The subtitle is "Canines seem to detect coronavirus infections with remarkable accuracy, but researchers say large-scale studies are needed before the approach is scaled up." but the first part is not suported by the content of the article:
> But there is just one published journal article on dogs’ efficacy at sniffing out COVID-19, by Volk’s group; he describes it as a pilot study1.
> The dogs identified 83% of positive cases and 96% of negative ones.
> Critics say the German dog study used samples from too few patients. The dogs could be learning to identify the specific scent of the samples rather than of COVID-19 [...]
There are also a few mention of preprints, and other preliminary stuff, but no solid evidence that dogs have "remarkable accuracy".
