BEHAVIOUR Thunder and Lightning, Very, Very Frightening! Dealing With Noise Phobia in Dogs and Cats Dr Quixi Sonntag, Department of Companion Animal Clinical Studies, Faculty of Veterinary Science, University of Pretoria, [email protected] Definition and signs Noise phobia refers to a profound response to loud sounds such as thunder, fireworks and gunshots. It is characterized by intense avoidance, escape or anxiety behaviours associated with the activities of the sympathetic nervous system. Noise reactive animals that show concern with loud noises but are not phobic are referred to as “fearful” or “reactive”. A phobic animal shows a reduction in behavioural variation and the phobia interferes with day-to-day functioning. These animals are hyper vigilant, hyper reactive and show attempts to avoid what is going on in the environment. A variety of signs are associated with noise phobia/reactivity (Table 1). Noise phobic cats most commonly hide during noisy events and thus their condition is easily overlooked. The same treatment principles applied in dogs also apply to cats. Table 1: Specific and non-specific signs of noise phobia Hiding Panting Escape behaviour Salivation Destructive Shivering, shaking Aggressive Urination Vocalising Defaecation Seeking close physical contact Loss of appetite Attention-seeking Vomiting Hypervigilance Diarrhoea Pacing Mydriasis Freezing Cowering Self-harm Prevalence A study undertaken in 2005 in the UK found that 49% of dogs showed signs of noise phobia. However, only 25% of these dogs’ owners thought that they showed signs of fear, and less than a third of owners seek assistance for their fearful dog. A study in Norway found a prevalence of 23%. vet360 Issue 02 | MAY 2019 | 4 Risk factors Some animals are genetically predisposed to developing noise phobia. Although the condition occurs in animals of all breeds, it is more common in herding breeds and cross-bred dogs. Multiple gene involvement is likely.
