"The Genius of Dogs" Book Review




I had a birthday recently. One more year to Freedom 55. Not that realistic – it’ll be more like Freedom 65, or 75, but it doesn’t matter because I love what I do: Working with dogs, reading and writing about dogs. Hence, I was delighted to find Brian Hare and Vanessa Woods’ book “The Genius of Dogs” in the parcel our daughter sent me.

Brian Hare, Ph.D., is an Evolutionary Anthropologist and Associate Professor at the Duke Institute for Brain Sciences, and interested in apes – the human and hairier kind, but also dogs. You can check www.dukedogs.com to find out more. Vanessa Woods is an Australian scientist and journalist, and Brian Hare’s wife.

I loved the book. Loved it for its conversational tone that makes the information accessible to everyone. No science degree needed to comprehend the material.
I love the subject matter. In a nutshell: How dogs are smart; How they compare cognitively and emotionally to infants and young children; How they rely so much on humans for information. How humans and dogs work, and more importantly how we work together – the psychological convergence between us.
Like many other books about dogs, this one has a chapter on domestication, and also like many others talks about Belyaev’s foxes. I almost skipped that section exactly because I had read about it several times before, but am glad I didn’t, because Brian Hare tells the story with fascinating history attached, for example that Stalin declared geneticists enemies of the state. Our present Canadian government labels our environmental scientists and activists enemies of the state. How is your evolution coming along? Eh?
Back to dogs, or more accurately foxes. There’s a photo of one of the domesticated ones in the book I've never seen in any other dog book, and I promise you'll fall in love with the cuteness.
In the context of domestication, Brian Hare elaborates on aggression and kennel club breeding practices that, for the last 150 years or so, select for appearance more than function and temperament. Breeders fail to breed against aggression in favour of a uniformed look, and that might need a mental shift if we want peaceful dogs in our midst in the future.
And the public needs to be educated what to look for, and where, when they dog shop. At the end of the book the authors make a statement I so agree with: Good breeders don’t sell to pet stores, brokers, or online.

Although "The Genius of Dogs" is not a training manual, it talks about methods including behaviorism. Much of what it says plays into Alfie Kohn’s “Punished by Rewards”, with the difference that Kohn’s book  refers to humans, and Hare/Woods of course include dogs.
One of the issues they have with the Skinnerian model to influence behavior is that it always relies on deprivation, which I believe can negatively affect the relationship. I have given this a lot of thought lately and am not at all done thinking yet.
About the clicker the authors say: “At least for the moment, there is no scientific evidence to support the theory that clicker training facilitates faster learning in dogs”. A controversial statement for sure, and they concede that a clicker might make layowners better trainers and could have value in that.
I don’t use a clicker, so that preliminary evidence vindicates what I was thinking all along: Dogs have a natural connection with humans, pay attention, watch for and are receptive to verbal and gestural information, and that was and is always my primary method in relating with and teaching a dog – with the clicker being an option for certain dogs/people, and particular things I want to accomplish.

Brian Hare is a scientist and the book is peppered with studies that back the statements he makes. Studies he and his associates conducted, but also studies done elsewhere, for example at the Eötvös Lorand University in Budapest, Hungary, and you can find out more about that at www.familydogproject.elte.hu.
Perhaps Adam Miklosi rings a bell, and Vilmos Csanyi who wrote the book “If Dogs Could Talk” a few years ago, which I also liked a lot.

I think that we will continue to see studies that reveal how special dogs are - amazing really in their abilities and relationships they form with humans. My hope is that with that people increasingly will steer away from trainers who use the outdated wolf model to justify their forceful and punitive ways. But perhaps also the purely mechanical, operant conditioning method might be adjusted to less of a cookie-cutter, and more of an individual approach.
The end of June, there'll be a conference outside of Seattle I was seriously thinking of attending, but I live on the other ocean, and in Canada at that, and although it is not completely out of my mind yet – alone the road trip from Abbotsford/BC to Redmond/Washington is tempting - for now I’ve signed up for the life stream. I will keep you in the loop.


Coincidentally, a friend and I discussed all that recently, and before I had read “The Genius of Dogs”, on the way to a trainers’ dinner. She wondered what dog training might look like in a decade from now, and I am wondering that too, but feel quite excited about the journey. 

The book came with a birthday card in which my daughter wrote that I already know everything about dogs. She is wrong there: I possibly will never know all there is to know about dogs. Learning never stops. New studies will reveal new insights, and I also believe that like us, dogs are still evolving – evolving with us.

