Cesar Millan is known for training dogs on TV. What’s less well-known is that he migrated illegally to the US from Mexico and slept rough before making his name.

For the past two decades, Cesar Millan has appeared on television sets around the world. His hit shows centre on his incredible ability to rehabilitate dogs with behavioural issues like aggression or anxiety. Cesar’s preternatural talent has earned him the moniker ‘The Dog Whisperer’. When he was younger living in the Mexican state of Sinaloa, he had a less flattering nickname — El Perrero — which translates to "the dog boy". It was given to him by kids who would bully him for walking around the city followed by a pack of stray dogs.

But dogs have always surrounded Cesar’s life, including those he grew up with on his family farm. When he was 13 Cesar says he heard a mystical voice that told him he would become the world’s best dog trainer. That was the impetus for him to make the treacherous and illegal crossing from Mexico to the US. Once in California, Cesar was homeless and slept under a bridge. He caught the attention of a national newspaper because he would walk large numbers of dogs to earn money; in the interview, he announced that he wanted a television show to teach people about dogs. That show would eventually be The Dog Whisperer, a smash hit on National Geographic. On it, Cesar would not only use techniques to help disobedient dogs, but he’d focus on getting their owners to be more calm, assertive and give the dogs proper exercise.

Cesar ended up travelling the world giving seminars to arena-sized crowds and writing several bestselling books. But, at the pinnacle of his career, his mental health suffered and he tried to take his own life. He’s also been the subject of controversy, with critics questioning some of his dog-training approaches.

Throughout the years, Cesar has been helped by various dogs that he calls "the angels who you can see". Especially two pitbulls called Junior and Daddy who he calls his companions and spiritual guides.
