"Everyone feels like an expert on their dog," says Alexandra Horowitz, a cognitive scientist at Barnard College and author of the new book Inside of a Dog: What Dogs See, Smell, and Know. But scientists had carried out few studies to test those beliefs--until...
This fall, Hare is opening the Duke Canine Cognition Center, where he is going to test hundreds of dogs brought in by willing owners. Marc Hauser, a cognitive psychologist at Harvard University, recently opened his own such research lab and has 1,000 dogs lined up as subjects. Other facilities are operating in the U.S. and Europe...

Kaminski put Rico to a rigorous test and confirmed that the dog could learn names for more than 200 toys, balls and other items.

They will affectionately run up to people and even wag their tails. In 2003, Hare traveled to Novosibirsk and ran his pointing test on baby foxes. The ordinary ones failed miserably. As for the doglike ones, "they did just as well as puppies right out of the box," Hare says.
