Is it safe for my dog during a lightning storm?

Yes because the transmitter is protected using both internal and external surge protection unique to DogWatch and the receiver collar will only activate when it detects the SafeLink Coded digital FM radio signal emitted from the boundary wire.

Your dog is safe and your transmitter is protected.

The DogWatch System features an internal and external electrical surge protection system. The internal surge protection unit will protect your investment from a surge through the main power supply. The external surge protection box will also protect the transmitter against damage from lightning strikes in your area that may occur during an electrical storm.
