WASHINGTON – After nine years and more than 150 episodes, the dog whisperer is pulling the plug on his hit show.

The final season of “Dog Whisperer with Cesar Millan” kicked off Saturday on Nat Geo WILD. It will feature appearances by big Hollywood names like Kelsey Grammer, Jillian Michaels and Hugh Hefner, just to name a few.

Millan took time out of his vacation in Madrid, Spain to speak with WTOP about what to expect from this season.

“I got to be in NASCAR with amazing drivers,” he says. “Those guys are so calm and confident, but when they get out of the car they lose control.”

“It’s funny to work with people who are amazing in what they do, but when it comes to the dog it’s like anybody else.”

Millan also swings by the Playboy Mansion to help the top dog deal with his puppies.
