Louis Theroux's LA Stories: City of Dogs

　　Los Angeles is home to more than a quarter of a million dogs from the pampered pooches of Beverley Hills to the pit bull terriers of the projects. In the first programme of his new series, Louis Theroux’s LA Stories, Louis enters the bizarre world of LA’s dogs, meeting the characters whose lives revolve around the city’s huge canine population.
　　In the toughest neighbourhoods of South LA he has a terrifying encounter with a ‘weaponised’ dog, trained to attack on command, and goes on patrol with Dogman, whose mission is to rescue some of the thousands of stray and feral pit bulls roaming the streets.
　　At the city’s biggest animal shelter, Louis meets the hard-pressed staff whose heart-breaking job includes euthanising thousands of unwanted dogs every year. But he also encounters the middle-class Americans who adopt some of these delinquent dogs and the colourful dog training gurus who claim to be able to take the ghetto out of the dog once the dog has been rescued from the streets.
