Fear of fireworks is one of the most common phobias in dogs: surveys on large populations estimate that between 17% and over 50% of dogs show signs of sensitivity or a true aversion to loud noises (fireworks, thunder, gunshots), with a tendency to generalize the fear from one stimulus to another.

It’s no coincidence that on the noisiest nights of the year—New Year’s Eve above all—there is an increase in dogs going missing, running away, or getting into accidents: reports from canine associations show peaks of lost dogs in the 24 hours following fireworks displays, a sign of how fear of fireworks in dogs is both a welfare issue and a safety concern.

Why Are Dogs Afraid of Fireworks?

Dogs perceive higher frequencies and quieter sounds than we do; sudden, unpredictable noises with no “visible source” are processed by their brain as potential threats, triggering an alarm response.

This reaction may include trembling, hypervigilance, vocalizing, seeking hiding spots, and even escape behaviors. Sensitivity to fireworks also tends to correlate with reactivity to other noises such as thunder or gunshots, which is why a dog that fears fireworks often fears thunderstorms as well.

On a physiological level, exposure to intense acoustic stimuli activates the stress axis (hypothalamus–pituitary–adrenal), increasing hormones such as cortisol and catecholamines; in phobic dogs, this response is faster and stronger, and if repeated over time it can leave behavioral aftereffects.

The Risks of Firework Fear in Dogs

Acute noise-induced stress is immediate: rapid heartbeat, panting, restlessness, seeking contact, or, conversely, avoidance and freezing. During peak events—typical, for example, on New Year’s Eve—escape behaviors increase, raising the risk of injuries, traffic accidents, and getting lost. Owners of dogs affected by this issue have likely observed their pets trying to hide under tables or in tight spaces, often much smaller than their actual size.

Repeated negative experiences can lead to chronic issues: heightened noise sensitivity, anticipatory anxiety, worsening of preexisting disorders, and sleep disturbances. Planning ahead can substantially reduce these risks.

What to Do If Your Dog Is Afraid of Fireworks

The owner’s observation and experience can be helpful, especially if the situation is well-established and the dog has shown these symptoms since puppyhood. However, while some measures may vary depending on breed or individual, there are several good practices that can be applied across a wide range of situations.

1.    Behavioral Remedies

The approach using recordings of fireworks or thunder at controlled volumes—progressive desensitization combined with counter-conditioning (treats, play, relaxation)—is considered the gold standard for reducing noise reactivity. It requires weeks of consistent work and guidance from a professional (trainer or veterinary behaviorist), but the results are well documented.

A practical tip? Start well before the holidays, work in short sessions, and always stay below the dog’s fear threshold; if signs of stress appear, immediately take a step back.

2.    Environmental Remedies

Prepare a safe space at home (blanket, open kennel, dim lighting) where the dog can take refuge; during fireworks, close windows and shutters, use masking noises (white noise, steady music), and maintain a predictable routine with calm, guided interactions. Identification (microchip/collar) and careful management of walks are essential on high-risk evenings.

Among non-pharmacological aids, and always considering individual differences, pressure vests or jackets and calming pheromones (in diffuser or collar form) can help. Evidence on vests is mixed and overall still limited, while pheromones show potential benefits in some situations and should be integrated into a broader plan.

3.    What to Give Your Dog for Firework Fear

In addition to pheromones, some natural supplements have interesting scientific rationale:

·       L-theanine: studies suggest a mild-to-moderate anxiolytic effect in dogs sensitive to storms, with good tolerability. Useful as an adjunct to behavioral therapy.

·       Herbs like valerian and passionflower: these are often recommended; so far, clinical evidence is mixed and not always better than placebo. They should therefore be used with realistic expectations and appropriate monitoring.

·       Probiotics: the gut–brain axis is a rapidly growing area of research. Recent studies and clinical trials on specific strains indicate potential benefits for anxiety, adaptation, and sleep quality, always as part of a multimodal plan.

For severe cases, a veterinarian may consider prescription anxiolytic medications to be used selectively on critical days, often in combination with the strategies outlined above.

CBD and Firework Fear in Dogs

When the fireworks season approaches, it’s natural to wonder whether CBD can help. It is an interesting tool, but it must be used wisely: it does not replace behavioral preparation or environmental measures, and results can vary from dog to dog.

Safety, Administration, and Veterinary Recommendations

In terms of safety, studies in dogs generally show good tolerability at commonly used doses, with occasional increases in ALP (alkaline phosphatase) and rarely any clinically relevant signs.

If you decide to try CBD products for a dog afraid of fireworks, it is essential to:

·       Discuss it with your veterinarian first (clinical profile, current medications, blood tests if necessary).

·       Start with low doses, gradually increasing and planning a well-defined trial before critical periods (not on New Year’s Eve itself).

·       Monitor behavior, sleep, appetite, stool, and, if indicated, blood parameters.
