New insight into dog fear responses to noise
New research has provided important insight into dogs' fear of noises and their behavioural responses. These responses can be extreme in some cases, distressing to owners and pose a welfare issue to dogs. The findings, published in Applied Animal Behaviour Science, could help improve understanding of the signs of fear and anxiety.
In the study, which was carried out by academics at the School of Veterinary Sciences at the University of Bristol, two approaches were taken. A postal survey of dog owners was undertaken to investigate general demographic factors, as well as a structured interview of a sub-set of owners to gather more detailed information. The aim was to examine the occurrence of, and risk factors for, behavioural responses to loud noises.
It is suggested by the findings that a percentage of owners were not always able to recognise their pets' behaviour as fear-based. Almost half of the owners who were interviewed reported behavioural signs typical of fear, though only a quarter of them described their dog as being "fearful" of noises.
It was found that when dogs were exposed to sounds such as fireworks, gunshots or thunder, the most commonly reported behaviours were vocalising, trembling, hiding and seeking people. It is believed trembling and shaking are more commonly reported because they are similar to fear responses in humans.
It is possible that other signs of anxiety, such as salivation and decreased activity may be under-reported as many owners will not recognise them as signs of fear. Behaviour such as urination and destruction may also go unrecognised and be met with disappointment or anger from owners.
Particular breeds of gun dog such as Labradors, Cocker Spaniels ad Springer Spaniels were found to be less likely to display fear responses to noise than cross-breeds. Origin was also found to be a factor, as dogs living with the owner who had bred them as opposed to a second owner, were found to be less fearful. Researchers suggest that the dog's early life experiences are important in the development of fear responses to noise later on in life.
Researchers reported that less than a third of owners seek professional advice on overcoming the reported behavioural responses. Academics involved in the study have urged vets to increase awareness and point owners in the direction of appropriate sources of help.
Two independent vets have launched a podcast to help owners strengthen their bond with pets. Dr Maggie Roberts and Dr Vanessa Howie, who have worked in both veterinary practice and major charities, are keen to use their experience to enable people to give pets a better life.
