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. '' "

      Previously it was thought that dogs could only catagorize other dogs or people by the tried and true butt sniffing technique. This experiment shows that dogs, possibly due to their proximity to human DNA, have evolved more advanced ways to perceive others.

      It's hotly debated whether mosquitos have transferred blood and DNA from humans to dogs to give them this power, as there are many other methods of transmission. Needless to say, the Bird Flu has helped that process greatly among many other species, but it has yet to be shown that is has factored into the human-dog element.

      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.

    Any animal that couldn't tell the difference between another animal and a rock or between different types of animals would soon become some carnivores dinner or fall off a cliff. Why would anyone (least of all supposedly intelligent researchers) find this ability to differentiate objects surprising? I'd imagine you'd probably have to go much further down the evolutionary tree to find an animal that couldn't do this.

    Of course they do. I'd go so far to say that most predators should show similar tendencies. We use our sight for a lot of things that the average mutt wouldn't use it's sight for, but at the most basic level, it has the exact same function for both of us. Predator/Prey identification, basic navigation, threat recognition and response.

    The examples in the article are all "A dog can tell the difference between a landscape and a dog, even if the dog is on a landscape" which just shows that, like us, their eyes are drawn to the animal before the scenery. Classic response for an animal concerned with predator/prey responses. The mountains are nice, but you have to make sure of the animal first.

    The main differences in visual perception would be dealing with stuff like ranging, depth perception, night-vision, day-vision, etc...All stuff to do with the actual hardware of the eye, not in the basic ability to distinguish between two similar objects.

    This should be obvious from a dog's ability to tell one person from another. I've witnessed similar behavior in herbivores as well, so I'd not be surprised to find that they had the same sort of abilities, though it would be difficult to test.

        Considering that dogs can recognise individuals (and vehicles, and other dogs) at distances of up to half a mile or so, without any time for scent to cover the distance, vision has a great deal more to do with it than scent.

        In my experience, dogs identify stuff first and foremost by vision, and only use scent as a "backup" -- to confirm what they already thought, or to see where you've been (they're just like kids going "Daddy, where did you go today? ...Hey!! Why did you go to the duck pond without me??")

I would suggest wearing wiskers on your pants leg or painting a picture of a rolled up newspaper on your pants leg. Either of those should alleviate the problem. Alternatively, you could try being the bigger person and speak to your dog, but I understand the deserved apprehension you might have about this.

    Up until very recently, I always thought of dogs as generally being playful but incredibly stupid animals outside of spirit-breaking intensive training... at least, until we just got our recent dog, a pit bull/boxer mix. Unlike most dogs I've owned over the years, this one isthe first I known to preemptively develop strategies on the fly under ever-changing conditions. (In other words, she doesn't do the whole "repeat the same process over and over expecting a different result each time" thing.)

    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.

      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.

      My friend's dog outsmarted his mother. She was making a sandwich in the kitchen, and the dog wanted the sandwich in the worst way. He finally ran to the out-of-sight front door, barking like there was someone approaching. When she went to investigate, the dog circled back into the kitchen from the other way and stole the sandwich from the countertop.

      So there's a dog who demonstrated an understanding of strategy, tactics, and deception. He lured her away from the food under false pretenses. He knew the back route into the kitchen was unguarded. Most importantly, he put a multi-step plan together in his little canine brain before executing it.

      Humans don't have a monopoly on thought. We just have all the components of intelligence wrapped up in a meat package that can orchestrate them. If that dog had had opposable thumbs, there's no telling where it would have stopped!

Another possible explanation is that the dog was distracted from the sandwich by a noise at the front door, and then returned to the kitchen to continue begging for the sandwich, only to find it was unguarded -- a happy coincidence from his point of view. Your story doesn't prove the dog predicted the woman's behavior at all.

It knew how to open refrigerator doors with his nose, and after my friend installed a hook-and-eye latch on their refrigerator door, the dog learned how to unhook the latch with his nose, and then open the door.

          And dogs can learn how to "predict" future events. I had a dog that learned to predict trajectories.

          I used to throw a soft playground ball onto our sloped garage roof, and let it rol

            Dogs are pretty good at triangulating stuff. When I train working retrievers, one of the things I do is walk along with the dog wandering where he will, then every so often I throw the training dummy in some random direction, for the dog to retrieve. Almost 100% of the time, the dog will get the angle right even tho the dummy is still in the air when the dog goes for where it will land.

            Experienced gundogs can also read river currents well enough to figure out how far down the bank they need to run to interc
      • My brother and mom have sibling dogs, and they do that sort of stuff all the time. Let's call them Jack and Jill. Jack has a chewtoy and Jill wants it so she runs over to the window, starts barking wildly, Jack runs over to see what she's barking at, and she doubles around and grabs the chewtoy. They hide things from one another. One will look to see if the other one's watching and then try to stash something, and the other will fake "not looking" and then as soon as the one takes off the other will tur

      One of my dogs can open the door to her crate (if it's unlocked), get in and close it behind her, which she often does to get away if another dog is annoying her. The only training she got for that is that I showed her how to do it. Another can close a door behind him if told after he noses it open to get through, however, he is not good at opening it against the swing, which my cat naturally does by pawing it towrds him.

      Even difficult dogs don't need spirit-breaking intensive training. Though, in my opin

      In my previous experience, only a cat would have ever made it to step 2.

      I used to have quite a smart cat with a vocabulary of at least 50 words (at least as far as I could tell). He was an alley cat before we adopted him, and he'd learned a large number of cool skills, including feeding himself from tins, opening doors, and was quite adept at picking up stuff after seeing it once.

      Once I opened the sliding window in the dining room, and he was watching. He liked the cool breeze, so whenever he wanted it, he'

  • What appears to have been missed in all the comments here is that this wasn't just dogs recognizing other dogs. Dogs, as a whole, use far more of their senses than we do to gather information about themselves and other individuals. The dogs in question were being shown flat, 2D images of dogs. We have all probably seen dogs react to movement or sound on television, as if they understood the image they were seeing minus the smells of the thing. This was a static image, no sound, and no smell. How it is
  • Wow. A study proving that dogs can discriminate between things and make decisions.
    No doubt owners of sheep-herding dogs everywhere will be greatly relieved.

    Good thing for all these science-fair-level studies that most of the important problems are already solved.
  • It's well known outside the scientific community that all men are dogs, and all women are bitches, so the similarities are to be expected.

    Yet another example of taxpayer money wasted on rediscovering the obvious.
  • My mother has a maltese terrier/poodle cross that she's had for years, and is utterly obsessive about...I've always said that the main reason why she loves it so much is because it is able to relate to her intellectually.

    The single main reason why I've always hated canines myself isn't because of a lack of intelligence...on that score, they're fine. Said intelligence however is hamstrung by a tendency towards chronic emotional codependency. People call that loyalty, when in reality in most cases it's just
  • "We are starting to see that dogs have some good reasoning abilities," says Range."

    Little surprise to anyone who has trained dogs, specially retrievers. They have very good sight recall and of course even better smell recall/use. Retriever hunt tests [akc.org] test a dog's sight memory. With no training, many dogs will reason their way to a fallen bird by going around areas of tall grass, brush, etc. Silly humans, though, then train and grade them on their ability to blindly push their way through these things i
