Countryfile plays host to One Man and His Dog 2019 as the best shepherds from across the British Isles descend on the Scottish Borders to find out which nation has what it takes to claim this coveted title. Matt Baker and Helen Skelton present proceedings from Bowhill House, as the best youngsters and senior shepherds from England, Wales, Ireland and Scotland are teamed up in a bid to win the trophy for their country. We also find out about the history of Bowhill House and its unique canine connection to rare breed Dandie Dinmont dogs, and how the River Ettrick, which flows through the estate, is at the centre of a project aimed at protecting declining numbers of Scotland's wild salmon.
