I read somewhere that if you rub your pets hair with Bounty dryer sheets, it will help. I've tried it on my peke, but he has sooo much hair that it didn't do anything for him. He comes and jumps into my lap at the first rumble of thunder. It doesn't seem bo bother my chihuahua yet. He's one year old, but he learns behavior from Shanghai. LOL I don't like to give drugs to my furbabies. The heartworm and flea meds are enough. Here in FL I use them all year round.
