Dogs are truly amazing creatures who continue to adapt to our changing world and contribute to it whenever they can. The latest canine job is being a Covid sniffer at the Helsinki airport. All it requires of the traveler is to swab their neck with a wipe for a sweat sample which is then presented to one of the dogs. The whole process takes around a minute and is less invasive than other methods and a lot more accurate. When the dogs have a positive reaction to the wipe the traveler is sent to the airport's health center for further testing. The dogs are both cheaper and faster than swabs.
