Researchers at the University of Liverpool have turned to the popular video-sharing site YouTube to study the complex issue of dog bites.

Preventing dog bites is an increasingly important public health and political issue with implications for both human and animal health and welfare. However, it remains difficult for researchers to understand the circumstances leading up to dog bites, with most studies relying on evidence collected after bites happen, such as hospital records and victim interviews.

In a new study published in Scientific Reportsresearchers have, for the first time, used YouTube videos to directly observe and analyse dog bites in situ.

Lead author Sara Owczarczak-Garstecka said: “Online videos present us with an unexplored opportunity to observe dog bites first-hand, something which is just not possible using other methods. Making more use of this type of shared content for research could help us better understand how and why bites occur and contribute to the development of bite prevention strategies.”

Using search terms such as ‘dog bite’ and ‘dog attack’ the researchers sampled 143 videos that were uploaded to YouTube between January 2016 and March 2017. For each video the context of bites, bite severity, victim and dog characteristics were recorded. For 56 of these videos they were also able to analyse the details of human and dog behaviour leading up to the bite.
