 Like some dogs who are afraid of thunderstorms, a lot of them might get freaked out by 4th of July fireworks if they're close enough to hear, see, or smell them. They might hide or shake or try to run away. Some tips to avoid the anxiety. Obviously, don't take nervous dogs to a firework show. If the fireworks are close to home, provide a safe space or a place to hide. Maybe play some white noise or soothing music to drown out the sound.
