Matt Baker and Charlotte Smith present Countryfile's One Man and His Dog for 2017. The best shepherds and their dogs from England, Scotland, Ireland and Wales go head to head for the coveted trophy. Each team is made up of two competitors - the 'singles' who compete with one dog and, the ultimate in sheepdog trialling, the 'brace', working two dogs at the same time. This year, Countryfile brings the country to the city, setting this rural spectacle in the heart of London on Hampstead Heath. It's the first time sheep have been on the Heath for 60 years. So who will be crowned Countryfile One Man and His Dog champions?
