Utrecht University investigates effects of post-vibration fireworks on pets

Last autumn, more than 3,500 animal owners participated in the fireworks survey conducted by Utrecht University's Faculty of Veterinary Medicine. This month, the results of that survey will be published in the scientific journal Veterinary and Animal Science. One of the outcomes of the survey is that two-thirds of participating cat and dog owners indicated that they were already struggling with fireworks in their environment from September onwards and thus fireworks problems for their animal.

‘While it is likely that mostly people with animals who are bothered by fireworks participate in research, the reporting is striking of the length of time their animals experience the effects of fireworks,’ indicates researcher Van Herwijnen. Cats and dogs in the study seem to experience stress or anxiety to a similar extent while hearing fireworks. This applies to more than three quarters of the animals. But even up to half an hour after a fireworks display, the effects shake through: more than half of the animals are still bothered at that time. It is therefore not surprising that a third of cats and more than half of dogs do not want to go outside during a fireworks period. 'Especially for dog owners, this is especially annoying. They not only see the suffering of their animal. There are also physical consequences. After all, dogs need to go outside to relieve themselves. At the Behavioural Clinic for Animals, we have a case study of a dog where vet treatment was needed because it held its urine for a very long time,' says Claudia Vinke of this Behavioural Clinic, also involved in the study.

Lower quality of life due to fireworks

Although addressing fireworks problems in animals is important, animal owners in the study report that treatment has little long-term outcome. Dog owners are more likely to seek advice than cat owners. Half of dog owners report seeking help, versus a fifth of cat owners.

Owners do make an average of six (cats) to nine (dogs) different adjustments to help their animals, such as supporting the animal, giving it nutritional supplements and/or medication. The fact that this approach does not seem to help all animals enough in the long run is worrying because the burden of suffering during fireworks is great for the animal. The animal owners themselves also experience a lower quality of life due to fireworks.

Step-by-step habituation

The researchers point out that precisely choices made early in an animal's life can help make animals resilient to fireworks fear and stress. Less noise-sensitive parent animals and a well-used socialisation period with careful step-by-step habituation to noise seems extremely important in a society where many animals are confronted with fireworks noise for longer periods of time.

Pet behaviour mapping across the Netherlands

In registration and information system PetScan, vets can now also enter and look up diagnoses of special pet behaviour. So this can also be done for anxious behaviour. The scientific community has a great need for information on behaviour. The information entered by vets enables research into desirable and undesirable behavioural characteristics of dogs. Through this and other avenues, scientists work towards healthy and socially bred animals.
