Note from Con Slobodchikoff: This is a guest post by Dr. Stanley Coren.
Dr. Stanley Coren is
professor of psychology at the University of British Columbia and author of many
books on dog behaviour, including The Intelligence of Dogs, How
to Speak Dog, How Dogs Think, The Pawprints of History, Why We Love the Dogs We
Do, and a children’s book, Why Do
Dogs Have Wet Noses? which won the Best
Children’s Book award from the Animal Behavior Society. His website is

Just as everyone wants to have
smart kids, most people want to own clever dogs. However whether a dog is
“smart” or “dumb” depends upon the specific aspects of its behavior we
consider. For example, was Nobel Prize-winning physicist Albert Einstein
intelligent? Obviously, to derive the theory of relativity required a
mathematical genius. Yet Einstein was so bad at simple arithmetic that his
checkbook was always out of balance.
Intelligence has a variety of
different dimensions. In human beings we might subdivide intelligence into
verbal ability, numerical ability, logical reasoning, memory, and so forth. The
intelligence of dogs also has several different aspects, among which we
recognize three major dimensions. The first is called instinctive intelligence. This really refers to what a dog was bred
for. For example, herding dogs were bred to herd animals. Their ability to
round up animals, keep them close together, and drive them in a particular
direction is inborn and only requires human intervention to keep it under
control and to give it a bit of direction.
Different breeds obviously have
different types of instinctive intelligence. Guard dogs watch over things,
retrievers fetch, hounds track or pursue, pointers sniff out birds and indicate
their location by pointing, while companion dogs are attuned to human social
signals and respond to our moods to provide comfort. Every dog has an
instinctive intelligence, but it is senseless to make comparisons across breeds
as to which are “smarter” in this respect—their abilities are simply too
different to compare.
The second dimension of dog
intelligence is adaptive intelligence.
This is basically a measure of what a dog can learn to do for himself. It
includes learning and benefiting from experience with his environment, solving
new problems, and so forth. Adaptive intelligence can differ among individuals
of the same breed. Thus, all Golden Retrievers have the same instinctive intelligence,
yet while most are quite clever you will occasionally encounter one that seems
totally clueless and makes the same mistakes over and over again. The
difference between the various Goldens is a matter of difference in adaptive
intelligence, and this can be measured by using the appropriate tests.
When most people think of dog
intelligence they often think of the dog working his way through complex
obedience exercises in an obedience ring or on a stage. They might also think
of highly trained animals such as police dogs, guide dogs for the blind,
hearing assistance dogs, or search and rescue dogs. A dog responding
appropriately to his master’s commands and signals tends to give us the
impression that we are viewing the peak of dog intelligence. Thus when a dog
demonstrates through his response that he understands what particular commands
from a human mean, he is demonstrating one of the most important aspects of his
intelligence. It is important because if dogs did not respond to human
instruction, they would not be capable of performing the utilitarian tasks that
we originally valued them for, which means that they would never have been
domesticated and wouldn’t be with us now. This third type of intelligence in
dogs is appropriately called working and
obedience intelligence. It is the closest to what we might call
school-learning ability, and is based upon what the dog can learn to do when
instructed by humans.
It should be possible to actually
rank dog breeds in terms of their working and obedience intelligence. Using
statistics from kennel club records based upon obedience competition trial
results doesn’t work, because it gets mixed up with popularity. For example, in
one recent year, according to American Kennel Club (AKC)
trial records, Otterhounds earned no obedience degrees while Golden Retrievers
earned 1,284. This doesn’t tell us that Otterhounds are stupid, however; there
were approximately 670,000 Golden Retrievers registered with the AKC, while in that same year there were only 300
Otterhounds. Even if Otterhounds were the most brilliant of all dogs, and if
every single one of them earned an obedience degree in the test year, that
would amount to only 300 obedience degrees as compared to the 1,284 degrees for
Golden Retrievers.
While their records can’t help us
assess dog intelligence, the kennel clubs do provide us with another resource,
namely the dog obedience judges themselves. These individuals are trained to
observe and evaluate how dogs perform under controlled conditions. It is not unusual
for a judge to spend 12 to 20 hours on any given weekend judging and scoring
dogs of various breeds. In addition, most judges are also dog trainers,
spending many more hours observing and working with dogs. Because of this
extensive experience watching and evaluating dogs, if any one group of people
should have the accumulated knowledge of the relative performances of various
breeds, it is them. They see each dog perform under the same conditions, and
should be able to separate out the quality of the performance from the number
of competitors.
For my book The Intelligence of Dogs (Free Press, 1994), I contacted all of the
dog obedience judges registered with the AKC and the Canadian Kennel Club, and provided them with a long questionnaire that
allowed them to rank the various breeds in their working and obedience
abilities. Despite its length, 199 judges provided complete information, which
is approximately half of all the obedience judges listed in North
America. If we limit ourselves to breeds for which at least 100
judges provided assessments we end up with a ranking of 133 breeds. This is
shown in the sidebar where dogs are ranked from a high of 1 to a low of 79 in
terms of their obedience and working intelligence. Dogs that share the same
rank number were tied with identical scores. You will note that in the middle
(around average obedience intelligence levels) there are a number of tied
ranks, which is what you would expect if there are some notably bright and some
notably less brilliant breeds, with the vast majority of breeds coming in
around average.
The degree of agreement among the
judges was amazingly high, suggesting that there were real observable
differences that were being reliably detected. For example, when we consider
the dogs ranked highest in obedience or working intelligence, we find that 190
of the 199 judges ranked the Border Collie in the top 10! There was somewhat
less agreement as to which breeds showed the poorest working or obedience
intelligence, yet even here the degree of agreement was still high among my
sample of experts. Of the 199 judges, 121 ranked the Afghan Hound in the bottom
10.
According to the judges rankings the
top 10 dogs in terms of working and obedience intelligence are, in order:
Border Collie
Poodle
German Shepherd
Dog
Golden Retriever
Doberman Pinscher
Shetland Sheepdog
Labrador
Retriever
Papillon
Rottweiler
Australian Cattle
Dog
While the bottom
10 dog breeds (moving downwards) are:
Basset Hound
Mastiff
Beagle
Pekingese
Bloodhound
Borzoi
Chow Chow
Bulldog
Basenji
Afghan Hound
Does this mean that everyone should
rush out and get one of the top 10 breeds of dogs? Definitely not! While a
smart dog will learn everything that you want it to know, it will also learn
everything that it can get away with. This means you may have to spend much
more time “civilizing” your clever dog so that it learns the limits of
behaviour in your household.
Does this mean that we should stop
breeding the dogs low in the rankings to “improve the species”? Definitely not!
Every dog has an instinctive intelligence for which it was bred. Thus the
Afghan Hound, at the bottom of the list, was bred to spot, pursue and pull down
antelope and gazelle. If you ever saw one of them running you would appreciate
how refined that skill is. Also most dogs in our urban society were chosen as
companions—did you take the time to give an intelligence test to the last
person that you were considering as a possible spouse, lover or companion?
In addition, some of the dogs lower
in the intelligence list have other qualities. The Afghan Hound is arguably
among the most beautiful of dogs. I notice that every year People magazine has a special issue presenting “The 50 Most
Beautiful People in the World.” I don’t ever remember People ever having an issue featuring “The 50 Most Intelligent
People in the World.” Just think about what we consider to be the most
important aspects of humans—well, the same applies to dogs!
