Louis Theroux: Street Dogs

 9.55pm RTÉ 2

First of a three-part series on LA’s mutts. 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. Louis Theroux 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 heartbreaking job includes euthanizing thousands of unwanted dogs every year. He also encounters the middle-class Americans who adopt some of these delinquent dogs, as well as 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.
