What Is a Hidden Dog Fence and How Does It Work?

A hidden dog fence, also called an underground or invisible fence, is a pet containment system that uses a buried wire loop, a transmitter, and a receiver collar to create an invisible boundary around your property. There are no panels, posts, or above-ground hardware of any kind. And unlike many competing systems, DogWatch hidden dog fence systems require no monthly fees or subscriptions, ever. The system you purchase is fully functional from day one.

Here is how the three components work together:

• The boundary wire is buried a few inches below the surface around the perimeter of your yard. It carries a low-level radio frequency signal from the transmitter.
• The transmitter is mounted inside your home, typically in a garage or utility room, and broadcasts the signal through the wire loop. It controls the width of the correction zone and can be adjusted for your property’s specific layout.
• The receiver collar is worn by your dog and detects the signal from the wire. When your dog approaches the boundary, the collar first emits an audible warning tone. If they continue toward the wire, the collar delivers a brief, adjustable static correction. Once your dog is trained, most dogs turn back at the tone alone.

The system works on any lot shape, any terrain, and can be customized with internal exclusion loops to keep your dog away from specific areas within the yard, such as a pool cage, garden beds, or a pond edge.
