One Man And His Dog is to move to BBC One - but will come to an end as a programme in its own right after 37 years.
The sheepdog trail competition is to be absorbed into the popular Sunday evening rural affairs show Countryfile, which has an audience of more than six million viewers.
The BBC said that becoming part of Countryfile was "the natural new home" for the show.
The corporation axed One Man And His Dog as a regular series in 1999 which caused a stir with viewers, but it has continued to be seen on BBC Two over the years with special shows. The current host Matt Baker is also the presenter of Countryfile.
During its new tea-time slot viewers old and new will be able to enjoy the nail-biting competition showcasing the time-honoured skills and tradition of sheep dog trialling, alongside reports on the people, places and stories making news in the British countryside provided by the Countryfile team.
Matt said: "I am delighted that One Man And His Dog is coming to Countryfile, showcasing a lifelong love of mine to a much wider audience than in the past.
"I have no doubt these skilful dogs and their characterful handlers will captivate viewers and this unique part of British rural life will be an added joy to Sunday night television."
Bill Lyons, executive editor of Countryfile, said: "One Man and his Dog has been a much-loved part of the BBC's schedule since 1976 and this move to a prime-time slot on Sunday evenings on BBC One reinforces the special place that the programme has in the BBC's coverage of country life."
The BBC said there will also be footage from the competition available on the BBC red button.
In 2011 Channel 4 launched its own coverage of the World Sheep Dog Trials.
