Episode Three - S1.E3

This time the team looks at the special relationship between people and dogs. How much of our pets' behaviour and personality is as a result of their nature and how much comes from us? Looking at both ends of the lead, the team delves deep into the psychology of the human/dog relationship. They discover how dogs have evolved to read us better than any other creature on the planet, outperforming even our closest living relative, the chimpanzee.

The team explores the UK's top ten breeds, investigating what makes them the most popular pooches. They also take a look at the future of dogs and at emerging crossbreeds, such as the Labradoodle and Cockapoo, that are becoming increasingly popular.

Ruth Goodman digs deeper into the history of Greyfriars Bobby, one of the most famous dogs in the world. This loyal dog kept vigil at his master's grave for 14 years. She also visits a pug dog welfare and rescue association celebration to reveal why these lapdogs have their owners wrapped around their little paws and she travels to Swimbridge in Devon, the home of John Russell, the man who created the Jack Russell terrier.
