Tweet November 18, 2010 (CNN) — Sit! Shake! Quit barking! Get off the couch! Go find your toy! Ever wonder what your dog is thinking as it gazes at you while you are barking commands? Duke University’s Canine Cognition Center in Durham, North Carolina, is one of the few labs in the country focused on how dogs think.  "We're excited about describing the psychology of our dogs," says professor Brian Hare, the lab's director. "Different dogs solve different problems differently. And what we want to understand is: What is it that either makes dogs remarkable as a species or what is it that constrains the ability of dogs to solve problems?" 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 wit...
