Cesar Millan, (born César Millán Favela; August 27, 1969) is a Mexican-American self-taught, professional dog trainer widely known for his television series The Dog Whisperer, now in its seventh season and broadcast in more than eighty countries worldwide. Prior to The Dog Whisperer series, Millan focused on rehabilitating especially aggressive dogs and founded the Dog Psychology Center in South Los Angeles (2002–2008) — under construction in a new Los Angeles location as of late 2009.
In 2002, after a profile in the Los Angeles Times, Millan worked with MPH Entertainment, Inc. developing a television pilot for the Dog Whisperer with Cesar Millan, a reality television series that follows Millan as he works in the field of dog rehabilitation. The series premiered on September 13, 2004 on the National Geographic Channel. The show would become National Geographic's #1 show during its first season. The show is also known as Dog Whisperer with Cesar Millan or The Dog Whisperer, outside the USA, and is now in its seventh season and broadcast in more than eighty countries worldwide.
The program demonstrates Cesar Millan's application of his philosophy that healthy, balanced dogs require strong 'pack leadership' from their owners, specifically in the form of exercise, discipline and affection (in that order), with Millan demonstrating how owners can achieve and maintain a leadership role with their dogs. The program highlights Millan at work rehabilitating dogs, and is not intended as a dog training guide. Each episode contains repeated warnings that viewers should not try some of the behavior modification techniques at home.
Millan's book Cesar's Way debuted with the show's second season, becoming a bestseller. Millan works with a broad spectrum of individuals, including celebrities Oprah Winfrey, Nicolas Cage, Will Smith and Vin Diesel.
