We put the dog in one of the bathrooms that’s center-most inside, with blankets and music. She still hates it but it’s a lot better than anywhere else. She doesn’t shake nearly as much.
The town fireworks are essentially in our backyard. It’s 20 minutes of WWIII for animals. When she was 1 year old, she was outside by accident when they started and she fled in panic. I went to the first place I could think of that she goes when in doubt, and found her covering her body in water in the middle of the river; like you see animals go in a forest fire.
