We still have a couple of nights to go.... the display sponsored by our lake ass'n will be Saturday night; and tonight will be the last "legal" night to shoot fireworks (not that legality stops many people). Last night I gave both Ben AND Jimmy* a Composure chewy, and they both did fine, although Ben wouldn't go out after dark to potty.
I think fireworks induce different responses in dogs: some ignore them completely. Some, like our hunting dogs back when I was a kid, got excited about "going hunting". Some are just terrified due to the loud noises; and some, like our former Cattle Dog, felt they were "invading our property", needing a protective response of chasing and barking.
*I gave Jimmy a small dose - it seems as his eyesight fails, he doesn't react the same to certain situations. He's always been bombproof regarding fireworks, and I don't want him to decide to be fearful now....
