Cesar Millan, (born CÃ©sar MillÃ¡n Favela; August 27, 1969) is a Mexican-born American dog trainer. A self-taught expert, he is widely known for his television series The Dog Whisperer with Cesar Millan, now in its eighth 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 (2002â2008) â under construction in a new Los Angeles location as of late 2009. Millan's first three books, including Cesar's Way, all became New York Times best sellers, have cumulatively sold two million copies in the United States and are available in 14 other countries. In 2009, in conjunction with IMG, Millan introduced a monthly magazine also titled Cesar's Way â with the Wall Street Journal reporting at that time that half of American consumers recognized Millan. With IlusiÃ³n Millan, he founded the Cesar and IlusiÃ³n Millan Foundation â since re-named the Millan Foundation. He is working with Yale University to create a children's curriculum based on his work.
