Does My Dog Really Love Me? Scientific Research Says Yes!

When my Old English Sheepdog, Miracle, gazes at me adoringly, and I feel a rush of love. I wondered if dogs love us back in the same way?

Do Dogs Feel Love?

When my Old English Sheepdog, Miracle, gazes at me adoringly, I feel a rush of love sweep over me as I pat her head and tell her that she's my “baby girl” and the “best doggie girl ever.” But does she feel the same love for me that I feel for her?

Most dog lovers will tell you emphatically and without hesitation that of course their dog loves them back. However, many behaviorists have argued for years that the dog behaviors that we interpret as love are really just ploys to get rewards or attention.

But there's good news. Recent scientific studies provide evidence that there is indeed reciprocal love between dogs and their owners.

Proof in fMRI Studies

Gregory Berns, a professor of neuroeconomics at Emory University, spent two years training dogs to go into an fMRI scanner in order to find out how their brains work, and especially what they think of humans.

Berns had lost his 14-year-old Pug, Newton, and after a long period of mourning, he wondered if Newton ever felt the same attachment. Since Berns had used fMRI technology to study the human brain for 20 years, he decided that he could use the same science to learn more about the canine brain.

He started the Dog Project, a study in which dogs would be treated as children. Great care was taken to assure that only willing participants would be selected, and that their owners understood any risks involved (although they were minimal). Dogs would be allowed to enter and leave the fMRI device at will.

Berns used his own dog, Callie, as the first test subject. Callie, a shelter-rescued rat terrier, was a fast learner. Remarkably, she was taught to willingly and enthusiastically go into an fMRI simulator, place her head into a chin rest and stay completely still for up to 30-second time periods. Since fMRIs are noisy devices, Callie was also taught to wear earmuffs so that her hearing was protected.

McKenzie, a Border Collie, was the next test subject. Word got out about the study, and within a year the number of canine participants grew to 15. It seemed as if dog owners were anxious to find out what their pets thought about them.

Dogs and humans share many of the same basic brain structures that function identically, a phenomenon known as a functional homology. The main section of the brain that Berns studied was the caudate nucleus, the dopamine-rich part of the brain that plays a key role in the anticipation of pleasure in both humans and dogs. In humans, the caudate activity spikes when we anticipate things we will enjoy, like food or love. The same spike in activity happened to the dogs in the study. The canine subjects' caudate regions lit up in anticipation of food, but more importantly, the region lit up when their owners returned after a brief separation. In fact, Callie's response to the smell of Berns's sweat on a cotton pad was almost identical to human subjects when shown pictures of people they loved.

These findings led Berns to conclude that dogs could experience an emotional life similar to a two-and-a-half-year-old child. They love us and miss us when we're gone. As to the question “Do our animals mourn us when we die?” Berns feels that even with his fMRI technology it would be hard to determine this since it's still not known which part of the brain is activated when humans feel grief.

Berns feels that his findings could have important implications concerning the way that dogs are treated. Since they have feelings that similar to humans, he believes they should be treated more humanely. He makes a great case for this in his New York Times op-ed, "Dogs Are People Too."

Chemical Proof

An important hormone that humans and dogs have in common is oxytocin, often called the “feel good” hormone and the “molecule of love.” Associated with love, trust, and other pleasurable feelings, oxytocin is increased when you are touched by a loved one.

Recent scientific evidence has shown that just the loving gaze of your dog can increase your oxytocin levels. In a study of 55 dogs and their owners, Miho Nagasawa, a researcher at Azabu University in Japan, found that people whose dogs gazed at them for two minutes or longer showed a higher increase of oxytocin than those whose dogs gazed at them for a shorter period of time. Imagine that—the “look of love” from your pooch can instantly make you feel better! But does this human/dog interaction make your pet feel better as well?

