One Man and His Dog is a BBC television series in the United Kingdom featuring sheepdog trials, originally presented by Phil Drabble, with commentary by Eric Halsall and, later, by Ray Ollerenshaw. It was first aired on 17 February 1976 and continues today (since 2013) as a special annual edition of Countryfile. In 1994, Robin Page replaced Drabble as the main presenter. Gus Dermody took over as commentator until 2012.

At its peak, in the early 1980s, it attracted audiences in excess of eight million.^[1]

The last regular series aired in 1999 on BBC Two; however, the same year also saw the first of a series of Christmas specials, which continued annually until 2011 and were contested by teams of shepherds from the four nations of England, Scotland, Wales and Ireland, in the three categories of Single, Brace and Young Handlers. The main hosts have been Clarissa Dickson Wright, followed by Ben Fogle (initially with co-host Shauna Lowry), and Kate Humble.

Matt Baker joined the programme as a co-commentator (alongside Dermody) in 2006, and additionally became the main host in 2011. In 2012, the show was broadcast in two parts (the first of which was shown live) in September, and Baker was joined as a main presenter by Michaela Strachan. Dermody remained as a commentator until 2012.

The BBC has continued to broadcast sheepdog trials in a standalone series on BBC Alba – the programme Farpaisean Chon-Chaorach^[2] has covered the Scottish National Sheep Dog Trial, International Sheep Dog Trial and triennial World Trial in its 13 series since 2008.^[3]
