Noise reactivity and firework fear in dogs

Abstract

Noise reactivity and firework fear are well-known and often discussed topics among dog owners. The prevalence of noise reactivity varies a lot between different dog breeds; in certain breeds, as many as 50% of all dogs are affected at some level. Even though the prevalence of noise reactivity is high, little is known about the genetic background of noise reactivity in dogs. This article provides a brief introduction to behavioural genetics and the genetics behind noise reactivity and firework fear, some of the animal welfare issues related to extreme fear of noise, and sheds light on the possibilities of reducing the prevalence through systematic breeding.
