Before resorting to doping up your dog, do at least try the ignore-the-fear-thing. Treats, playtime, and cuddles can all help distract from the noise too.
Our Sparkie is very nervous around noises too. It gets to the point where we'll put her outside at night to pee and a lone firecracker echoing in the distance will send her running back to the house without ever taking care of her business. But we've found that cuddles and assuring her that everything is okay will calm her down enough. Belly rubs work well too.
And as cruel as it may sound, the ignore-thing worked rather well for us too. By us ignoring the situation Sparkie was forced to find a solution to the problem: She lays quietly down on the rug in the bathroom, the most central and quietest room of the house. Once we found out that she was comfortable there we added a nightlight to the bathroom and now it's her favorite spot to wait out thunderstorms too. Good luck with your pup!
