Which household pet can live to the ripe old age of 140? Which dog did its war service in the trenches during the First World War? What animals arrived on a Scottish island as 'refugees' from the Spanish Armada?
Each week Desmond Morris and Sarah Kennedy explore the relationship between people and the animals in their lives.
Today Sarah meets the dog which has become a 'living antique', and an ex-ratcatcher in the mines which looks like a pet lamb!
Desmond investigates the world of the railway horses which hauled almost 80 million tons of merchandise a year, and talks to the world's strongest man about his weakness for small birds. Researchers
