Author Simon Garfield is nothing if not diverse when it comes to subject matter for his 20-or-so books. He's previously written about fonts, time, the lost art of letter writing, and stamp collectors, among many other fascinating topics. His latest book, Dog's Best Friend, draws upon history, science art and the writer's own personal experiences with his beloved black Labrador retriever Ludo, to dissect the enduring relationship between humans and dogs and how it has developed over the centuries.
