Dogs and humans share one of the strongest bonds between two different
species on Earth. The connection has grown so deep, it’s literally
become coded into our genes. And a wave of new research is shedding more
light on these all-important dog-human relationships and what our furry
friends are thinking. (Why so important? Just consider that 44 percent
of American households have at least one dog.) What we’re finding
out about how we influence each other, and our similarities, is nothing
short of mind-blowing.
Dogs process and respond to things in ways that are similar, scientifically,
to how a child behaves. Dog owners might know this intuitively, but new
research is showing that the things we think we know might only be the
tip of the proverbial iceberg.
Some people see a dog eating grass or chewing on a shoe and think it’s
stupid. That couldn’t be further from the truth.
Dogs, like kids, do things for a reason, even if it seems strange to adults.
For starters, dogs experience the world a lot like kids do who are in
the oral fixation stage -- they want to taste everything. Dogs also experience
anxiety just like humans do, and they might try and cope with it, for
example, by chewing on a shoe (rather than, say, eating a tub of ice cream).
It’s due in no small part to the fact that dogs have many of the
same brain structures and hormones that humans do, a reality about which
we’re only now beginning to find out.
“It all depends on the dog, but, just like people, dogs have their
serious moments and their silly moments,” McGowan says. “[But]
dogs explore the world with their mouths, they might just be exploring
their world and learning more about [it],” by eating grass or chewing
on a shoe.
“There’s a physiological response going on,” adds Brian
Zanghi, Ph.D., a research scientist. “There’s something driving
them to do that.”
Sometimes we’ll make a happy face and our dog perks up. Maybe it’s
because they know exactly what they’re looking at.
Research now tells us that dogs will look us in the eye, track our eye
movements (at the level of a 6-month-old child) and even distinguish between
our emotional expressions. Scientists ran a study with pet dogs in which
they trained them to distinguish between photos of happy and sad faces
using treats, and then mixed up all the photos. They then had the dogs
look at either a section of a happy face (e.g., the eyes) or a section
of a sad face (e.g., the mouth) and found that dogs that learned to recognize
the happy face would respond to it much more quickly than the dogs who
were taught to recognize the sad face. Meaning, they were having an even
greater response to happy faces.
“Dogs probably use their memories of real emotional human faces to
accomplish the task,” the study’s authors explained.
Some people think that their dog looks guilty after peeing on the rug.
It’s not, but the truth is even better.
The mind of an adult dog, researchers believe, is roughly equivalent to
that of a child who's 2 to 2-and-half years old. So, although a dog
won’t develop more complex emotions such as guilt, evidence does
suggest that canines experience joy, fear, anger, disgust and love, in
large part because they have many of those same brain structures and hormones as we do.
“The usual situation is where you come home and your dog starts slinking
around … and you then find that he or she has left a smelly brown
deposit on your kitchen floor,” writes Stanley Coren, Ph.D., F.R.S.C.,
the author of several books on canine cognition. “It is natural
to conclude that the dog was acting in a way that shows that it is feeling
guilty … . However, what you see is his [more basic] fear of punishment.”
