This is very old news... PLs refer to my post dated September 2020.

Four Covid-19 sniffer dogs have begun work at Helsinki airport in a state-funded pilot scheme that Finnish researchers hope will provide a cheap, fast and effective alternative method of testing people for the virus.
A dog is capable of detecting the presence of the coronavirus within 10 seconds and the entire process takes less than a minute to complete, according to Anna Hielm-Björkman of the University of Helsinki, who is overseeing the trial.
“It’s very promising,” said Hielm-Björkman. “If it works, it could prove a good screening method in other places” such as hospitals, care homes and at sporting and cultural events.

PS: Dogs were long known and used for the detection of disease. They do have the ability to detect certain types of cancer. Dogs have nearly 220 Million scent receptors, against 5 Million for a human. Also their receptors are 10,000 times more accurate than ours.
Even in the UK, they started training dogs for Covid detection since last March. I haven't read about the outcome.
