LOS ANGELES — In Cesar Millan’s world, two groups most influence America: politicians and their dogs and Hollywood celebrities and their dogs. "The rest of the population wants to do what they do,” he said. That’s good business for Millan. His National Geographic show "Dog Whisperer” is seen in more than 80 countries. He has three best-sellers and another book due out next month. He’s a frequent guest on talk shows. Now, Millan has added a magazine, Cesar’s Way. The first issue came out this month, with one more planned this year and six next year. Millan dominates the cover, the stories and many of the ads, but the 120-page debut issue offers lots of information. It lists food that can kill a dog, including chocolate, onions, garlic, grapes, raisins, sugarless candy, raw salmon, mushrooms and turkey skin. It also lists people medicine you can give a dog, and tips for traveling, eating and playing. Future issues will look at why homeless people can walk dogs off leashes and why blind people’s dogs are well-behaved.