The answer is a resounding “yes. Another study conducted by Johannes Odendaal and his colleagues at the University of Pretoria in South Africa demonstrated that there is a reciprocal rise in oxytocin when pets and their owners interact. After having their blood pressure taken and blood samples extracted, subjects were asked to spend half an hour in a quiet room and focus only on their pets. The subjects spent 30 minutes talking to their pets and stroking them. Results showed that the owners' blood pressure decreased and they experienced an increase in oxytocin as well as beta-endorphins (linked to euphoria and pain relief), prolactin (promotes bonding), and dopamine (associated with pleasure). And guess what—as further evidence that dogs really do love their owners, it was found that the pets involved also showed an increase in oxytocin.

The Proof Is in the Yawn

An interesting phenomenon demonstrated by both dogs and humans is contagious yawning. In a social group, when one person yawns, it sets off a reaction whereby others yawn as well. Studies have shown that in humans, contagious yawning is linked to empathy.

The Dognition citizen-science project, conducted in Japan, proved that dogs yawn contagiously when humans yawn, showing that dogs really are in touch with humans. Not surprisingly, the study proved that dogs are much more likely to yawn when their owner yawns. In fact, another study done in Portugal showed that dogs are actually five times more likely to yawn if their owner yawns then if someone else yawns. Karina Silva, the lead researcher of the project claimed that these findings suggest that dogs empathize with humans, and particularly with their owners. So if you want to see if your dog loves you, do the yawn test. I just tried it, and guess what—Miracle yawned immediately!

Final Thoughts

Although most of us dog owners don't really need hard proof that our pets do indeed love us, it's somehow comforting to have the scientific evidence to support our gut feelings. At least there are some facts to fire back at those annoying behaviorists when they say “Your dog only acts like she loves you to gain rewards.” The facts seem to indicate that our dog is indeed feeling the same love for us that we feel for them, that they empathize with us, and are emotionally connected to us. They are indeed our most loyal and best friends

Margaret, I adopted my dog, Cookie from a shelter. She had been abused and abandoned. She has epilepsy and lately has developed gall bladder disease. She is so adorable and loves to come to me and be petted. Despite her health issues she shows so much love. Great article, Margaret, I enjoyed it.

Dressage Husband - interesting about dressage horses being in sync. Thanks so much for reading and commenting!

Margaret Perrottet (author) from San Antonio, FL on May 30, 2015:

MelRootsNWrites - I agree that there is so much more to learn about animals, and I hope that they continue to research the subject. That's so cute that your dog gives hugs. Thanks for stopping by!

Stephen J Parkin from Pine Grove, Nova Scotia, Canada on May 27, 2015:

Not only dogs , but cats and horses too. Our cat even loved the horses and vice versa. Horses have been given the same scan and dressage horses and ridert actually appear to be thinking in sync during rides.

Melody Lassalle from California on May 27, 2015:

Well, it is about time that science figured out what every dog owner already knows. I've always believed that dogs have the ability to love and that they are empathic.

On a side note, I taught my dog to give hugs. I was quite surprised when she started to initiate them herself. No, not the humping thing that some dogs do. It is a gentle embrace with her head lightly on my shoulder. I think there are things we do not know about dogs and are yet to make some wonderful discoveries about their behavior and their connection to humans.

Thanks so much for this thoughtful read this morning!

Brian McDowell from USA on April 13, 2014:

That's probably more an appeasement signal, also known as a calming signal. She probably can read your facial expression and tone of voice to know you are unhappy with her, and she gives that expression to try to calm you down and show she's no threat/challenge to you.

I don't think dogs "know" they are doing something wrong, per se, or at least they don't have any response until there's a consequence, especially for a self-rewarding behavior like taking food off the table or chewing your slippers, etc - and even then, it's best to catch them in the act since after the slippers are chewed and then they see you, they'll likely connect your response to what they are doing at that moment, which might be coming to greet you.

kblover - body language in humans and dogs can certainly express so many things. Experts say that dogs can't feel guilt, and yet from my dog's body language I swear that she looks guilty when she's done something bad.

Brian McDowell from USA on April 12, 2014:

" Most of us, however, are not able to understand a single word any animals says."

