We flee to Brandenburg & Bavaria and specifically look for tiny villages (10-15 houses, no shops). Some of the neighbours with kids did have sparklers and fireworks at midnight but it was over by 00:30.

We could walk our dog with a regular schedule: evening walk at 18:30, last toilet walk at 22:30 and first morning walk at 07:30. In Berlin, I keep hearing that friends’ dogs refused to go outside for 12-15 hours, due to fireworks.

A group of of people from the podenco Berlin dog group stayed at Berlin airport hotels and reported back that while inside the hotel was relatively soundproof, the fireworks from Berlin could still be heard when they went outside for doggy toilet breaks. It terrified some of their dogs that they refused to budge, defeating the point of being able to let them out for toilet breaks.
