And some melatonin which you can get at any grocery type store.
Some folks thought it best to ignore but I treat him like I do a spook, keep asking for what i want and reward what I want while not really acknowledging the spook. So when Buck is afraid I get active in order to try and redirect. As long as he is responsive (come, look here, etc), I leave him be but he has to be mentally "here" and not zone off. His auto-response to fright is to "got to his safe place" in his mind, he gets like a zombie. So I work to keep him from that and to keep asking him to interact in even tiny ways. It helped.

I live lakeside in a vacation town. Out of desperation I started feeding a tiny treat every time a firework went off this year. It worked. No hysterical, terrified mess, just a little low whimpering and then looking at me for distraction/instant gratification. It works for thunder too with my dogs. But you have to be pretty desperate because it does make for some spoiled dogs come August.
My dog (border collie/greyhound cross from the shelter) is the odd one out - neither fireworks or thunderstorms bother him...at all. To him it's just another day/sound. I have owned plenty of dogs in the past who were terrified of that stuff and it was never fun .
I have heard the thundershirts work fairly well.

My dog doesn't even notice thunder but fireworks and guns scare the crap out of her. She almost bolted on me the other night when douchey neighbors started setting off the left over arsenal from 4th of July.
The trick with all of this stuff is trying to get it on or in them BEFORE the stimulus (which is impossible when you don't expect it). It can be tough with thunder because a lot of dogs can sense the storms long before we hear them. A lot of people I know with dogs who get upset by them will leave them in the thunder shirts if there is a chance for them during the day. It can help!
I am lucky because my dog doesn't really get bothered by loud noises. My sister's two dogs are afraid of loud noises fireworks mostly, not so much thunder. The only problem with them is that they don't want to go outside to potty. The owner of the barn where I board has corgis and she uses thundershirts for them. I have seen her use them. The dogs went from whining and being anxious to laying on the couch sleeping in just a few minutes.
