Research suggesting increased Covid-19 risk for dog-owners may be barking up the wrong tree
Recent research from the University of Granada in Spain has claimed that people who walk their dog are at higher risk from contracting Covid-19 than people who either don’t have a dog, or have a dog they don’t walk.
The paper suggests that this may be because dogs themselves are vectors for the virus, which ignores the possibility that the association may simply be because people going outdoors more often are more likely to have reported contracting Covid-19.
However the paper didn’t separate out the risk from going outside more frequently from the risk of having a dog. There is little evidence dogs act as vectors for the virus.
There are other problems with how the research was conducted which means we should be cautious when drawing any conclusions from it.
No effort was made to obtain a sample representative of the Spanish population, and the researchers also analysed around 40 variables. This is a relatively high number of variables to test, increasing the likelihood of finding an association between two variables where none exists.
The Daily Mirror and the Mail Online both repeated the claim that owning a dog could increase a person’s risk of catching Covid-19, although the former has since altered its headline, standfirst and main copy.
