Asher’s remarkable nose has already been trained to sniff out a number of human diseases like cancer and malaria. Now a joint research project with the London School of Hygiene and Tropical Medicine and Durham University is seeing whether they can detect Covid-19.

We now know, scientifically, that diseases change body odour, and, you know, dogs are incredibly good at sniffing – and we all know that – but they’re also very good at learning as well. And so they can learn the smell of a particular medical condition. We now know that dogs really can do this really well, so we’re really hopeful that the dogs will be able to do this with Covid-19.
