Lately, it seems, hardly a month goes by without either some viral video or paper-writing scientist suggesting that — contrary to what scientists and the media think we think — dogs feel emotions much like our own, or at least a doggy version of them.
If it’s not a video, like the one above – which is being described in the news media as a dog not just feeling remorse, but atoning for his misdeed — it’s a new scientific paper proclaiming, yes, dogs do feel … you name it … joy, fear, anger, guilt, pride, compassion, love, shame.
(If you didn’t already think dogs feel joy, you may not be the world’s most perceptive person.)
(Some, apparently, get so overwhelmed by it that they pass out.)
This month’s emotion? Jealousy.
Dr. Christine Harris, a psychologist at the University of California, San Diego — after a study involving dogs, their owners, stuffed animals, jack-o’-lantern and children’s books – concluded that dogs showed a “primordial” form of jealousy, meaning, I guess, not as evolved, twisted, complex, nasty and, sometimes, fatal as the human form.
According to an article in the New York Times, the dog version of jealousy is “not as complex as the human emotion, but similar in that there is a social triangle and the dog is trying to make sure it, not the rival, receives the attention.”
In the study, as it’s described in a a PLoS One paper co-written by Harris, researchers compared the reactions of dogs when their owners petted and talked to a jack-o’-lantern, read a children’s book aloud, and petted and talked to a stuffed toy dog that barked and whined.
The dogs paid little attention to the jack-o’-lantern or the book. But when dog owners petted and talked to the stuffed dog, their dogs reacted, coming over, pushing their noses into the owner or stuffed dog, sometimes barking, and sniffing the rear end of the stuffed dog.
I’m not sure that’s proof of jealousy — it could just be proof that dogs are smart enough to investigate when humans are trying to dupe them. On top of that, most dogs have experience playing with stuffed toys, as opposed to plastic pumpkins and children’s books. So it’s not too astonishing they would have a more excited reaction to them.
In that way, the findings of this study aren’t really too surprising, or revealing, but they are indicative, I think, of a trend — in the scientific community, in the news media, and among normal members of society — of seeing dogs more and more as humans.
The “dogs feel jealousy” study, for example — flimsy as its findings sound — was picked up by most major news organizations.
“Study: Jealousy Is So Universal Even Dogs Feel It,” reported the New York Times.
“Study: Dogs Can Feel Jealous, Too,” said a CNN headline.
At least NPR phrased their headline as a question: “Does Your Dog Feel Jealous, Or Is That A Purely Human Flaw?”
These days, the news media doesn’t need a legitimate study to draw sweeping conclusions; a viral video will do.
The headlines all presume to know what the beagle is feeling, and some go so far as to explain the goal of his behavior as well: “I’m Sorry! Charlie the guilty dog showers crying baby with gifts to apologize for stealing her toy,” reads the headline in The Daily Mail.
My problem is not with attributing emotions to dogs. I believe they have most of the ones we do, or at least most of the desirable ones. I believe they have other magical gifts and skills we haven’t even begun to figure out. I believe studying what’s going on in their heads is a good thing — at least when it’s done by dog experts. I can even handle a little anthropomorphization; given we’re humans we tend to interpret things in human terms.
What bothers me, for starters, is presenting such findings as new, when dog owners have known most of them all along. Sometimes, it’s as if scientists and the news media are saying, oh wait, we’ve discovered dogs are not unfeeling blobs of fur, after all. Well, duh.
The problem I have is not so much ascribing emotions to dogs as it is the vanity of assuming emotions are something only humans feel.
And feel free as well, video posters, to share your dog’s interesting and seemingly human-like behavior, and to offer any theories you might have.
But let’s not leap to wild conclusions, based on how things look through our human eyes. Let’s not forget that dogs have had emotions all along. Let’s not assume they are “catching up” with us in terms of their emotions and behaviors. Maybe they’ve been ahead of us all along.
And let’s not be so surprised — given the centuries man has been choreographing their evolution, and the half century or so they’ve been mostly living inside with us — that they’re picking up some of our habits, good and bad.
While we’re at it, let’s let dogs remain, at least in part, dogs.
