B “There is nothing more rewarding than taking a pack of 40 dogs to the beach for a pack walk,” says Millan. Cesar Millan, star of the National Geographic Channel’s show Dog whisperer and author of the best—selling bookCesar’s way,has a special gift for working with these animals. Growing up on a farm in Mexico, Millan knew he wanted to work with dogs. His first job, at age 15, was helping a veterinarian(兽医) . He was so good at calming scared dogs and handling all kinds of situations, so people started calling him le perrero, Spanish for “the dog boy.” Since then, he has built a rewarding career around his favorite animal. “My grandfather taught me at an early age not to work against nature,” he explains. In nature,dogs are pack animals. They form a group and follow one leader. Millan’s specialty is teaching people to be pack leaders for their dogs. Everyone in the family should lead, he says. He says a lot of people get it backwards because they don’t realize what dogs really need. So the Dog Whisperer doesn’t just train dogs; he trains owners to understand that their pets need rules. At his Dog psychology Center in Los Angeles, California, Millan also works with dogs whose dangerous behavior has prevented them from finding homes. He teaches them to be loving, gentle pets. Through dog whisperer, viewers can actually see the change in dogs with troublesome behavior. Some dogs go crazy when visitors arrive, for example, while some have more unusual problems. To find the right career, Millan encourages his kids to do what they enjoy. “A lot of people don’t realize I’ve been working with dogs for more than 20 years ——long before my TV show of book. Success followed me because I was following my dream of being the best dog trainer in the world.” 60． Dog whisperer is       .
