Halloween and Bonfire Night bring plenty of excitement, colourful lights and celebrations. But once the crowds have gone home, some of those colourful decorations can become a hazard for dogs.
I’m talking about glow sticks, luminous bracelets and glow necklaces.
They’re popular with children at Halloween parties, funfairs and organised fireworks displays. Unfortunately, they don’t always make it home. Some are dropped, discarded or left behind on pavements, grass and footpaths.
As someone who walks dogs around Finchley and North London, I’m particularly conscious of what dogs might find on the ground, especially in the days following a large public event.
And while a discarded glow bracelet might look harmless, it is something I’d rather a dog didn’t pick up.
Are glow sticks poisonous to dogs?
Glow sticks and luminous bracelets contain chemicals that create their distinctive glow.
Many contain dibutyl phthalate (DBP), although the ingredients can vary between products.
According to the UK’s Veterinary Poisons Information Service, the chemicals in these products are generally low-toxicity when accidentally ingested in small quantities.
However, the liquid has an extremely unpleasant taste and can irritate a dog’s mouth, skin and eyes.
Even a small amount can cause a surprisingly dramatic reaction.
So, although a dog chewing a glow stick does not automatically mean severe poisoning, owners should still take it seriously.
Another concern is the plastic casing itself.
If a dog swallows pieces of the bracelet or glow stick, they could cause choking, injury or a blockage in the digestive system. Some glow sticks also contain a small internal glass vial.
Signs your dog may have bitten a glow stick
A dog that has punctured a glow stick or luminous bracelet may suddenly show some of the following symptoms:
- Excessive drooling or salivation
- Frothing or foaming at the mouth
- Pawing at the mouth
- Gagging or retching
- Agitation or unusual behaviour
- Vomiting
- Irritation around the lips, skin or eyes
Symptoms can appear quickly because the liquid tastes so unpleasant.
Although these reactions are often short-lived, don’t assume that every case is harmless, particularly if your dog has swallowed any of the packaging.
What should you do if your dog bites a glow stick?
If you discover that your dog has bitten into a glow stick or luminous bracelet:
- Calmly stop them from chewing or swallowing any more.
- Remove any remaining pieces if you can do so safely.
- Contact your vet for advice, particularly if you are unsure how much was swallowed.
- If your dog is alert and swallowing normally, you can offer a little fresh water to help remove the unpleasant taste.
- If liquid has reached their fur, gently wash the affected area with mild soap and water to prevent further licking.
- If the liquid has entered their eyes, rinse gently with clean lukewarm water or sterile saline and seek prompt veterinary advice.
Do not induce vomiting or give medication unless your vet specifically instructs you to do so.
If your dog is choking, struggling to breathe, showing severe symptoms or may have swallowed plastic or glass fragments, seek urgent veterinary assistance.
You can also keep the packaging or take a photograph of the product to help your vet identify what your dog encountered.

Why I pay particular attention after fireworks displays
It’s easy to think that the main dangers associated with fireworks disappear once the last firework has gone off.
But the following morning can bring different hazards.
Around parks, footpaths and areas used for public celebrations, there may be discarded food, packaging, broken decorations, glow bracelets and other litter.
Dogs explore the world with their noses and mouths. Something colourful lying in the grass can quickly become an object of interest.
That’s why I believe the morning after an organised fireworks display deserves just as much attention as the evening itself.
A few simple precautions can help:
- Watch what your dog sniffs or investigates.
- Don’t let your dog pick up unfamiliar objects.
- Consider a shorter lead in areas with a lot of litter.
- Practise a reward-based ‘leave it’ or ‘drop’ cue.
- Choose a different walking route if your usual area is particularly littered.
For dogs that are already nervous following fireworks, a quieter walk with opportunities to sniff and explore may also be more appropriate than heading straight into a busy park.

What about cats?
Cats can also be attracted to glow bracelets, necklaces and other flexible glowing objects.
They may enjoy batting them around or chewing them.
The liquid can cause the same unpleasant reactions, including excessive drooling, frothing and irritation.
Cats may also lick the liquid from their fur while grooming.
If your cat chews a glow stick, contact your vet for advice and prevent further access to the product.
A little consideration after celebrations
I don’t want to discourage anyone from enjoying Halloween, Bonfire Night or local celebrations.
But I do think we can all be a little more thoughtful about what gets left behind.
If you’re taking children to a fireworks display, make sure their glow bracelets, necklaces and other decorations come home with them.
Dispose of damaged glow sticks properly rather than leaving them on the ground.
And if you’re walking your dog the following morning, be mindful of what may have been dropped the night before.
It’s a small thing, but it helps protect dogs, cats, wildlife and the places we all share.

A final thought
I’ve always believed that a good dog walk involves more than simply covering a distance.
It’s about noticing what’s happening around us, giving dogs time to explore safely and recognising the small things that might put them at risk.
A discarded glow bracelet might seem insignificant, but it’s exactly the sort of thing worth watching for.
Stay safe and enjoy your autumn walks.
