Start small
Loud events are easier when your dog has a familiar safe area before noise begins.
There is no need to rush. A predictable, manageable step is usually more useful than trying to solve the whole situation in one day.
Try this next
Close windows, provide a quiet room and a preferred activity, and speak to a vet early if your dog is severely distressed.
Notice what helps your dog stay comfortable and engaged, then repeat that version before making the situation harder.
Keep it kind and practical
Keep the next step easy enough that your dog can succeed. If you are worried about safety or feel stuck, pause and ask a qualified reward-based professional for help.
