Scientists have uncovered why dogs are scared of loud noises, including thunderstorms, fireworks and sudden bangs.

According to scientists in Norway, noise reactivity in dogs is partially heritable, with various genes to blame in more than 28% of cases. It's thought that almost half of all pet dogs hate explosions, with environmental factors and personal experiences also adding to their fearfulness.

The researchers found that 28% of the firework hatred was genetic and "identified an interesting region on chromosome 17" linked to firework dislike and noise reactivity. Meanwhile, Poodles were said to be most scared of bangs compared to other breeds.

Dr Dan O'Neill, associate professor of Companion Animal Epidemiology at the Royal Veterinary College (RVC), told The Telegraph: "The results of the paper show only medium to low genomic heritabilities for fear of fireworks and noise reactivity estimates.

"So this suggests that even if dog selection programmes were based totally on selecting only from dogs with low fear of fireworks and noise reactivity, then progress towards future generations showing lower levels would be slow."

‌According to Official Kennel Club data last year, over the fortnight that includes Guy Fawkes Night and Diwali, there was a spike of more than a third in the number of dogs that go missing.

In fact, nearly half of half owners say their dog is scared by fireworks, with one in five noticing signs of stress, such as pacing (20%), howling and crying (20%) and excessive panting (18%). An additional 31% notice their dog shivering and trembling during firework displays.

On the back of this research, the Kennel Club is now calling on MPs to reduce the maximum decibel of fireworks to 90 — down from 120.

"Our statistics sadly show that there really are devastating and long-term consequences when fireworks strike dogs with a sense of terror unexpectedly, with thousands of dogs running away, behaving out of character and showing clear signs of fear and distress every year," Mark Beazley, Chief Executive at The Kennel Club, said.

"Whilst we urge Government to consider our recommendations to protect dog welfare, we are also urging caution from owners this fireworks season. Each dog reacts differently and it is important that owners know what do to and how they can help their four-legged friend and keep them safe."
