So, why are dogs scared of fireworks? Many dogs are afraid of fireworks – and rightly so. They don’t know where the noise is coming from, it’s loud, they don’t know when the next bang will happen…it’s fear of the unknown, and it can cause your pup to become extremely distressed and anxious.
Dogs experience fireworks much differently than they do other natural loud noises like thunder. Your canine pal at least knows when thunderstorms are imminent because they can sense the dropping barometric pressure and static electricity in the air. Fireworks, however, come without any warning, and are closer to the ground and more vibrant than thunder. Not to mention the fact they’re also accompanied by a distinct burning smell.
If you’ve always thought your dog has superpowers, you’re not wrong. Dogs can hear sound four times the distance of humans and at a much higher frequency. Humans aren’t able to hear anything above 23,000 Hertz, while dogs can hear noises up to 45,000 Hertz. Fireworks may sound jarring or even annoying to you, but they can sound like a massive and very scary explosion to your pup.
The part of the brain that controls smell is also 40 times larger in dogs than humans. Dogs can have as many as 300 million scent receptors depending on breed, compared to a human’s measly five million. So…it’s safe to say the smell associated with fireworks is much more intense to your dog than it is to you.
Fireworks are a sensory overload for dogs, and the unfamiliarity and unpredictability of it all freaks them out.
