We all know that dogs can smell pretty much anything, no matter how elusive or faint. Woe to the bad guy who is trying to smuggle drugs or explosives and finds that the cops or TSA people have a trained dog.
We've also learned that dogs can sniff out all kinds of cancer, diabetes, malaria, some types of Parkinsons. They can sense an impending epileptic seizure. The list goes on.
Now a group of scientists at the University of Pennsylvania is training dogs to identify people with covid.
The Munsterlander is particularly good at smelling covid. Here's an article in National Geographic about how they train the dogs to find covid.
