In April 2020, a University of Pennsylvania research program started training this breed of dog to sniff out Covid-19, hoping to employ them nationwide. Name this breed of virus-sniffing pooch.

Research has found that viruses have specific odors, making them easy to detect by a dog's incredibly keen sense of smell. In addition to disease, dogs are adept at sniffing out drugs, explosives, contraband, and even bacteria that destroy crops. A dog may be man's best friend, but a dog's nose is a dog's best friend.
