The history of dogs

Max Pearson presents a collection of this week's Witness History episodes from the BBC World Service.

We hear about the invention of the labradoodle, the first dog in space and how a Yorkshire terrier called Smoky became the world's first therapy dog.

Author Mackenzi Lee talks about her book, The History of the World in Fifty Dogs. She discusses Napoleon Bonaparte's turbulent relationship with pugs and the first guide dogs in America.

Plus, the guide dog who saved its owner's life during the 9/11 terror attacks and the man who dressed up as a dog to protest life in post-Soviet Russia.
