If your pet is not at all bothered by fireworks then count yourself one of the lucky few! As you have arrived here at this site then the obvious assumption must be that you will try anything to help your pet through the experience with the minimum of stress.
Firework parties no longer occur just in the month of November so if your pet is badly affected by them it will be an on-going concern for you but, if at all possible, plan ahead to help your pets cope.
