Just as you don't need to be a vet to know the difference between a dog and a cat.
I own a dog and it's common sense that a properly trained dog is a reflection of the owner, and when you have a dog you know every other owner and dog in the neighborhood (and the ones that use fireworks have dogs that don't mind fireworks). If you don't enjoy fireworks then you tend not to introduce the dog to fireworks at a young age, and the dog will tend to be afraid of them. Look up "optimal age to train a dog".