Let’s keep in mind, during all this, what we can learn from them. Are dogs lagging behind us, in terms of developing a sense of jealousy, or are they exhibiting a purer form of what we homo sapiens have taken to ridiculous extremes?
And let’s at least keep our minds open to the possibility that, when it comes to what dog and man can learn from each other, we may not always be the teachers, or the role models, in that equation.

Throw a dog who has never gone swimming into a pool and, pretty much instantly, he’ll start moving his four legs in a series of motions we’ve come to call the dog paddle.
Throw a human who has never gone swimming into a pool and — though the possibilities are much higher for helpless flailing about, cussing, drowning, or becoming traumatized for life — he may eventually come to his senses enough to try and work his way back to the side of the pool. He’ll do so not using a butterfly stroke, breast stroke or Australian crawl, but by doing what dogs do.
The dog paddle: It’s seemingly instinctual. It’s primitive. And though we humans mostly outgrow it, it remains sort of the default mode of propelling ourselves through water.
Just how primitive it may be is under investigation by Dr. Frank Fish, a professor of biology at West Chester University who — maybe because of his name, maybe not — has spent most of his career studying how marine mammals swim.
Most recently, he has been studying the swimming motions of dogs, and he has concluded that they are very similar to the motions dogs use in trotting. That explains the ease with which most dogs can make the transition from land to water — requiring no lessons, and (generally) little coaxing: They basically propel themselves the same way in water as they do on land.
That their stride and strokes are nearly identical is interesting in itself, but Fish thinks it could also help explain how whales and dolphins ended up in the ocean.
Fish subscribes to the theory that marine mammals were intitially four-legged land dwellers who ventured into the water one day (likely dog paddling at first), decided they liked it better there, then evolved into such super swimmers that they no longer needed legs, or, for that matter, land.
He borrowed a swimming pool used to rehabilitate horses at the University of Pennsylvania.
Analyzing the video, Fish and fellow researchers saw that dogs swim much like they run — with diagonal pairs of legs churning in unison, according to Science Daily. Fish presented his findings at the 2014 Society for Integrative and Comparative Biology (SICB) meeting in Austin.
While there’s plenty of dog research we’d categorize as a silly waste of time, we find all this pretty intriguing.
First, it reminds us that practice makes perfect — to think that long, long ago there might have been a couple of four-legged dolphins who didn’t know how to swim, hesitating at the edge of the water: “I dunno, it looks dangerous … should we go in?”
Second, in an era when we’re increasingly relying on computers to do our thinking for us, it serves as a warning that those muscles we don’t use can disappear. It raises a host of interesting questions about our future, and our past.
Why is it we humans tend to dog paddle in our first encounters with water? Is that some sort of instinctual nod to a past when we got about on four legs, instead of two?
If cavemen had spent more time at the swimming hole, might we homo sapiens have evolved into something more amphibious?
Given that, might mermaids really exist?
It’s kind of inspiring to think there might have been a day when dolphins, the planet’s most graceful swimmers, were total klutzes in the water — that they started off splashing about with some awkward looking dog paddling and progressed to the point where they could actually leap out of the water.
It reminds us that, maybe, anything is possible with enough hard work — even when it comes to behaviors we might think are genetic and therefore unchangeable. Do we sometimes wear our genes too tightly, and allow them to restrict us from leaping into new things, and getting over old ones?
We wish Fish luck in unraveling how four-legged terrestrial forms evolved into no-legged, finned ones. And as long as the dogs involved in his research are having a good time – given Fish is letting his own dog be used in the study, we assume they are – we have no problem with them helping the professor prove his point.
In other words: Go Fish!

With all the research into how the medical issues of dogs often run parallel to our own, it’s no surprise that eight obsessive-compulsive Doberman pinschers are adding to our body of knowledge about that disorder.
A new study made use of MRI brain scans and found dogs and people with obsessive compulsive disorder (OCD) have similar brain abnormalities and share certain brain characteristics.
Three years ago, researchers found the shared gene believed responsible for flank-sucking, blanket-sucking and other compulsive behavior in Dobermans.
The new study shows what’s going on in their brains is similar — at least as an MRI sees it — to what’s going on in our’s.
