The original adaptation of the James Herriot books, written by Thirsk vet Alf Wight, ran from 1978 until 1990 and was shown on the BBC.
Channel 5 have commissioned a new series and a Christmas special, which will be filmed on location in Yorkshire.
James Herriot was the pen name used by Wight, who worked as a country vet in the Dales in the 1930s before turning to writing. The first book was published in 1970. Ninety episodes of the BBC series were released, with Christopher Timothy in the lead role. Alf Wight and his wife Joan became good friends with the cast during filming.
Although partners Screen Yorkshire won't confirm which locations will be used for the shoot this summer, it's likely that the cast and crew will return to many of the Dales villages that appeared in the original series.
Askrigg stood in for the fictional village of Darrowby in many of the scenes, and others were shot in Leyburn.
A bed-and-breakfast in Askrigg then called Cringley House, now Skeldale House, appears as the veterinary surgery, and the then-owners were given roles as extras during filming. The King's Arms Hotel in the village appears as the Drovers Arms public house.
The 1985 Christmas special was shot in Richmond, and the gymnasium at the Green Howards barracks was used to film surgery scenes.
In the first two series, Langthwaite Bridge can be seen in the opening credits sequence.
