A dog cemetery that goes back to Aztec times has been uncovered beneath an old apartment building in Mexico City.
Archaeologists announced the discovery Friday and said that — while the remains of dogs have been found in Aztec ruins before — this is the first time a group of dogs has been found buried together at one site.
The 12 dogs were buried around the same time in a small pit between 1350 a 1520 A.D., according to the Associated Press.
Aztecs believed dogs could guide human souls into a new life after death, and it was not uncommon for dogs to be buried under monuments under the thinking their spirits would provide protection.
The team of archaeologists determined when the dogs were buried through ceramics and other items found in nearby pits under the apartment building in the populous Mexico City borough of Aztacapozalco.
Archaeologist Rocio Morales Sanchez said digging deeper could help reveal why the dogs were buried there.
Experts with Mexico’s National Institute of Anthropology and History, or INAH, called the find “exceptional.”
Archaeologist Antonio Zamora, who works at the excavation site, said a biologist told the team the remains belonged to medium-sized dogs, likely Techichi dogs, a breed believed to be an ancestor of the Chihuahua, and Xoloitzcuintlis.

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!

I’ve often wondered why my dog Ace circles before he poops. He’ll go into a semi-squat, then, like a lazy Susan, make two or three revolutions before unloading.
Could it be he has an “inner compass” and is getting himself in line with the earth’s axis?
A new study suggests that canines line up along magnetic field lines to do their business. How they do that remains a mystery; why they do that perhaps an even bigger one.
Maybe they know something we don’t — we being so far removed from the natural world that we mindlessly let our toilets dictate the direction we face while defecating.
Who knows how much better off our digestive health might be, how much better aligned our chakras might be, if we all voided while facing directly north or south?
Whether there are benefits to parallel pooping — for humans or dogs — are not matters the Czech and German researchers addressed in their paper, recently published in Frontiers in Zoology.
Instead, the research focused on whether dogs – like cattle, deer and foxes – line up parallel to the earth’s axis when they defecate.
Over a two-year period, the researchers observed 70 dogs, of 37 different breeds, as they went on outings, and duly logged each urination (5,582) and defecation (1,893), as well as the direction the dogs were facing while doing the deed.
They say the results lend credence to the suggestion that dogs and other animals have some sort of internal mechanism that helps guide them in matters of pooping, and likely much more — at least when the earth’s magnetic field is stable.
The earth’s magnetic field is stable is only about 20 percent of the time during daylight, they note. But when looking only at those periods, dogs off leash seemed to prefer to poop with their bodies oriented along the north-south axis, the study said — facing either directly north or south. As for peeing, female dogs did that while aligned with the north-south axis, while male dogs preferred a northwest heading.
The researchers say that if dogs are capable of “magnetoreception,” it would open “totally new horizons for magnetobiological research.”
As for why the dogs do it in the first place, the authors said, “An answer may lie in the biological meaning of the behavior: If dogs would use a visual … magnetic map to aid general orientation in space, as has been proposed for rodents, they might have the need to center/calibrate the map now and then with regard to landmarks or a magnetic reference …We might think of this the same way as a human is stopping during a hike to read a map.”
In other words, maybe dogs use pooping as an opportunity to take stock, get their bearings, plot their next step and better understand their place in the universe.
Humans sometimes do that on the toilet, too, I’d venture, especially when they run out of magazines to read.
And while most humans don’t put much thought into what direction they’re facing during the act, or whether they’re aligned with the earth’s axis, there are some who advise taking that under consideration.
In a cursory — highly cursory — search of the Internet, we found a website called Vaastu NaresH, which suggests a water closet that faces north or south will lead to increased health and happiness. Another feng shui-related website advised one’s entire bathroom face north — not so much to align with the earth’s axis, but because that’s where the malevolent spirits are.
(I’m not sure the malevolent spirits appreciate being honored that way, whether they might prefer that you, instead of offering a full view, shut the door and turn on the exhaust fan. Then again, they are malevolent.)
As for dogs, I’ve never noticed any consistent alignment when it comes to defecating. My dog Ace seems to be an omni-directional pooper, basing his stance on whether the sun is in his eyes, whether there’s something interesting to watch off in the distance in some particular direction, how urgent the situation is, or simply what point he’s at in his urgent and dervish-like pre-poop spin when nature finally calls.
Then again, what do I know? My toilet faces southeast.

