Lightning is the #1 Cause of Damage to Underground Dog Fence Transmitters.
The dog fence boundary wire in your yard acts like a giant antenna drawing in any current transmitted through the ground during a lightning strike, even if that strike is hundreds of yards away.
The surge protection built into our underground dog fence transmitters will provide some protection for surges coming through your household wiring. However, it cannot stop the surge that comes through the boundary wire. The PetSafe Pet Fence Lightning Protection is designed to stop the lightning surge before it reaches the dog fence transmitter. Our Pet Fence Lightning Protection Module can be used for any brand of underground dog fence.
