An Italian town has passed a law requiring fireworks to be silent. It is to ensure the wellbeing of pets. The town felt the welfare of pets was more important than the sound of fireworks. Dogs have sensitive hearing and fireworks cause them to develop something called 'acoustic stress'. Smoke from fireworks can also cause health problems for animals. Vets often report cases of nausea, tremors and anxiety in animals after a fireworks show.
Awareness of the problems caused by fireworks is growing. Germany banned fireworks near refugee shelters to reduce the trauma among refugees. Fireworks cause similar problems for war veterans. The explosions can trigger post-traumatic stress disorder. Not everyone agrees with the idea of silent fireworks. One Italian said: "You need the…thunder. It's an essential part of the fun." He said pet owners should keep all windows closed.
