Our first dog was very afraid of fireworks, well, he was afraid of any popping noise, we couldn't even pop our chewing gum. He was very abused by a previous owner. Our vet finally resorted to tranqualizing him. We tried white noise, confined him in the bathroom where their was now window, you name it, we tried it. We didn't want to drug him but this was the only way to keep him safe. You might ask your vet, it's worth the try. Cinnamon is a gun dog, she loves to go hunting so the pops have never bothered her.
