what if none of the fans are in heat though? but more seriously I don't think this is a bad idea, apparently the covid-smelling dogs are pretty accurate.
I think the dogs can sniff those aerosols and particles in the air but they can't do nothing about it.
The Virus does infect Animals. The Dogs and Birds are being tested at Airports. Elephants, Bears etc. Maybe these dogs already are on the vaccine.
I might need me one of those... Bring my dog along with me and start yelling at people to get the **** back !
Imagine being able to smell some of the mouthbreathers out there so intensely that you can even smell their Rona through all the other funk. Stuff of nightmares.
