“Calling B.S. on the ability of a dog to detect viral particles smaller than a wavelength of light.”
Seems someone’s brother-in-law got a big contract for nothing.
Dogs can detect metabolics for a host of things. They have superhuman noses literally 100,000 times better than humans.
Dogs can detect cancer inside a person by the sweat secretions of that person for one example. They do this at a detection accuracy that exceeds the lab test result. As in they detect cancer in people that the lab tests said were negative thus saving their lives.
Dogs can teach a single human out of millions of others across open country side just by the skin particles, sweat droplets and aerosol particles dropped on the ground as the person ran by. Blood hounds are world rebound for this ability even hours or days after that person passed by once trained to their unique metabolics.
Dogs can detect explosive residue in the part per billion range. Word of personal advice never take a military range bag in to a civilian airport the dogs will go right too it they are able to detect that bag held munitions in it months after contact with just the surface of the munition.
Training a dog to smell COVID infected metabolics is a stroke of genius. Only a truly infected person would be shedding those smells and thus need to be found and isolated from society wit large until they recover and are no longer shedding virus everywhere. Dogs are man’s greatest ally proving yet again what good companions they are.
