Specially trained dogs have been used to detect Covid-19 and that includes on some pretty big tours. Bands like Metallica and The Black Keys have used the service of dogs who are trained to detect Covid-19 in backstage crew members at shows. The process involves crew members sitting down as the dogs sniff out their hands and feet. Metallica used dogs for their 40th-anniversary gigs and Tool is getting ready to do the same for their tour launching in January. Do you think dogs can accurately pick up on someone having Covid-19? Should more tours do this to avoid any potential cancellations?