Yep - and being verbal creatures, we often forget how to read body language - both of other humans and canines. Sometimes, being able to write and talk can be a curse as well as a blessing. Of course, since dogs "speak" mostly in body language...

Margaret Perrottet (author) from San Antonio, FL on April 12, 2014:

Au fait - I'm sure you're right about dogs mourning the loss of loved ones. I've seen the same thing with dogs that I've had in the past.

So glad you stopped by and read this.

C E Clark from North Texas on April 11, 2014:

Having grown up on a small farm, I know that animals aren't so different from people in that they each have their own unique dispositions, personalities, intelligence, and more.

Scientists may not have proven it yet, but animals do mourn the loss of loved ones, whether those loved ones are other animals like themselves, humans, or friends of a different species.

I remember well how my dog cried when his best friend, a cat, was run over by a car and was dying. I remember how that same dog moped about and was totally forlorn when my mother left him and never came back home to him because she had died.

Animals have been proven to understand a small human vocabulary of 2-300 words but because of the shape of their jaws, etc., they cannot speak our language. Most of us, however, are not able to understand a single word any animals says.

Oxytocin... contagious yawning due to empathy... it's all making sense :-)) This links in so well with the hub I just wrote on animal altruism and intelligence but I dare say you have the scientific edge here! Very interesting, I may have to link from my hub to yours to complement.

Margaret Perrottet (author) from San Antonio, FL on February 10, 2014:

kblover - Amazingly, some studies think that some dogs can understand as many as 160 words, and that their grasp of language is about the same as an average 3 year old. And I'll bet that you're right, that they actually grasp the meaning of what we say to them, even when they don't understand the words themselves. You must see this all of the time as a dog trainer. Thanks so much for stopping by!

"I have always thought that this insistence on associating animal behavior with pure instinct was preposterous, and based mostly on human arrogance that we are somehow on a different level from the other animals."

Great point.

So much of what dog's "can't do" is couched in the implicit "like a human". For example, "dogs don't understand words". Like humans? No, but they can be taught meaning just like if you asked a kid "what's a ball?" they'll get a ball and show you or describe it (taking a mental image and putting it into words), not give you the Webster's definition. Dogs do the same via behavior (grabbing a ball and bringing it to you, recalling a mental/scent image of the object).

Margaret Perrottet (author) from San Antonio, FL on February 09, 2014:

Mel - I never looked at it that way, but you're right - it is arrogant of humans to view animals like that. Thanks for reading and commenting - it's much appreciated.

Mel Carriere from Snowbound and down in Northern Colorado on February 09, 2014:

I have always thought that this insistence on associating animal behavior with pure instinct was preposterous, and based mostly on human arrogance that we are somehow on a different level from the other animals. I am glad you have pointed out this evidence that supports that dogs, and other animals, are not much different from us at all, with the exception that we can walk upright, which gives us a tremendous advantage. Great hub!

Margaret Perrottet (author) from San Antonio, FL on January 30, 2014:

kblover, I agree about the behaviorist standpoint, and I guess the same can be said for humans being programmed to use certain behavior to get attention. It's nice that this study shows that humans and dogs are really quite similar with their emotional lives. So glad you liked this hub, and thanks for taking the time to leave such a great comment!

Brian McDowell from USA on January 29, 2014:

This is awesome. Always nice when science confirms things like this - debunks yet more myths about dogs just being simple emotionless animals that are one step from organic robots with fur.

Great hub and enjoyed reading it. Now excuse me while my dog and I stare and yawn at each other :D I think I have a sweaty sock for him to sniff too :D

From a behaviorist standpoint, it still shouldn't be surprising. Dogs use body language to communicate and express their emotions. Yawning is a social/calming signal at the minimum.

Dogs probably DO use these things to try to solicit care/attention (it's what puppies do, part of their innate "programming" - just like when my dog Wally gets "out of the blue" super affectionate, a seizure might be coming on and he's like "can you help me?" or "I'm scared, daddy!") but it's now we know they also might just want our company instead of a treat or a game. What they might want is some emotional support!

