Weaponized pit bulls, Hollywood hounds: the bizarre world of LA’s canines.

Why carry a gun when you can own a weaponized dog?

Bizarrely, that’s what they do in the toughest neighborhoods of south LA, as British filmmaker Louis Theroux discovers in this documentary. Los Angeles is home to more than a quarter of a million dogs.

He meets some of the characters whose lives revolve around the city’s canines – from pit bulls trained to attack on command to the pampered pooches of Beverley Hills.
