Dogs can detect people infected with COVID-19, research shows

It’s well known that dogs can be trained to smell and find drugs, missing children or runaway inmates. But COVID-19? Possibly so. According to German researchers, dogs trained to detect the virus in saliva were able to detect which saliva sample had the virus with a 94 percent success rate. Dr. David Geier said that dogs have smell receptors that are 10,000 times more accurate and powerful than humans. It may be a possibility that dogs could help with screenings at airports and sporting events.
