Been had, this just the first time you’re hearing about it
"Dogs’ noses bear 300 million scent receptors, compared with humans’ 5 million or 6 million. That enables them to detect tiny concentrations of odour that people can’t."
powerful little dudes
Would love to know exaclty how the dog can sniff a virus or symptoms
For now I think this is security theater
Idk why everyone is surprised and suspicious. Dogs have been trained to sniff out certain illnesses for as long as I can remember.
The crazy thing in all this is that there are so many things we think are odorless that dogs can sense..we really are blind creatures out here

For real. I don't think we can even comprehend how adept the senses of other species are. Raptors (birds) and octopus have incredible vision, catfish have a sense of taste that is at least 15x more advanced than ours, elephants have 2x the sense of smell of dogs (which are already much more advanced than ours).
There are animals with senses that we don't even have. Electroreception, echolocation, magnetic detection, radiation detection. There are even beetles that have pyrodetection.

"Pyrodetection" might be sensationalizing it a little bit.. it's more of a heat detection, but they chase after forest fires and lay their eggs in the burning wood.
