All Creatures Great And Small S01---E08 - "Advice Consent" 26 February 1978.
Tristan and Siegfried have to treat Mr Mulligan's giant dog, Clancy. However, they are all somewhat concerned over the sheer size of the animal. Siegfried, Tristan and Mrs Hall all give James some advice regarding Helen. James takes her to Bolton Castle, where he proposes to her. She accepts, and then James has to face the task of asking Mr Alderson for his permission to marry his daughter. Egged on by Tristan, Mr Biggins entertains the regulars at the Drovers. Mrs Dalby is worried about her cattle, and James struggles to find a diagnosis until he realises that the cows have rings around their eyes, as if they are wearing spectacles.
