FIREWORKS MAY LAST only seconds, but for some animals the consequences can continue for days, weeks or longer. As Halloween approaches, perhaps it is time to rethink not just how we protect animals from fireworks, but how we celebrate in the first place.

Every Halloween, we hear familiar advice about helping our pets cope with fireworks. Close the curtains. Turn on the television. Walk dogs before dark. It is sensible advice, and for many animals it makes a difference.

But what does an animal actually experience when a firework explodes nearby? For the person watching, a firework may be a few seconds of excitement, colour and spectacle. For a frightened animal, those same seconds can become part of a much longer experience of fear.

As a behaviourist, I regularly work with dogs whose fear of fireworks has extended far beyond the explosions themselves. Some begin to associate darkness with threat. Others become anxious in the garden, on a particular walking route or when they hear sounds that previously meant nothing to them.

Dogs that once waited excitedly at the front door for their evening walk may become reluctant to leave the house. Their owners are understandably confused. The fireworks have stopped. Why is their dog still frightened?

The answer lies partly in how fear and learning work. When an animal experiences something frightening, it does not necessarily remember only the sound. It can also learn to associate the surrounding circumstances with the possibility of danger. The place, the time of day, the sounds of people may begin to predict another frightening experience. Over time, fear can spread beyond the original trigger.

A dog is no longer simply afraid of a firework. It may become afraid of the possibility of one.

Fear doesn’t end when the sound does

A 2019 study published in PLOS ONE, involving 1,225 dogs, found that while almost three-quarters of dogs affected by firework fear recovered by the following morning, approximately 12% took several days to a week, and over 3% experienced effects lasting weeks or even months.

Research has also documented clear signs of distress during firework events, including panting, restlessness and fearful body postures. When fireworks occur repeatedly and unpredictably, animals may remain anxious and hypervigilant long after the noise has stopped, anticipating the next........
