Dogs scared of fireworks

My dogs really hate this time of the year, when fireworks drive them crazy with fear and panic. They are usually brave dogs, but when fireworks explode all around us, they get scared, maybe because they cannot fight back or protect themselves from the explosions.

I know some people use fireworks to ward off evil spirits, bring luck the coming year, and a myriad of other reasons, but I have come to hate this time of year also because of their effect on my dogs, who cower in fear every time a firework explodes around us