“We have a lot of commonality with our best friend the dog,” said study leader Niwako Ogata, an assistant professor of animal behavior at Purdue University College of Veterinary Medicine in Indiana.
Just as elderly dogs with the canine equivalent of Alzheimer’s are being used as models to understand the degenerative disease in people, studying dogs is providing some clues into OCD, an anxiety disorder afflicting anywhere from 2 to 8 percent of Americans.
For the study, Ogata and colleagues recruited eight Doberman pinschers with CCD (canine compulsive disorder) and a control group of eight Dobermans without CCD, according to National Geographic. The team obtained MRI scans for each group and discovered that the CCD dogs had higher total brain and gray matter volumes and lower gray matter densities in certain parts of the brain. That’s similar to the structures of people brains’ with OCD.
It’s not known why both species’ brains show these features, Ogata said, but her team plans to repeat the experiment with more dogs and more breeds.
The team chose Dobermans because of the prevalence of CCD in the breed. About 28 percent of Dobermans in the U.S. are afflicted.
People with OCD often perform the same rituals over and over again, like washing and rewashing their hands and locking and relocking doors. In dogs, common compulsive behaviors include paw-licking and tail-chasing.
Ogata, whose study was published online in April in the journal Progress in Neuro-Psychopharmacology & Biological Psychiatry, said the study provides a better idea of “”how brains develop, and when and how genes interact with [their] environment to cause some behavior problems for both humans and dogs.”

A new study suggests the earliest domestic dogs weren’t just kept for hunting and protection, but for loving — a premise supported by evidence that some prehistoric pet owners actually outfitted their dogs in bling, if not before death, at least after it.
An analysis of ancient dog burials, published in PLoS ONE, found that deceased dogs were often laid to rest not just with respect, but with toys and ornaments, Jennifer Viegas reports on Discovery.com.
The findings show that, at least as recently as 10,000 years ago, dogs were valued for more than their ability to stand sentry and track game.
The researchers also say the earliest dog lovers were fish-eaters, and held spiritual beliefs. Subsisting on diets rich in seafood, they apparently didn’t rely on dogs to help them find dinner, or as dinner.
“Dog burials appear to be more common in areas where diets were rich in aquatic foods because these same areas also appear to have had the densest human populations and the most cemeteries,” Robert Losey, lead author of the study told Discovery News.
“If the practice of burying dogs was solely related to their importance in procuring terrestrial game, we would expect to see them in the Early Holocene (around 9,000 years ago), when human subsistence practices were focused on these animals,” Losey, a University of Alberta anthropologist, added. “Further, we would expect to see them in later periods in areas where fish were never really major components of the diet and deer were the primary focus, but they are rare or absent in these regions.”
For the study, Losey’s team researched dog burials worldwide, but focused particularly on ones located in Eastern Siberia. The earliest known domesticated dog was found there, dating to 33,000 years ago. Dog burials in the region are more recent, going back about 10,000 years.
They found that dogs were sometimes buried with meaningful items, sometimes even their human, showing that man’s bond with dog — while it may be ever-strengthening — goes way, way back.
According to the Discovery report:
“…One dog, for example, was laid to rest “much like it is sleeping.” A man was buried with two dogs, one carefully placed to the left of his body, and the other to the right. A dog was buried with a round pebble, possibly a toy or meaningful symbol, placed in its mouth. Still other dogs were buried with ornaments and implements, such as spoons and stone knives.
“One of the most interesting burials contains a dog wearing a necklace made out of four red deer tooth pendants. Such necklaces appear to have been a fashion and/or symbolic trend at the time, since people wore them too.”
The researchers found that most of the dog burials in the area occurred during the Early Neolithic era, about 8,000 years ago.

In a collaboration between Penn and the Monell Chemical Sciences Centers, Ohlin and McBain (above) and Thunder (left) will use their noses to detect the disease in humans.
Ovarian cancer kills more than 14,000 women every year and is the fifth leading cause of cancer-related deaths in women in the nation.
The collaboration, the Philadelphia Inquirer reports, takes aim at the silent killer with a combination of chemistry, nanotechnology — and dogs.
Canines have been detecting lung and breast cancer for years. With an $80,000 grant from the Kaleidoscope of Hope Foundation, the new project will assess their effectiveness in sniffing out ovarian cancer, and continue an investigation that has been underway in Sweden.
