“Everything Americans feel about our dogs is right. But everything we think we know about dogs is wrong.” —Kevin Behan
Things have changed
a lot since veteran police dog trainer and natural philosopher Kevin Behan
wrote those words in 1992. Yet strangely enough (or perhaps not so strangely),
most of the ideas Behan first proposed—that pack formation is a function of
prey size, that the wolf pack is a self-emergent system, that emotion is the
key to learning—have been validated by modern research.
Behan: “My ideas
directly contradict more familiar ones that are currently in fashion, but don’t
let an initial sense of resistance distort my message. If you bought this book
you’re already determined to succeed with your dog or puppy. All you need is a
little dog sense.”
What does Behan
mean by “dog sense?”
I think he simply
means trying to see the world from the dog’s point of view, not our own. This
is what I like to call the difference between anthro-pomorphizing dogs and
dogthro-pomorphizing ourselves.
Dr. Alexandra
Horowitz, who heads the Dog Cognition Lab
at Barnard College (and is the author of the NY Times Bestseller, Inside of a Dog), is keenly aware
of the dangers of anthropomorphism. In 2007, she co-wrote a paper on the
subject with fellow PT blogger, Dr. Marc Bekoff. In it they state: “Domestic
dogs may be a particularly good animal for the study of anthropomorphisms, as
recent evidence supports the speculation that domestication has produced a
species unusually adept at interpreting and producing signals salient to
humans.”
In her most recent
blog article here, Horowitz writes, “The cues we give [dogs] are often subtle.
We might not even know that we are giving a different cue when we rise from our
chairs to go to the fridge, as opposed to rising to take the dog for a walk.
Your dog does.”
She then discusses a recent study
where a group of dogs—well-trained in the art of detecting illegal or dangerous
materials—were brought into a room where no drugs or explosives were hidden.
The dog’s handlers, however, were told that these substances had been hidden,
and were told exactly “where they were.” The dogs gave false alerts, which matched
where the handlers thought the illegal substances were located.
Horowitz: “Either
the handlers [unconsciously] tipped off the dogs to what they thought were the
correct locations ... or the handlers simply misreported what the dogs were
doing. They might have ‘thought’ or ‘sensed’ that they saw the dog alert to a
scent. This is classic confirmation bias: you see what you expect to see.”
Since the dogs were
trained to either bark when finding a targeted material, or to sit and bark,
it’s doubtful that the handlers misreported what the dogs were doing. However,
Horowitz’ comment about confirmation bias does ring true. I have often said
that “Dogs are confirmation bias with a tail ... if they’re in a situation
where there’s nothing interesting going on and someone with a strong enough
desire comes along and wants them to do something, they’ll usually find a way
to do it.”
This brings us back
to Kevin Behan, someone who is more than a little familiar with the process
used to train detection dogs (he even invented some techniques still used by
working-dog trainers today).
In his new book, Your Dog Is Your Mirror: The
Emotional Capacity of Our Dog’s and Ourselves, Behan discusses
the importance of emotion and desire in training detection dogs: “The dog is
trained to become emotionally aroused by one smell versus another. In the
step-by-step training process, the trainer attaches an ‘emotional charge’ to a
particular scent so that the dog is drawn to it above all others. And then the
dog is trained to search out the desired item on cue.”
Behan also says that
over his many years of training detection dogs he’s developed a long “standing,
take-it-for-granted state of awe in regards to what a dog can smell.” Yet in
this case, the dogs’ amazing olfactory senses seem to have been overriden by
something else. What motivated them to ignore what their noses were telling
them was true? Since none of the usual scents that the dogs in this study had
been trained to detect were in the room, what “desired item” were these dogs
drawn to?
The scientists
conducting the study don’t ask. They write, “This confirms that handler beliefs
affect outcomes of scent-detection dog deployments.”
Well, obviously,
there’s a missing piece here. It wasn’t the handler’s beliefs that the dogs were
responding to; their beliefs would have meant nothing to the dogs. But if the
handlers beliefs affected their own behaviors in some subtle way—as Horowitz
says might have happened—then it might have been those behaviors—those
micro-expressions, shifts in body language, the direction of their gaze,
possibly even shifts in breathing—that had an effect on each dog’s performance.
There’s a pretty
simple way to test this. Set up four HD, slow motion video cameras inside the
room to record every breath, micro-expression, etc. that the handlers exhibit,
and run the video for an expert in human body language to examine. If such
micro-behaviors can be detected by such an expert, and if the dog happened to
be looking at the handler at the time these behaviors were produced, then you
might have a clearer answer about how the dogs were reading these oh-so subtle
cues.
However, I would go
a step further and suggest that it wasn’t the handlers’ beliefs or their behaviors, it
was the handlers’ desires—the desire that their dogs find the proper
location of the scents—that led to the false alerts. If there’s one thing that
could make a dog ignore what his sense of smell is telling him is right, it
would have to be the emotional bond he has with his owner or trainer, something
dogs excel at above all other species. In fact, it’s the emotional bonds dogs
form with us that make them such steadfast and tenacious readers of our body
language, etc.
Yet, I would go even
further and suggest that the dogs in this study may have also been picking up
mental images from their handlers about where they believed the substances were
located.
I know this
idea—that dogs can pick up mental images
from humans, especially from their owners or trainers—, may sound
fantastical (even though Dr. Rupert Sheldrake has done extensive research
verifying this idea), I’ve had enough experiences where when I have a quick,
passing mental image of taking a dog for a walk and the dog wakes up from a nap
so that I feel like I’m on fairly solid ground with this. (In fact, one of the
dogs staying with me today just woke up, while I was writing this, and came
over, as if expecting me to leash her up.)
The idea that dogs
can pick up mental images from their owners or handlers is also testable! All you’d
have to do is set up the same basic experiment, but instead of having one
handler, the dogs would have two. One—the dog’s primary working partner—would
be given the false information about where the scents were located, but would
have no direct contact with the dog. He or she would be in a control room,
watching the search on a video monitor. Meanwhile the 2nd handler would be
working with the dog, inside the room where the scents were supposedly located.
This person would not be given the false information as to the scents’
locations, just that they were hidden somewhere in the room.
If the dogs still
gave false alerts, it wouldn’t be because of the 2nd handler’s beliefs, or even
because of his or her desires. It would either be inexplicable—a random,
meaningless anomaly—or it would indicate that the dog had some kind of subtle
emotional bond with his primary handler, and was able to pick up information
from him or her about the false locations without needing to be in the same
room with that person.
It seems to me that
much of dognitive science is hobbled by the predicate beliefs that nature is
random and that animals learn through trial and error. There is nothing random
about a dog’s behavior. Yes, they read our micro-expressions, and our body
language, and are perhaps even able to cue-in to changes in our breathing
(which is what may have happened with the dog who just came over, expecting a
walk.) But more than that, dogs feel what we feel. They are always tuned-in to
our emotions.
This is something
every dog lover knows. And I think it’s deserving of scientific inquiry.
