It's a Dog's world...

...But it wouldn't be nothing, nothing without a homo sapien.

Anyway, interesting NYTimes article about research on the canine brain.

In September, the Army announced that it would spend $300,000 to study the impact of pairing psychiatric service dogs like Jet with soldiers returning from Iraq and Afghanistan with post-traumatic stress disorder. Both the House and Senate have recently passed bills that would finance the training and placement of these dogs with veterans.

But Clive D. L. Wynne, an associate professor of psychology at the University of Florida who specializes in canine cognition and has himself said he met a border collie who knew 1,500 words, takes issue with efforts to compare human and canine brains.

He argues that it is dogs’ deep sensitivity to the humans around them, their obedience under rigorous training, and their desire to please that can explain most of these capabilities. They may be deft at reading human cues — and teachable — but that doesn’t mean they are thinking like people, he says. A dog’s entire world revolves around its primary owner, and it will respond to that person to get what it wants, usually food, treats or affection.

“I take the view that dogs have their own unique way of thinking,” Dr. Wynne said. “It’s a happy accident that doggie thinking and human thinking overlap enough that we can have these relationships with dogs, but we shouldn’t kid ourselves that dogs are viewing the world the way we do.”
