All Creatures Great and Small (1978) : 7x3

Tristan's heart is all a flutter because of the lovely Jane Mercer. When he discovers that she sings in the choral society, Tristan develops a fresh interest in matters musical. But strong-willed Jane takes a donkey's owner to task for neglecting the animal, much to the embarrassment of Tristan. Farmer Biggins, meanwhile, baffles all three partners with his strange behavior. A legendary non-payer of vets' bills, he finally meets his match when Granville Bennett - "the finest small animal practitioner in the north" attends his tom cat and manages to get Biggins to settle his outstanding account in full.
