Researchers at Ivy League schools are looking into a theory that dogs can detect the novel coronavirus, COVID-19, with their noses. Man's best friend has a sense of smell that is tens of thousands of times more sensitive than humans and CBS's Chip Reid reports that it’s a tool that could be helpful to monitor the spread of the virus. Reid reports that Miss M and Pancho are two of eight Labrador Retrievers working with the University of Pennsylvania's School of Veterinary School of Medicine, where researchers hope to show that dogs can sniff out COVID-19. As you can see in the video above, when a dog detects a particular scent, they press a machine which beeps and they are then rewarded with treat. Dr. Cynthia Otto, the Director of Penn Vet's Working Dog Center tells Reid that dogs have been used to sniff out diseases in the past.
