In their recent book “Made to Stick,”
Chip and Dan Heath detail the characteristics that make an idea or
explanation “sticky.” According to their analysis, stories that are
simple, unexpected, and concrete capture our imagination and get lodged
in our brains. Many urban myths, they point out, are ideal examples of
this phenomenon.
This story is simple (pack structure is presumably a clear-cut ranking of alpha, beta and omega animals), unexpected (imagine having the descendent of a wild wolf right in our living rooms!), and concrete (who hasn’t seen TV footage of a wolf pack chasing down a moose or elk?). So sticky is this canine urban myth, in fact, that it refuses to die, despite the series of inaccuracies at its core.
Here are just a few of the inaccuracies embedded in the “dog as domesticated wolf” story.
This version of dog evolution, starring the proto-dog as a scavenger of human waste at village dump sites (think “large rat”), is surely less sexy than proto-dog as noble wolf tamed by clever ancient humans. But it’s essential for our modern view of dog-training because scavenging “village dogs” don’t have a pack structure at all. They don’t hunt cooperatively. Other dogs are competitors, not helpers, in finding edible garbage. And so they live alone or in groups of two or three.
One perfect
example of a “sticky” story is the ever-popular notion that dogs are
essentially domesticated wolves who view their human companions as
members of their hierarchical pack.
This story is simple (pack structure is presumably a clear-cut ranking of alpha, beta and omega animals), unexpected (imagine having the descendent of a wild wolf right in our living rooms!), and concrete (who hasn’t seen TV footage of a wolf pack chasing down a moose or elk?). So sticky is this canine urban myth, in fact, that it refuses to die, despite the series of inaccuracies at its core.
Unfortunately, both dogs and their
owners suffer the consequences of this fable, for it is from this story
that we get the popular but unfounded training decree that humans must
be “alpha” in their mixed-species pack.
Here are just a few of the inaccuracies embedded in the “dog as domesticated wolf” story.
Myth 1: Wild wolves form hierarchical packs in which individuals vie for dominance.
Not
always. And maybe not even very often. It turns out this common
assumption about the social dynamics of wolves is based on studies of
captive animals whose group structure was non-natural (i.e., the wolves
came from various locations and lineages). After a broad review of the
scientific literature and thirteen summers spent observing free-living
wolves on an island in the Northwest Territories in Canada, wolf
ethologist L. David Mech concluded that social interactions among
wolf-pack members are nearly identical to those among members of any
other group of related individuals. In essence, the typical wolf pack is
a family in which parents guide activities of younger members. Vying
for dominance in the pack hierarchy is not a priority. Care-taking and
teaching of younger pack members by adults is.
Myth 2: Dogs, close relatives of wolves, must also form packs in which individuals vie for dominance.
It is true that there is virtually
no difference in the genetic material of dogs and wolves, or of dogs
and coyotes or jackals, for that matter. But, from an ecological
perspective, dogs and wolves are indeed distinct species because they
are adapted to different niches. That is, they earn their livings in
different ways. Wolves kill large prey, while dogs live in partnership
with humans.
Recent research regarding the
evolution of dogs indicates that this partnership did not occur as a
result of our human ancestors’ attempts to tame wild wolves to be guard
animals or hunting companions. It appears much more likely that dogs
evolved from a wolf-like ancestor not through artificial selection by
humans but from a process of natural selection filling a new ecological
niche. That niche was the town dump, which first appeared approximately
15,000 years ago, at the end of the last Ice Age. This is when humans
began creating permanent villages. Wolves found a new food source: they
could forage on the waste products in the refuse piles. The individual
wolves who were able to continue eating even when humans approached were
at a reproductive advantage. In other words, the less skittish wolves,
the “tamer” ones who didn’t flee at the first indication of a nearby
human, ate more. Over many generations, this produced the behavioral
quality that most distinguishes dogs from wolves: dogs will approach
rather than avoid humans.
This version of dog evolution, starring the proto-dog as a scavenger of human waste at village dump sites (think “large rat”), is surely less sexy than proto-dog as noble wolf tamed by clever ancient humans. But it’s essential for our modern view of dog-training because scavenging “village dogs” don’t have a pack structure at all. They don’t hunt cooperatively. Other dogs are competitors, not helpers, in finding edible garbage. And so they live alone or in groups of two or three.
Myth 3: Dogs incorporate humans into their view of pack hierarchies.
Despite
data to the contrary, many people still believe dogs form linear
hierarchies of alpha (dominant) and omega (submissive) individuals. Many
trainers have capitalized on this belief system by arguing that you can
solve behavior problems in your dog only when you have established
yourself as Alpha dog among the pack of creatures in your home (people
and dogs). And so many folks waste time complying with irrelevant rules
(e.g., “always eat your meals before your dogs eat theirs”) when they
instead could be using that time and effort to conduct simple effective
training (e.g., rewarding desired behaviors). Often they also use
physical force, such as shaking the dog by the scruff of the neck,
pinning him on his back, or grabbing his muzzle – all because they’ve
heard these are methods alpha-ranked wolves use to discipline
subordinates.
But
even if dogs did form linear packs, there’s no evidence to suggest that
they perceive humans as part of their species-specific ranking. In
general, humans lack the capability to even recognize, let alone
replicate, the elegant subtleties of canine body language. So it’s hard
to imagine that dogs could perceive us as pack members at all.
Maybe
we need a new sticky story. Dogs are lovable scavengers. Their
evolution has made them dependent on humans to provide food. This
concept of humans as feeders, rather than as “leaders of the pack” forms
the foundation for a logical, reward-based approach to
dog-training. And since even wolves organize themselves into family
units, we can aspire not to be dominant pack leaders, but good “parents”
instead, that is, excellent care-takers and teachers of our dependent
dogs.
