Loveable Canine THE LITTLEST HOBO has proved to be an enduring family favourite over the years. London is an extremely intelligent, wandering german shepherd who walks into a different place in each episode of this long running television series, and solves crimes and helping people in crisis. Then, when his job is done at the episode's end, London declines to be the pet of the people he has helped and departs to continue his cross-country drifting.