The Smartest Dogs



Will is probably the smartest pooch that ever crossed our doorstep. I admit that I am bias, but there are so many actions I witnessed her do, too many to line up in this post, that confirm to me that she is special. Once, at the dog park, her buddy Kiwi had a stick she badly wanted. Kiwi was still a pup then, weaker and submissive, but nevertheless Will heeded the golden rule that possession equals ownership and did not force it from her. Instead, she walked a few feet away and sniffed the ground so intensely that Kiwi joined in, dropping the stick in the process, which Will instantly ran to and snatched. Another time she took ingenuity a step further: swimming side by side with another dog, she raised her paw and dunked his head under water to make him release the stick he was retrieving back to shore. Again, she grabbed it the moment her friend let go of it, swam to shore and placed it right in front of my feet – grinning I swear.
In my line of work I frequently hear tales of canine tricksters that hoodwink to get what they want. A common one is the pooch barking out the window at nothing to entice his canine cohabitant off the sofa, so he can hog the cushiest spot himself. Anecdotal evidence regarded with skepticism by science purists, but I believe because I meet many dogs with exceptionally connected brain cells – and lately more often than I used to.
It appears that dogs are smarter these days, and not just the intelligent poodles, collies and shepherds. Pure-blooded ones of all breeds, and mutts, are in Dr. Phil’s words plugged in. They are attentive, coiled for action, and learn in a flash. Perhaps, I pondered, this is an evolutionary result of humans beginning to perceive dogs differently? Not like brawny, status-challenging predators, but more… here it goes, what heresy, anthropomorphically?
What shouldn’t surprise anybody is that the smarted dogs have smart owners who understand and take an interest in their dog, and invest the time and effort it takes to achieve whatever they’re aiming for. Think about David Hartwig and his amazing Australian Cattle Dog Skidboot. Labeled by his previous owner as a problem, David saw the potential in the handsome heeler and took trick training to the 11th degree. As amazing as their acts were, Skidboot was also David’s steady companion and working partner.
And there is Bama, a search and rescue trained Labrador retriever who demonstrated incredible self-thinking. I first read about Bama in 2008, in the Fall issue of Animal Behavior. The article by Gary Wilkes discussed false positives in tracking dogs, which is when the dog indicates without actually having found anybody - fibbing so to say. That is more common than one might think, because dogs are reinforced when they locate a lost person, and if that takes too long during a difficult search they can become frustrated and signal anyway to elicit the beloved ball, or whatever else their reward is for a job done as expected. Of course, false positives are undesired. In life or death search operations the dog has to be reliable. Bama’s owner, Theresa McPherson, had a brilliant idea how to solve that problem, and it involved teaching her a new "word".
Bama already knew two signals to discriminate between having found the person alive or dead. Alive was a bark, and someone dead she marked with a quiet lay down by her handler’s feet. The new signal she was about to learn was to touch a stick on her owner’s belt to indicate that she hadn’t found anybody yet, and for which she was also rewarded. That allowed Bama to return frequently to McPherson and inform her on the status of the search, and because she was reinforced for reporting correctly, and not just for finding someone, the frustration stopped and with it the false positives.
Bama’s own brilliance became evident when, during a training exercise, she was confronted with a dilemma. Her task was to locate the scent of a dead person that was planted in a building. Bama obligingly searched, found and returned, but then apparently made a profound mistake. She lay by McPherson’s feet and barked, conflictingly telling her that she found someone who's dead and alive. Naturally, that is impossible and had McPherson puzzled, but she followed her dog to the building anyway and, through an open window, heard people talking outside. The clever Lab, when she found the dead person’s scent, obviously heard or smelled the alive humans too and accurately informed her owner that she found the dead one, but also alive ones. Reporting correctly required that she combined two separate signals into a compound word – and that’s remarkable.
The newest member of the “gifted canine club” has got to be Chaser, and if you google “Border Collie Chaser” you find a whole bunch of articles and video clips. The gist of it is that Chaser comprehends 1,022 proper nouns and 3 verbs. No kidding, and verified that it is not a Clever Hans type hoax. Chaser’s human, 82-year-old retired psychologist John W. Pilley, accomplished that by showing her an object and repeating the name up to 40 times. During daily sessions the collie learned 1-2 new words, and recapped the already known ones. Aside from the unbelievable vocabulary Chaser accumulated, how Pilley taught caught my attention.
The continuous repetition of commands, both in the learning phase and after a dog connects a certain word with a behavior or object, is a big no-no with the dog-training crowd. Immediate, one-command obedience is the mantra, and command repetition during the exercise almost blasphemous. But maybe we need to rethink that, now that Pilley demonstrated that this is exactly the way to teach a dog to comprehend many, many words.
Talking with your dog is okay? More than that, essential if you want a really smart pooch? I am strongly leaning toward it. Not ceaseless chatter; not flooding with non-stop and meaningless acoustic sound, but teaching precise verbal information the dog can use as tools to succeed; words humans use and you need to repeat patiently until the dog gets it. How many repetitions it takes depends on the dog. 40 with Chaser the Border collie; likely a few more if you own a beagle or Saint Bernard.
I never counted how many words my dogs comprehend, and never scientifically tested if they, indeed, understand the spoken word or are just excellent readers of my micro-expressions. But I am certain their intelligence goes beyond prompted actions. I believe that to be true for all dogs. If they were but cute stimulus-response machines, many of us wouldn’t love them the way we do. And if we recognize and foster cognizance some, like Bama who created a new word, and Chaser who is able to pick out an unknown object by distinguishing it from all the familiar ones, leap to a level science is just beginning to explore.
