I do know someone who would give her dog a mild sedative when storms were coming or predicted, and she said it was all that helped. I don't know what else to offer. My first dog, Sheba, would climb into my parents' bed for thunderstorms, they were the only time she (my brave, smart, best girl) was ever afraid.

However, I will agree that coddling K-Lo would just make it worse. A friend's mother-in-law, C, who was terrified of storms, moved in with them, and their rescue dog, a big Pointer, got worse and trembled more during storms when C was "comforting" Pointer, it was sad.
