Now admittedly my dog does not appear bothered by fireworks. But I heard that on Friday and Saturday night Classic FM were broadcasting shows for pets to calm them so left the radio on for her whhiile we went to a display. She appeared chilled on our return. She sleeps in the kitchen and since then have left classic FM on low overnight. She appeared relaxed but she's relaxed anyway so I don't know if it's because she's enjoying it!
Does your dog like music?