Margaret Perrottet (author) from San Antonio, FL on January 29, 2014:

I wasn't really surprised either - it seems so obvious to anyone who is bonded to their dog that the love goes both ways. However, it's been a long time argument with behaviorists, who insist that their behavior is merely manipulation. Thanks so much for reading and commenting - I really appreciate it.

Christy Kirwan from San Francisco on January 29, 2014:

Can't say I'm surprised, but I'm glad to hear it verified by science! Great Hub. :)

You are most welcome mperrottet.

Margaret Perrottet (author) from San Antonio, FL on January 25, 2014:

mecheshier - I agree with you on both points. All of my pets have had such different and unique personalities. I'm glad you enjoyed this hub, and thanks so much for taking the time to comment and vote.

mecheshier on January 24, 2014:

Fabulous Hub. I was just talking about this with a friend of mine. I feel that All animals have their own personality. And Yes, they can certainly feel and show love.

Thank you for such a well researched post. Voted up for useful and awesome! :-)

Dogs Mentally Understand How Much We Love Them, Canine Cognition Expert Assures

Dr. Brain Hare says that the way your dog stares lovingly is their way of hugging you with their eyes

We recently learned that your dog most likely lovingly dreams of you, so it should be no surprise that you are on their mind almost all of the time.

To get an idea of just how your pup thinks and feels, Dr. Brian Hare has dedicated his life to studying canine cognition and its eccentricities. He has recently teamed up with Purina Pro Plan Bright Mind, a dog food dedicated to improving your pet’s cognitive function, to help owners figure out what’s really going on in their dog’s brain.

To strengthen the bond between humans and their pups even further, Dr. Hare has answered some of the burning canine cognition questions many curious dog lovers have.

Does my dog know how much I love him?

Yes, your dog knows how much you love him! Dogs and humans have a very special relationship, where dogs have actually hijacked the human oxytocin bonding pathway that is normally reserved for our babies. When you stare at your dog, both your oxytocin levels go up, the same as when you pet them and play with them. It makes you both feel good and reinforces your bonding. Does your dog ever stare at you for no reason? They are just “hugging you” with their eyes.

Are dogs known to go through depression like humans?

It is very possible for dogs to become depressed. After 9/11 it was reported that many of the search and rescue dogs were suffering from depression-like symptoms because they could never find any survivors, only bodies. Their handlers would stage “fake” finds so that the dogs would cheer up and keep searching. Additionally, dogs do tend to become attached to their owners and will behave differently when that person is not around. Given their great capacity for empathy, dogs can also respond to their owners’ moods and feelings, like depression.

How many words can a dog actively understand?

This is one of the big recent discoveries in the canine cognition science community. Some dogs can learn “object labels” or words the same way as humans infants. So these dogs are not learning through trial and error or repetition, but learning through inference. They use a strategy called the “principle of exclusion” and, just as with humans, the researchers did not find an upper limit to the number of words these dogs can learn. Dogs are the only species other than humans that have been found to have this ability. Now the question is whether all dogs can do this, or only some.

How much do we know about dogs’ abilities to make decisions? Do dogs problem solve?

Dogs problem solve all of the time, although they all approach and solve problems in their own way. One of the exciting things about cognitive science is that it allows us to examine dogs’ minds, just by observing how they make choices. For instance, if I hide food under one of two cups, then point to the empty cup, a dog that follows my point is a social problem solver — he wants to cooperate with me to solve the problem. But a dog that chooses the cup where they saw me put the food originally is relying on his memories instead.

Is there something you’ve found that owners can do to support their dogs’ brain health and mental well-being?

Dogs are just like us they need a good diet, lots of exercise and mental stimulation. It sounds simple, but doing these three things can really help your dog reach his full potential. Nutrition, in particular, becomes especially important around age 7 when the glucose metabolism in his brain begins to change. I feed my dog Tassie Purina Pro Plan Bright Mind Adult 7+, which contains enhanced botanical oils shown to promote alertness and mental sharpness in dogs seven and older. I also make sure he gets lots of exercise for both his body and mind, with long walks, swimming and playing our Dognition games.

