All Creatures Great and Small - Season 3 - Eps 7: Be Prepared
The possibility of war is on everyone's mind with Helen preparing for the privations ahead and Tristan tasked to tape the windows in the event of bombing. Siegfried decides that they should conserve food and heating by eating their meals together, but Mrs. Hall takes his instructions to economize a bit too seriously. James treats Hamish, a sick dog who requires an operation and Tristan, who is tasked with overseeing his recovery, loses him. The vets forgo a posh evening out to treat a stray dog who has had an accident. Tristan is aghast at Siegfried's attempt to pair him with Deirdre Headingley, one of his crony's less-than-attractive daughters.
