In this Oct. 18, 2012 photo, Cesar Millan walks down to his horse stables with his dogs at his Dog Psychology Center, in Santa Clarita, Calif. At 13, his dream was to become the best dog trainer in the world. At 21, alone and unable to speak English, he crossed the border and lived on the streets for two months before getting a job as a groomer and walker. AP Photo/Mark J. Terrill)
