“Man’s best friend could soon be man’s best chance at ever setting foot in a stadium again.

Dogs can sniff out the coronavirus with a striking 94 percent accuracy rate — raising the possibility of instant tests at sporting events and airports, according to a new study.

Canine handlers trained eight dogs from Germany’s Armed Forces to discern human saliva infected with COVID-19 from healthy saliva, according to the study, which was lead by the University of Veterinary Medicine Hanover and the Hanover Medical School.

Researchers then set up samples from 1,000 people at random, ordered the dogs to pinpoint the infected ones — and found the animals were accurate 94 percent of the time, according to the study.

The pooches were able to make the potentially life-saving distinction because the virus likely ‘completely changes’ an infected person’s internal chemistry — giving their saliva a different scent, said one researcher involved.”
