Recently at college we got told about how to deal with dogs and their fears like thunderstorms, We was told that you shouldn't make a big deal over the storm and ignore it because if the dogs can pick up that you are worried about them then they start to feel unsafe and start to panic and become nervous so maybe you could turn on some music or something to try and block out the sound a bit more or play with her and her toys maybe if she see's the other dogs playing she would feel less nervous?

Also I dont know if you can get it in america but Rescue Remedy is meant to work well with nervous dogs and its all natural ingredients so it wont harm your dog
