What Are Underground Dog Fences?
Ever wonder how an invisible line keeps even the craftiest escape artists in check? Underground dog fences (aka in-ground or wired containment systems) consist of a transmitter, boundary wire buried 3-6 inches deep, and a receiver collar on your dog. As Fido nears the wire’s signal field, the collar beeps a warning—think of it as a polite “hey, turn back!”—followed by vibration or adjustable static if ignored.
- Covers any shape: Snake it around pools, gardens, or driveways.
- Scalable: From 1/3 acre to 100+ with extra wire.
Unlike wireless circles, these hug your exact property lines perfectly.
