South Los Angeles has hundreds of dogs living on its streets, and Louis Theroux spends this episode of LA Stories asking why. He rides along with animal control officers and residents who feed and shelter strays in neighborhoods where abandonment is common, and talks to people who see dogs less as pets than as protection, in a city where crime shapes how residents live. One stop is a training school that caters specifically to owners looking to turn their dogs into a defense against break-ins and violence, a demand that says as much about the neighborhood as about the animals. Theroux keeps his usual approach: quiet, curious questions rather than judgment, letting the people who work with these dogs, and the dogs themselves, explain the situation. The episode treats the stray population less as an animal-welfare footnote and more as a symptom of poverty and fear running through the area, with dogs standing in for both.
