We used to have large firework parties at my home when I was a kid, with about 100+ people attending. Our dogs (German shepherds) didn't have a problem with them.
My husband and I were commenting that there has been very little firework activity in our neighbourhood this year. On Saturday a home in one of the nearby roads put on a spectacular display, which we viewed from our lounge window. It lasted about 20 minutes and must have cost a small fortune.
