I am with Ratter and others on this. When our dog was a youngster she was petrified of fireworks and other loud noises. We have persevered over the years by not reacting ourselves and gradually she has got used to loud noises, fireworks, and even the doorbell and no longer freaks out. Must say though that I have sympathy for people with animals that do react badly, and indeed the animals themselves. It was necessary for us to help our dog, as we have a golf club nearby that has a display at times and a Council run annual display that is only a mile away from us every year.
