I had a dog one that loved fireworks. When I was lighting a fuse, she would bark at me to hurry up. She knew when it lit, and then would run away.
She also stood at the end of the driveway while I shot bottlerockets at her. They were always too fast, but she loved trying to catch them and would bark at me if I wasn't lighting them fast enough. She'd get down into a stalking/hunting pose while I lit them.
We'd light firecracker packs and toss them into the yard and she'd make big jumping arcs over the pack while they were going off.
