless fences and is easy to set up with no digging or wire needed. It is also portable so you can take it with you on the go when you and your pet travel.