Dog Emotions

As dogs are able to experience affective states, they may be able to express them through emotional cues such as a smile.

Can dogs have emotions?

Firstly, what is a human smile? A smile is the formation of one’s features so that their mouth is turned up with or without their teeth exposed.

In humans, a smile is associated with delightful emotions (i.e. being happy!). However, is this the same for a dog’s smile?

Emotions are formed by the limbic system in the brain which is responsible for a variety of functions such as memory, motivation, behaviour and emotion. This results in either a positive or negative conscious mental state.

It is strongly evident that the mammalian brain differs across species, with the human brain being one of the most well-developed. This is therefore true in comparison to canine species.

For example, a human has a highly developed neocortex in comparison to the dog (the neocortex is an area of the brain which is associated with higher order thinking).

As dogs have a less developed neocortex questions have risen, if dogs are capable of experiencing emotional intelligence.

However, in 2012, scientists at the University of Cambridge concluded that “the lack of the neocortex does not impede a non-human animals’ ability from experiencing emotions (i.e. affective states)”.

The same scientists stated that non-human animals are also “capable of exhibiting intentional behaviours due to the presence of similar neurological structures” in their brains.

So, dogs do smile after-all! But does this mean the same as a human smile?

Yes, your dog really does understand what you say, study suggests

August 30, 2016 / 11:18 AM / AP

BERLIN — Scientists have found evidence to support what many dog owners have long believed: man’s best friend really does understand some of what we’re saying.

Researchers in Hungary scanned the brains of dogs as they were listening to their trainer speaking to determine which parts of the brain they were using.

They found that dogs processed words with the left hemisphere, while intonation was processed with the right hemisphere – just like humans.

What’s more, the dogs only registered that they were being praised if the words and intonation were positive meaningless words spoken in an encouraging voice, or meaningful words in a neutral tone, didn’t have the same effect.

“Dog brains care about both what we say and how we say it,” said lead researcher Attila Andics, a neuroscientist at Eotvos Lorand University in Budapest. “Praise can work as a reward only if both word meaning and intonation match.”

Andics said the findings suggest that the mental ability to process language evolved earlier than previously believed and that what sets humans apart from other species is the invention of words.

“The neural capacities to process words that were thought by many to be uniquely human are actually shared with other species,” he said. “This suggests that the big change that made humans able to start using words was not a big change in neural capacity.”

While other species probably also have the mental ability to understand language like dogs do, their lack of interest in human speech makes it difficult to test, said Andics.

Dogs, on the other hand, have socialized with humans for thousands of years, meaning they are more attentive to what people say to them and how .

The study was published in the journal Science.

Andics also noted that all of the dogs were awake, unrestrained and happy during the tests. “They participated voluntarily,” he said.

Does Your Dog Prefer You Over Anyone Else? It's Complicated.

Whether your pet wants to be around its owner or a stranger depends on the situation, a new study says.

Will Your Dog Pick You Over a Stranger?

Does your dog really want to hang out with you instead of anyone else? We like to think so, but research shows that it's a little more complicated.

Scientists already knew that dogs interact with objects and explore a room more in the presence of their owner than with a stranger. And while you might not have felt you needed academic research to validate this, pets greet their owners longer and more enthusiastically than non-owners after a period of separation.

A new study has shown, though, that how dogs behave with their owners vs. strangers may depend on the context and the task. (Read more about why dogs are so friendly.)

Researchers in Florida gave pet dogs recruited from homes a choice of getting petted by their owner or by a stranger in different situations.

One group was tested with their owner and a stranger in a familiar place: a room in their own home. Another was tested with their owner and a stranger in an unfamiliar place. The dogs were free to do whatever they wanted if they approached, the person petted them for as long as they were close.

The results bring to mind the old real estate cliché: Location, location, location!
