If your dog turns into a different animal every time a firework goes off, you're not imagining it and you're not alone. It's one of the most common things owners bring to me this time of year. Here's why it happens, and what genuinely helps, before the night and during it.

Why it happens

Dogs hear a far wider range of frequencies than we do, and much more sharply. A bang that's loud to us is louder again to them, and it arrives without warning, which matters more than the volume itself. A predictable loud noise, a car backfiring on a street they know, rarely bothers a dog the way an unpredictable one does. The brain treats sudden, random loud sound as a threat signal, because for most of evolutionary history, that's exactly what it was.

It's not just the sound either. Fireworks come with flashing light, a strange smell drifting in, and sometimes vibration through the ground or the walls of the house, several alarming signals stacking on top of each other at once. And because fireworks only happen a few times a year, dogs rarely get the chance to learn that the noise is actually harmless. Each bad experience can also make the next one worse, so a dog who struggled last year is often more sensitive this year, not less, unless something changes in between.

Some dogs are simply wired more sensitively than others too, it's not a training failure on your part, and it's not something they'll simply grow out of without some help.

What helps before the night

The run-up matters far more than the night itself. Build a safe, covered den, under a blanket, in a crate with a cover, tucked behind furniture, somewhere your dog already loves well before fireworks start. Feed meals there, toss treats in during the day, so it's a genuinely good spot rather than somewhere they're shut in once the noise begins.

If you want to try sound desensitising, play recorded fireworks or thunder at a volume so low it's barely noticeable, while your dog does something they enjoy, a chew, a meal, a game. If they react at all, it's too loud, turn it down and try again another day. This only works gradually, over weeks, not days.

Tire the brain earlier in the day with a proper walk or a bit of enrichment, and get that done well before dusk, since a walk during the fireworks themselves is best avoided altogether, more on that below.

On the night itself

Calm and normal is more reassuring than a big fuss. Close the curtains, put some music or the TV on to soften the sound from outside, and let your dog choose where they want to be rather than insisting on the den if they'd rather be near you.

Skip the evening walk if fireworks are likely, a startled dog can bolt, and a surprising number of dogs go missing this time of year for exactly that reason. Double check collars fit properly and microchip details are current, just in case.

If your dog is distressed rather than just unsettled, pacing, panting heavily, trying to hide or escape, that's worth a word with your vet. There are genuine options for dogs who find this genuinely frightening, and there's no need to just grit your teeth through it every year.

If this is a yearly struggle rather than a one-off, it's worth addressing properly rather than just getting through it each time. Confidence and Calmness works on exactly this kind of thing, building a dog's overall resilience to the stuff that spooks them, not just fireworks. Send a message if you'd like to talk it through.
