I'm not keen on the notion of a free-for-all, any time, anywhere fireworks culture, but a couple of times a year to keep your animals indoors for the evening seems good to me. I'd be more than happy to see something like that enforced generally, but with the possibility of negotiated exceptions. Here in Bude we have the usual shenanigans around Guy Fawkes night (spread out over too many nights in m'humble) and a half-hour spectacular on August Bank Holiday Monday for Lifeboat Day. Quite a few people bring their dogs to that one!
