I am really tired of the hurtful comments directed at those who have dogs with a fear of fireworks. There are so many accusing dog guardians of neglecting to socialise and train their dog or they are insinuating it is the guardian’s response to the fireworks that makes the dog so afraid. This is despite the fact that dogs (and other animals) across the UK are having heart attacks, seizures and strokes, some of which have been fatal. How can a dog guardian’s response to fireworks possibly elicit such an extreme reaction to fireworks?

And if this is the cause of such extreme fear, what accounts for the deaths of wildlife and farm animals? Are there people ‘coddling’ them too? Let’s not forget dogs in rescue shelters. If it’s our response that creates this fear, then why do rescue dogs show extreme anxiety and try to escape their kennels? They are in there alone most of the time. Such heartless comments are baseless since studies show that there are many factors that contribute to noise sensitivity and a fear of fireworks, as seen below.

Genetics

A study involving over 13,700 dogs in Finland discovered that around 32% of dogs had sound sensitivities and 26% were afraid of fireworks. The scientists in this study also identified a genetic predisposition to a fear of fireworks (Salonen, M. 2020) Blackwell et al. (2013) discovered that twelve breeds or breed types were less likely to show fear responses to noises than cross-breeds and their data suggest that some breeds may be predisposed to fear of loud noises, including fireworks.( Linn Mari Storengen, Frode Lingaas 2015.) Thus, your dog may be afraid of fireworks, due to their genetics.

Pain & health conditions

A study showed that dogs that experienced muscle or bone pain were more sensitive to sudden noises, loud noises and different pitches than dogs who were noise-sensitive but didn’t have pain. (Lopes Fagundes 2018) The same study found that the average age of onset for noise sensitivity in dogs differed between groups. In clinical cases (with pain), the average onset of noise sensitivity was 5 years and 7 months.

“Although the average ages of the dogs at presentation were similar, the average age of onset of the problem was nearly 4 years later in the “clinical cases.” This strong theme of an older age of onset suggests that the pain may develop later in life and that owners seek treatment more readily, perhaps because the appearance of the problem is out of character in the subject. The average age of onset within the control population also suggests that the problem does not simply relate to a lack of habituation as a puppy and that other mechanisms need to be considered for many cases.” (Lopes Fagundes 2018)

Other health conditions can also trigger noise phobias. Conditions such as endocrine diseases, cardiopulmonary disease, neurological problems, and cognitive dysfunction, can potentially contribute to or exacerbate behavioural problems including noise fears. (Bowen J. 2008) So both pain and health conditions can cause a fear of fireworks.

Age

Studies show that fearfulness is most common in dogs aged 4-8 years and that noise sensitivity often increases with age., ( Milla Salonen 2020) Another study that supports this shows that the average age of onset of noise phobias developed around 4 years 7 months of age. Dogs progressing through adolescence also go through a second fear period from around 10-12 months of age. At this time of development, dogs can develop new fears and phobias, including noises like fireworks. As a dog reaches their senior years, ill health and conditions such as cognitive dysfunction disorder (dog dementia) can also cause anxiety, fear-related behaviours and noise sensitivities.

Anxiety

Studies show that dogs most fearful of noises also presented with a higher chance of separation-related anxiety and being fearful in novel situations. These dogs also took much longer to decompress after a stressful event compared to dogs less fearful of noises. (Linn Mari Storengen, Frode Lingaas 2015.) It makes sense that if your dog is already struggling with anxiety, that they are more likely to develop noise phobias.

Survival Instinct

“An extreme avoidance response to a loud firework going off unexpectedly nearby, given the salience of this event and its unpredictability for the animal, can be interpreted as adaptive (‘rational’), an argument which has also been applied to extreme fear responses in humans”. (Davey, 1995) From a survival point of view, it is logical for dogs and other animals to respond in fear to explosions. Why wouldn’t they? They can’t reason that it’s harmless.

It should be noted that studies have found that dogs that attend training classes are less likely to be afraid of fireworks however, it is unknown why this would be the case, as exposure to fireworks sounds is not usually part of the curriculum.

Many dogs have been desensitized to fireworks as puppies and have been adequately trained and socialized, and yet they still develop a fear of fireworks. The fact that dogs don’t develop this fear until around the age of 4 proves that often the fear is due to over-exposure, trauma, anxiety or health issues. If it was solely due to a lack of training or due to the dog guardians’ response to the fear, we would likely see the phobia developing much earlier in the dog’s life.

Therefore, it is hurtful and completely speculative to blame guardians for a dog’s phobia of fireworks. The real blame rests on the shoulders of those who continue to set off loud fireworks, knowing for well the suffering it causes to dogs, pets, wildlife, and even people. – Holly Leake
