Why your dog is smarter than a wolf

Dogs also excel at imitating people. In one of the laboratories, graduate student Zsofia Viranyi demonstrates with Todor, an enthusiastic little mutt. Todor sits attentively as Ms. Viranyi spins around in a circle and comes to a stop. "Csinal," she says. ("You do it!") Todor does a little 360 on the tiled floor and lets out an enthusiastic bark. He easily imitates Viranyi's bow, lifting of an arm, and other tasks.

The team found that some dogs can even imitate previously unseen actions performed by a person they haven't had close contact with. Other dogs learned how to operate a simple ball-dispensing machine by watching people use it.

"We thought it would be very difficult for dogs to imitate humans," Csanyi says, Chimps have great difficulty doing so, even with their larger brains. "But it turns out [dogs] love to do it. This is not a little thing, because they must pay attention to the person's actions, remember them, and then apply them to their own body."

Dogs' unusual ability and motivation to observe, imitate, and communicate with people appears to be with them from birth. Two years ago, Csanyi's graduate students were given either a puppy or a wolf cub to raise. They fed the animals by hand, coddling and doting on them.

At five weeks, each cub was placed in a room containing an adult and the student who had raised the cub. Both sat motionless. But while the wolf cubs merely sniffed both humans before climbing into the student's lap to sleep, the puppies yipped at their caregivers, licking their hands and trying to establish contact.

Three months later, the canines were given the opportunity to try to remove a piece of meat from under a cage by pulling on a rope in the presence of their caregiver. Dogs and wolves both mastered this promptly. Then the rope was anchored, making it impossible to obtain the meat. The dogs tried a couple of times, then turned to their masters for assistance or cues. The wolves ignored their caregivers, yanking on the rope until exhausted.

"The wolves ... were only interested in the meat," notes Miklosi. "The dogs were of course interested in the meat, but knew that one way to get it might be to figure out what the human wants them to do."

To Csanyi, this proves that dogs have acquired an innate ability to pay attention to people, and thus to communicate and work with them. This is a skill that wolves don't assume even when raised from birth to learn it.

Dogs are "very motivated to cooperate with and behave like people," says Csanyi. "That's why dogs can do things no other animal can do."
