A raw fur - raising study about covid-19 ismakingthemediawaves , suggesting that walking your dog will raise your risk of captivate the viral pandemic by a whopping 78 % . But there ’s plenty of reason not to take the field of study at face value , and your headache is well spent on other , more pressing risk .
The research waspublishedrecently in the diary of Environmental Research by a squad of scientist in Spain . They conducted an online survey of over 2,000 people in the country between April and May of this year , right around the time that Spain was facing its first wafture of the pandemic and had enacted a series of restrictions on movement and distancing . People were asked to answer a number of interrogative about their current life , including pet ownership and whether they had ever digest covid-19 .
All told , just under 5 % of view respondents said they had narrow covid-19 at some point . And when the researchers compared rates of covid-19 between people who say they did or did n’t walk a hot dog ( either because they did n’t have a favourite or just did n’t take the air theirs ) , those in the former camp had a slightly higher chance of reporting transmission : 6.9 % versus 4.2 % .

From this , the researchers concluded that walking a domestic dog “ increase the endangerment of transmission of covid-19 by 78 % . ”
There are a few things to direct , but properly off the bat , the above wording is incorrect , even if you assume the findings are precise . These kinds of studies are called experimental research , intend they depend at patterns and trends in a real - living stage setting . While observational studies are a key scene of science , one of their bed restriction is that they ca n’t show a unmediated cause - and - outcome human relationship between the things they ’re trying to observe .
At most , you could say this study suggests that walking a hotdog is associated with a greater risk of covid-19 , not that dog - walking definitely increase your odds of transmission . It ’s worth asking if this choice of words is the result of something lose in rendering , since the authors mention that the newspaper was edited by a third - company translation company .

Leaving aside the language , the real implications of the inquiry are iffy , too . In trying to explain the finding , the author speculate that bounder could be transmitting covid-19 to their owners , having break up the virus from the outside world during their walks . But while dogs have beenshownto carry the coronavirus and sometimes come down with illness as a result , there’sno evidenceto date that blackguard have then transmitted their contagion to other mass . Most of the fourth dimension , it ’s clearly the proprietor who have give the infection to their pup . airfoil and outdoors transmission of covid-19 among multitude have similarly been document but are look at rare sources of contagion .
So for this possibility to be rightful , you would need two unconvincing thing to happen at once — dogs getting infect by being exposed to some contaminated source out of doors , then give the infection to their owner . And you would need this event to happen a lot , if you ’re hop to find a readable level of added risk of exposure . That just does n’t really pass the snuff test , so to speak .
One other theory they present is that people who walk bounder may simply be more prone to other behaviors that increased their risk of catching covid-19 . That ’s more potential , sure . But the data is n’t needfully as rich as it looks . Most fulgent is that half of the documented cases of covid-19 in the work were not confirmed by an actual test and instead based on self - diagnosis . Obviously , it was much tougher to get a covid-19 trial back in the spring , so that ’s no one ’s fault . But it form the data point collected all the shakier , as well as any of the ending that might arise from it .
The premise of the study was n’t to paint dogs as a whipping boy for covid-19 but to await for any behaviour patterns that might explain a somebody ’s risk of infection of transmission . That ’s a perfectly valid goal . But when you ’re await for so many potential patterns , sometimes you terminate up find oneself thing that only seem actual at first glance .
Is it potential that click have been silent carriers of the pandemic this whole prison term ? Few possibilities are ever unfeignedly discount in skill . But scientist usually use a canonical sensory faculty of plausibility to the things they reveal , based on what we already sleep together . If dogs were a major generator of contagion , there would likely be mickle of evidence from other study hint as much , which there is n’t . So for now , it ’s more potential that this study is a one - off fluke than a concrete cause to keep a masque on your cute pooch at all times ( that said , if you do contract covid-19 and own pets , thentaking precautionson their behalf is advised ) .
Besides , even in this study , walk dogs was n’t the most high - hazard activity colligate to catching covid-19 — it was share a home with someone else who had get it . Those hold out with a covid-19 victim were 60 times more likely to contract the viral illness than those without one in their base . Unfortunately , that ’s an added risk that ’s affirm by a lot of evidence , and one much laborious to avoid than simply not walking your dog .
