Animal welfare is a key reason for the ban. Robin Ehl, a veterinarian with the Prague City Police Shelter for Abandoned Animals, explained the harm fireworks cause to pets and wildlife. “Fireworks and firecrackers create intense noise, which animals perceive much more acutely than humans. This often scares them, causing them to run away,” he said. Many lost pets end up in shelters, often injured after accidents caused by their panic.
