"Pups, Pigs and Pickle" 9 December 1978
The vets must deal with Kit Bilton, a friendly farmer who grows too attached to the beasts. Siegfried falls foul of the law due to an expired tax disc. James treats the pet of a cantankerous lady. After an early-morning job, Farmer Horner invites James to stay for breakfast. James is horrified when the farmer's mother serves him a large helping of bacon which consists almost entirely of fat. Helen is away visiting her sick Aunt Lucy, so Tristan tries to coax James into going on a pub crawl. Siegfried gets on rather well with Tristan's friend Daphne.
