Renowned dog behavior expert and New York Times best-selling author Cesar Millan is one of the most sought-after specialists working in the field of dog rehabilitation. From bullying Chihuahuas to timid great Danes, Cesar has an uncanny gift for communicating with dogs and seeing the world through their eyes.

His amazing rehabilitations of aggressive, scared, lazy, compulsive and jealous dogs—and the families that are usually in the dark about how their own behavior contributes to the dogs’ quirky traits—captured the national spotlight when his National Geographic Channel series Dog Whisperer premiered in 2004.