The Swedish professor behind that project, who was using his own dogs for the study, is retiring. But he’s lending his expertise to those involved in the Penn project.
“He’s been advising us along the way to we don’t repeat the same mistakes he made along the way,” said Dr. Cynthia Otto, director of the Working Dog Center and Associate Professor of Critical Care at Penn Vet.
While the disease is often difficult to diagnose, ovarian cancer’s victims have a survival rate of 90 percent. No effective screening protocol yet exists to detect cases in the early stages.
In the new program, scientists from Penn Medicine’s Division of Gynecologic Oncology will take tissue and blood samples from both healthy and ovarian cancer patients. The samples will be analyzed by chemists, scientists, computers and the puppies at the Working Dog Center, who will be exposed to healthy samples and cancer samples in vented containers they can’t access, but can smell.
The dogs began their training at 8-weeks of age.
“They’re all fabulous and they are very strong in olfaction,” Otto said.

Cats displaced dogs as the nation’s favorite pet – or favourite, if you live there – for the first time in 1994, according to the Pet Food Manufacturers’ Association (PFMA).
Now, a study by the association predicts dogs will be number one again, possibly as early as this year.
“Rovertaken,” read the headline in the Sun. “It’s raining more dog than cat,” said the Daily Mail.
The study says the number of dogs in Britain is at an all-time high having risen from 5 million in 1970 to 8.3 million today. Cats have fallen from a 2004 peak of 9.6 million to 8.6 million.
Figures from the Kennel Club reveal ‘handbag dog’ breeds have increased sixfold and the number of Chihuahuas have tripled since 2001.
While more households have dogs than cats — both in the U.S. and Britain — there are more cats overall in both countries, given the number of households where mutliple cats reside. As of 2007, census figures showed 82 million cats and 72 million dogs in the U.S.

A University of Maine graduate student says he has found a bone fragment from what he believes is the earliest domesticated dog ever found in the Americas — one that walked the continent 9,400 years ago.
And where he found it — ensconced in a dried-out sample of human waste — gives proof that eating dog was part of America’s culture, at least before America was America.
Graduate student Samuel Belknap III came across the fragment while analyzing a sample of human waste unearthed in the 1970s. Carbon-dating placed the age of the bone at 9,400 years, and a DNA analysis confirmed it came from a dog — as opposed to a wolf, coyote or fox.
The Associated Press reports that the fragment — which was the dark orange color characteristic of bone that has passed through the digestive track — was found in Hinds Cave in southwest Texas.
The fragment provides the earliest evidence that dogs were eaten by humans in North America, and may have been bred as a food source, he said.
Belknap was studying the diet and nutrition of the people in the Lower Pecos region of Texas between 1,000 and 10,000 years ago when he came across the bone.
Belknap and other researchers from the University of Maine and the University of Oklahoma’s molecular anthropology laboratories, where the DNA analysis was done, have written a paper on their findings, scheduled for publication in the American Journal of Physical Anthropology later this year.
The fragment is about six-tenths of an inch long and three- to four-tenths of an inch wide. Belknap said he and a fellow student identified the bone as a fragment from where the skull connects with the spine. He said it came from a dog that probably resembled the small short-haired dogs that were common among the Indians of the Great Plains.
Other archaeological findings have found evidence of domestic dogs in the U.S. as long as 8,000 years ago.
A 1980s study reported dog bones found at Danger Cave, Utah, were between 9,000 and 10,000 years old, but those dates were based on an analysis of the surrounding rock laters as opposed to carbon dating. In Idaho, researchers believed they’d found 11,000-year-old dog bones, but later tests showed them to be no more than 3,000 years old.
Worldwide, studies have found evidence of dogs going back 31,000 years from a site in Belgium, 26,000 years in the Czech Republic and 15,000 years in Siberia.
The earliest dogs in North America are believed to have come with the early settlers across the Bering land bridge from Asia.
Belknap said eating dogs was once common in Central America, and that some Great Plain Indian tribes ate dogs when food was scarce or for celebrations.
”It was definitely an accepted practice among many populations,” he said.
