César Felipe Millán Favela (/ˈsiːzər mɪˈlɑːn/ SEE-zər mil-AHN,[3] Spanish: [ˈsesaɾ miˈʝan]; born August 27, 1969) is a Mexican-American dog trainer.

[9] 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.

Millan was born on August 27, 1969, to Felipe Millán Guillen and María Teresa Favela in rural Culiacán, Sinaloa, Mexico.

Millan grew up working with animals on the farm in Sinaloa where his grandfather, Teodoro Millán Ángulo, was a tenant farmer.

[12] Millan illegally crossed the border into the United States when he was 21 years old, speaking no English and with only US$100, in what he has described as a harrowing journey.

[11][13][14][15][16] He befriended Jada Pinkett Smith shortly after arriving in Los Angeles, and she set him up with one of her friends to learn English.

Jada Pinkett Smith became one of Millan's first clients and supporters when he was working as a limousine driver,[5] providing him with an English tutor for a year.

[18] Millan also opened an East Coast clinic at the Country Inn Pet Resort in Davie, Florida, near Fort Lauderdale.

The documentary television series Cesar Millan's Leader of the Pack aired on the Nat Geo Wild channel from January 5 to March 26, 2013.

is an international touring dog training lecture and stage performance where Millan presents his techniques and philosophy from his television shows and books in front of a live audience.

[28] According to Millan, a common pitfall for American dog owners is to give a great deal of affection with very little exercise and even less discipline.

The programs are not intended as a dog training guide, and[20] each episode contains repeated warnings that viewers should not try the behavior modification techniques at home without the guidance of a professional.

"[19] In 2009, The New York Times attributed Millan's success to his personal sense of balance,[10] describing this as "a sort of über-balanced mien".

[34] Malcolm Gladwell, writing in The New Yorker, said that critics were responding to the "highly edited" version of Millan's approach shown on television, which exaggerates the frequency and intensity that he uses when he disciplines the dogs.

Titchmarsh read out an RSPCA statement saying that "Adverse training techniques which have been seen to be used by Cesar Millan can cause pain and fear for dogs and may worsen their behavioural problems.
