Researchers out of Emory University have spent the past two years training dogs to go into MRI scanners so they could get the first scans of their active brains.
f you sedate an animal, you won’t get a scan of the active brain. So, the scientists had to train the dogs, and when they started getting those scans, they saw amazing activity.
BERNS: “Dogs recognize the scents of people they live with and they have positive feelings for them. ... basically the same things that humans love each other for — things like social comfort and social bonds.”
How are they like us?
Dogs are the only species that have demonstrated that they can learn words in a manner similar to a little kid. It’s not that other species that we think of as being highly intelligent, like bonobos and dolphins, can’t become sophisticated at communicating using symbols, but there’s some nice evidence that dogs are using an inferential strategy, which takes advantage of what’s called the principle of exclusion. They know that a number of objects are named or labeled with a sound, and when a new one is introduced that they do not have a label for, and they hear a new sound that they’ve never heard before, they infer that the new sound must apply to this new object. That has only been observed in human children before. That was a big shocker, and it’s been replicated. It even gets crazier than that—several border collies are using what’s called the principal of iconicity. You can show them a two-dimensional picture, and they will then go fetch the object in the picture. That’s something people thought only kids could do, and that it would only be in a linguistic species that that would be possible.
What are some other new findings about dog intelligence?
There’s a lot of research into how dogs solve problems. For instance, in a new experiment, a dog demonstrated opening a sliding door, using one of two techniques. It turns out other dogs will copy the first dog and use that same technique the very first time they open the door. That is not something that most people would have expected. [A hundred years ago, British psychologist] C. Lloyd Morgan was one of the first people to write about animal intelligence from an experimental perspective. One of the great anecdotes he tells is about how his dog Tony struggled to open a gate, and through trial and error, he slowly learned a solution. It looked like Tony the terrier was a genius, but because Morgan had watched the problem-solving develop, he knew that Tony didn’t understand anything, that it was all chance trial and error. Morgan then concluded that when you see animals doing intelligent things, you must consider that there’s a very low-level mechanism that allowed them to solve the problem. But the new finding is, if he had only shown Tony how to open the gate, Tony could have learned almost immediately how to do it. You make the problem social and dogs do fantastically.

Of course dogs are people too! The surprising part of this is that they needed to do research in order to prove it. However now that they have, I guess that settles it once and for all.

Nah. Dogs ain't people. People wouldn't eat the things my dog picks up of the ground and scarfs before I can get to him.
People don't do shoulder dives and roll around it foul things (the fouler the better) like my dog does before I can get to him.
People don't endlessly run after, get, and bring back tennis balls.
That don't mean my dog doesn't really like me...an vice versa.edit on 10/7/2013 by Phage because: (no reason given)

I see where the doctor is coming from in that I agree that the way society murders dogs is basically psychopathic, but still dogs clearly aren't people. There are a lot of other things that separate people from dogs regardless of there perhaps being a similarity in the forming of attachments. I'd like people to be a bit more sympathetic to dogs with behavioural issues but I'm not sure sensational soundbytes are the way to do it.

Due to the nature of the sport, quick retrieval of loose tennis balls and delivery of the game balls to the servers are necessary for quick play in tennis. In professional tournaments every court will have a trained squad of ball boys/girls with positionings and movements designed for maximum efficiency, whilst also not interfering with active play.
