Dogs being trained to detect Covid-19 through sweat

Dogs are being trained to detect Covid-19 through sweat. Trials are ongoing in different countries and 14 dogs from the Australian border force are in the middle of training. Dr Susan Hazel from the University of Adelaide's School of Animal and Veterinary Sciences has been working on the programme and told our reporter Louise Ternouth it could be a game changer to identify covid-19 at the border.
