July 31, 2006—Cesar Millan, star of the National Geographic Channel series Dog Whisperer, has garnered much recognition—and caused much controversy—with his tough take on animal training. People, he says, must remain dominant over their pets. (National Geographic News is a division of the National Geographic Society, which is part owner of the National Geographic Channel.)

Watch as Millan immerses a woman and her dog in a pack of pit bulls to help the pair overcome their fear of the breed. Then read an interview with Millan in which he responds to concerns about his methods.
