Pets and Vets don't like fireworks. Pets are afraid of fireworks, so below are some safety tips and precautions you can take. (Unfortunately if you live in a neighborhood with people who are inconsiderate, try to generate white noise and even give your pet a Benadryl to make them sleepy (1 tab over 30 lbs, 1/2 tab under 30 lbs).
