fireworks at the beach area, what worked for Daifuku

Daifuku is 3 years old now and last year was the first time he really panicked. The whole soi started shooting fireworks around 10pm on new year and he tried to climb into the bathroom sink. We live in Thalang so there is always something going off near the beach, and it is not only new year, sometimes the wedding parties go on till midnight. What I did this year was different. About a week before, I started letting him sit in the bathroom with the fan on and a bit of background music. He was not afraid of the room, so when the noise came he already had a place to go. I put a thick blanket on the floor and a few of his favourite treats in a bowl in there. I also closed all windows an hour before. The noise is much less when the glass is shut, and the aircon makes a sound that covers a bit of the boom. He still shook for about 20 minutes but he was not trying to escape. I sat on the floor with him and did not talk much, just rubbed his ears. His vet said some dogs need a prescription for storm nights, but Daifuku was ok with what we did. Every dog is different, so just try and see.
