Walking with Dogs: A Wonderland Special

This film, by acclaimed director Vanessa Engle, explores our remarkable relationship with dogs. Over a number of months in north London's Hampstead Heath, Engle approached people who were walking their dogs to discover why they have a dog and the role their dog plays in their emotional lives. The people she meets tell their stories, many of which are moving, surprising and profound.
