I don't know. You do it to celebrate a new year too. As if the abstract concept of a year knows you're blowing things up in festive celebration.
Fireworks are just very confusing to me, and to all animals. Loud noises are usually a sign of trouble.
Well, celebrate any way you wish, but please remember to keep your pets safe. Fireworks do scare us and it's still very hot outside, so please be sure to keep your pets inside and safe during your Independence Day festivities.
Have fun all and take care.
