Lightning is the #1 Cause of Damage to Underground Dog Fence Transmitters. Lightning strikes, even miles away, can create powerful surges or spikes which may damage your electronic in-ground fence.
In nearly every case, damage to the transmitter results from power surges or spikes traveling through the Boundary Wire and not the power adapter. 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. 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.
