Why Do We Love Dogs: The Human-Dog Bond

Some dogs live to please, others we live to please, but either way it’s clearly a match made in heaven.

We all experience different relationships with our dogs, and while every dog and owner are different, every dog lover can relate to the heart tug of a unique and powerful bond between dog and human-kind.

But how did our two species fall for each other, and why? 

Beginning of the Human-Dog Bond

Although scientists and archaeologists still debate when and where domestic dogs evolved from the gray wolf, most everyone agrees on this: Dogs — our first domesticated animal — formed a close bond with humans about 14,000 to 17,000 years ago.

Some experts theorize early hunters initiated the relationship when they toted home and raised orphaned, too-cute-to-resist wolf pups. Others think bolder wolves made the first advances by hanging around habitations to scavenge leftovers.

After researching the biological basis of the human-animal bond for 16 years, Meg Daley Olmert of Wittman, Md., author of “Made for Each Other, The Biology of the Human-Animal Bond” (Da Capo Press, 2009), believes it was woman who first felt the overpowering urge to take care of a crying wolf pup. “This friendly contact could have kick-started a potent oxytocin hormone feedback system that tamed wolves and charmed humans into keeping them close and feeding them,” she says.

According to Olmert, oxytocin, a hormone found in mammals, suppresses the fear response and lowers blood pressure, heart rate, and stress hormone levels. Also know as the “cuddle chemical,” oxytocin is a hormone produced in the brain to foster bonding between mothers and their young and is associated with bonding, nurturing and attachment.

“Oxytocin has been proven to promote social recognition — like between mother and child — and create a broader sense of relatedness within and between species,” she says. “This is how wolves and humans came to see one another as best friends.”

In any case, these tamer wolves would have made useful sentries and perhaps hunting partners in exchange for food and security. “Initially, I think what we got out of wolves was the companionship of a good night’s sleep!” Olmert says. With their trusty dogs on the lookout for predators or enemies, our early ancestors probably experienced some peaceful rest.

It would have taken only 100 to 150 years to produce domesticated dogs, once people started aggressively selecting for tamer wolves around their villages, says Alan Beck, professor at Purdue University in West Lafayette, Ind., and director of its Center for the Human-Animal Bond. “The breeds initially reflected special roles that early people had for dogs, such as pulling, guarding, and herding,” he says.

Dogs also served, as they do now, as mankind’s best friend. Exactly when dogs transitioned from useful animals to companions we might never know. And for much of history, working dogs certainly outnumbered pets. According to Stanley Coren, Ph.D., a psychology professor at the University of British Columbia, small, companion-only canines also usually belonged to privileged people, like Frederick the Great of Prussia (1712-1786), who apparently had a wing of his palace designated for his Italian Greyhounds.

Today, though many dogs still work for a living, most occupy a companion role in the United States. In fact, an ever increasing number of citizens consider — and adore — their pets as family. Another nice change from the old days: You don’t have to be royalty to keep a dog simply for love

Too Much Love?

You dote on your dog, take him everywhere, shower him with toys and bling, and rave about his fetching qualities. Has your love gone overboard?

Not unless it starts to interfere with other human relationships, your normal day-to-day functioning, your finances, or your pet’s health, says psychologist Stanley Coren, Ph.D. “Lots of high-profile people have had an extraordinary fondness for their dogs and functioned quite normally, like General George Patton and President Lyndon Johnson,” he says.

Why Do I Love My Dog So Much? 

The explanation for why we love dogs is more complex. Let us count some of the ways.

Science: In addition to Olmert’s research, a recent study of the human and dog bond, showed that oxytocin was produced in dogs and humans when they looked into each other’s eyes.  Japanese researchers found that dogs who gazed at their owners for long periods of time had elevated levels of oxytocin, as did the the owner’s levels who were recipients of these loving stares. The study went on to explain that prolonged gaze between owner and dog can create deep bonds similar to those created between parent and child. 

Companionship: We made dogs into our best friends. Humans created dogs to be companions, Coren says. “We’ve been systematically modifying them for at least 14,000 years, and in such a way that they’ve become better companions to us than just about any other creature except another human being.”

Communication: Dogs respond to our emotions and body language. Part of what makes dogs such easy-to-love pals involves how well they respond to us and understand our gestures. For example, recent studies indicate that if you point at something, your dog will look to where you point; a wolf will only stare at your hand. “We’ve bred companion dogs to be empathic,” Coren says. “They can read our moods and subtle aspects of our body language, which is why some people think dogs have ESP.”

Looks: Dogs never grow up. Pedomorphosis, the retention of juvenile characteristics in an adult, is a hallmark of domesticated animals. These juvenile characteristics include physical attributes that automatically make us go ga-ga — think flattened faces and large round eyes — along with behavioral characteristics such as playfulness and reduced aggression.

“Pedomorphic features protect a young animal from the aggressiveness of the parent,” Beck says. “It’s part and parcel of our selection for tameability. You end up with animals locked in a juvenile state, and it triggers positive feelings, so you breed more individuals like that.”

Interaction: We treat dogs like people. Yes, we all talk to our dogs. We also go jogging or play Frisbee with our pets, and caress them — behaviors normally reserved for other humans, Beck says. “But many of these behaviors occur with less risk,” he says. “Dogs never criticize what you say, and they’re almost always happy to be in your company.”

Do Dogs Love Us Back? 

Many recent investigations into the dog’s psyche have shown us that dogs do have the capability to sense and feel many emotions. While dog’s may not feel “love” in the human sense there is no doubt by dog owners, that dogs are capable of showing compassion and understanding to humans and other animals alike. And while dogs may not experience “jealousy” in the human sense they do have reactions and responses that would allow us to believe they are feeling the doggie versions of these things.  

That being said, every dog lover has a story of a time their dog showed them love, compassion or emotions that seems to go beyond what any scientists have been able to nail down.  

For the Love of Dog   

Just as various relationships exist between people, we modern humans have different ways of relating to our dogs. Compare the “Hey, it’s just a dog” person to the “Oh, my sweet baby-kins!” individual.

How people relate to their canine friends depends greatly on where they happen to be in their lifetime, Coren notes. The dogs of our childhood often serve as substitute siblings or playmates. As adults, we may see our pets as exercise buddies, playmates for our kids, or beloved surrogate children. In our golden years, pets are often steadfast friends guarding us against loneliness. “For older individuals, this relationship is quite important, because older people tend to become more isolated,” Coren says. “Dogs give us this wonderful feeling that we’re not alone.”
