All Creatures Great and Small (TV series 1978-1990)

James Herriot is a vet in Yorkshire, England, during the 1940's. He is assigned to the practice of Siegfried Farnon, who (together with his mischievous brother Tristan) already have a successful business. James undergoes a variety of adventures during his work, which are just as often caused by the characters of the county (including the Farnon brothers) as the animals in his care. - IMDb
