To test the dogs' ability, Hare and a team of graduate students put dogs through a variety of games similar to those you might play with young children.  "We don't want to look at cute pet tricks. What we want to know is, what does the dog understand about its world?" Hare said.  Hare has been analyzing our four-legged friends for about 15 years. He says dogs have figured out how to read human behavior and human gestures better than any other species has, even chimpanzees.  "The way they think about their world is that people are superimportant and they can solve almost any problem if they rely on people," says Hare.  Children start relying on adults' gestures when they're about a year old. That's about the same age that dogs start to recognize and rely on humans, too, Hare says.  When both I and Hare tried to direct Hare's dog Tazzie to a cup that had a treat in it, Tazzie took his master's cue and went toward the cup. I was a stranger to Tazzie, so the dog didn't rely on my information.  "He's grown up with me," says Hare. "We do lots of stuff together. He's never met you before, so he's saying, look, if they're both telling me where to go, I'm going to trust the guy who I'm with all the time."  According to Hare, this proves dogs are complex social animals who understand they have different relationships with different people.  "They really narrow in and pay attention to you and they want to know what it is about the world that you can help them with," he says.  Researchers at Duke are studying dogs to better understand their limitations. If they can identify why dogs make mistakes, they believe they can help them improve. That could mean making dogs better at working with people with disabilities or better at working with the military.
