Picture-Sorting Dogs Show Human-Like Thought 175
ComputerDog writes "A new study shows they can sort photographs into categories in a similar way to humans. In experiments, dogs were shown photographs of a landscape and of a dog, and were rewarded if they selected the latter using 'a paw-operated computer touch-screen'. Later they were able to correctly categorize dogs shown on an unfamiliar background landscape. '' "
Birds (Score:5, Interesting)
Birds rely heavily on their eyesight to find or distinguish food and prey. Thus, they may be as good or better than dogs, who use mostly hearing and smell. Plus, dogs are partly color blind.

For example, take a piece of food being dropped on the floor just out of her reach behind a barrier. Most dogs would simply shove their snout under the barrier and root at it with their tongue for hours. With this dog though, she only did the snout rooting thing once, stopped, reached under the barrier with her paws trying to grip the food, stopped and finally removed the barrier itself to get at the food.
In my previous experience, only a cat would have ever made it to step 2.
Needless to say, the dog is now quite an escape artist, having deciphered how to use doors, removing collars like houdini and bypassing six foot tall chain-link fences.

On the other hand, virtually the same experiment as the one conducted with dogs was conducted with pigeons, in 1964, by Herrnstein and Loveland. So, someone beat you to it. =)

He also used to get agitated if you wore a hat because he couldn't recognise you if you did, he would even bark at my uncle if he was wearing a hat and stop immediately if he removed it.
Having been a building site dog he developed a strange habit of barking when you called "FIRING!" which they used to do before anyone used a nail gun, he would as a result bark on demand any time any place, quite an amusing party trick.
He also used to have what can only be described as a guilty look that he would give you when he had done something wrong, sometimes he would even give the look before doing something wrong and then go and do it!
All in all I think we are not giving dogs nearly enough credit on the smarts front.

There's not much difference between training a dog to recognize photos of dogs and training a human child to recognize Latin characters. The only difference between us and dogs is neural capacity, learning rules, and societal environment.
What studies like this one do is help us to further understand what those hard-wired rules in animals are, allowing us to get a better grasp of the big learning picture across all forms of life.

Mind that this was a Border Collie [wikipedia.org]. Even if she was small for her kind it caused some consternation among his friends seeing the dog in unfamiliar dog locations.

Another good one is "monkey in the middle". Two humans sit 10 or 20 feet apart, with a small plush toy. One of the humans makes the plush toy wiggle like a small mammal, and peep temptingly from behind his leg or back. The cat crouches low to the ground, his tail lashing with small movements, and his eyes shifting back and forth. When you're least expecting it he springs, and if he caught you off guard, grabs the toy with his claws and stalks triumphantly with it in his teeth and drops it in the middle. The other human then takes the toy and makes it wiggle. If the human has managed to stay focused when the cat leaps, he tosses the toy over the cats head to the other human. The cat then leaps high into the air in an attempt to intercept it - often succeeding [gathman.org].