The older I get the more wary I become of technology.
What I haven’t figured out is whether one necessarily follows the other: Am I just becoming more fearful as I age, or is technology proving itself more worth fearing?
Both are unstoppable forces. Just as one can’t stop the march of time (even with anti-aging technology), one can’t stop the march of technology.
It keeps coming — whether it’s wise or not, safe or not — and we all blindly jump on board and become dependent on it. If it makes us prettier, gets us where we’re going, let’s us accomplish things more quickly, or function without actually using our brains, we humans are generally all for it.
Already we’re reliant on the Internet, GPS, and cell phones. Already we can purchase almost anything we want online. But the day may soon come when, once we order it, it gets delivered by a robot, perhaps a flying one, or a terrain-traversing one, or one capable of hurling 35-pound cinder blocks 17 feet.
I would say these robot dogs could become the newspaper delivery boys of tomorrow, if newspapers had a tomorrow.
Last month 60 Minutes revealed that Amazon was working on drones that will be able to fly to homes and deliver packages at our doorstep.
Last week the New York Times reported that Google has purchased Boston Dynamics, the engineering firm that designed the graceful beast known as “Big Dog” (seen in the video above) and other animal-like robots, mostly for the Pentagon.
It is the eighth robotics company that Google has acquired in the last half-year, but Google’s not divulging what it’s up to.
Given search engines don’t generally need to climb mountains, or hurl cinder blocks, to find their information, one can only wonder.
Is the company branching into war machines? Does it want to corner the market on robot pets? (Boston Dynamics did serve as consultant on Sony’s ill-fated pet robot dog, Aibo.) Is it hoping to take Google Earth one step further and have robots take photographs through our windows? Or, more likely, is Google, like Amazon, positioning itself to become the place where you buy everything, and working on lining up a delivery team whose members don’t require salary, or health insurance, or coffee and pee breaks?
It almost looks like Amazon is poised to cover air delivery, while Google, with its latest purchase, is positioning itself to cover the ground. (That, at least until Big Dog becomes amphibious, leaves the high seas open — aye, aye robot! — for, say, a Yahoo, Bing or eBay).
Boston Dynamics, based in Waltham, Mass., builds animal-like machines that can traverse smooth or rocky terrain, some of them at speeds faster than a human. Most of its projects have been built under contracts with Pentagon clients like the Defense Advanced Research Projects Agency, or DARPA.
Google executives said the company would honor existing military contracts held by Boston Dynamics, but that it did not plan to become a military contractor on its own.
So why does it need computers with legs, or robots that can climb walls and trees? Surely Google isn’t working on ”Terminators” that can track you down, knock on your door and provide you with the top 10 recipes for apple crumb cake.
The Times reports: ”… Executives at the Internet giant are circumspect about what exactly they plan to do with their robot collection. But Boston Dynamics and its animal kingdom-themed machines bring significant cachet to Google’s robotic efforts … The deal is also the clearest indication yet that Google is intent on building a new class of autonomous systems that might do anything from warehouse work to package delivery and even elder care.”
EVEN ELDER CARE? Oy, robot! I do not want a robot dispensing my medication if I end up in such a facility. At that time, I will be even more terrified of technology, and the last thing I would want to see would be a robot coming into my room – no matter how sexy its voice – saying, “Time for your sponge bath.”
I’m not a total Luddite.
I can publish a website or two, and can hook up my cable TV, and can figure out about 10 percent of what my cell phone does.
But I resent how steep the learning curve has become — how much effort is involved in keeping up with technology. That device promising to make life easier — once you spend a week programming it — may be smaller than your little finger, but its owner’s manual will be fatter than a James Michener novel.
What I fear, though, is where technology can lead, especially technology without forethought, and how quickly and blindly many of us hop on the bandwagon, giving little consideration to the possible repercussions, and how easily it can run amok.
The one futuristic (but already here) technology I’ve researched most is dog cloning. Once achieved, the service was offered to pet owners hoping to bring their dead dogs back to life, and willing to pay $150,000 for that to be accomplished in South Korean laboratories. It bothered me so much, and on so many levels, I wrote a whole book about it. You can order it through Amazon, but don’t expect drone delivery for at least a couple more years. Might one day drones deliver our clones?
I realize my fears are both irrational and rational.
Fretting about the future, I guess, is part of getting older. Old fart worries were around back when automobiles first hit the road (and went on to become a leading cause of death). And it’s probably true that once we stop moving forward, we tend to stagnate. But there’s moving forward and smartly moving forward.
I’m not a fan of big government (except when it helps me get health insurance), but I sometimes wonder if we need a federal Department of Whoa, Let’s Take a Look at this First. Maybe it could monitor emerging technologies, and their ramifications, and determine whether they should be allowed to emerge at all. Maybe that would prevent unimaginable (but, with enough research, entirely predictable) things from happening — like cell-phone shaped cancers forming on the exact spot of our bodies where we pack our cell phones.
But we tend to be more reactive than proactive when it comes to those kinds of things. We wait for the damage to be done and leave it to personal injury lawyers to straighten it out — whether it’s a new anti-psychotic drug that unexpectedly made young males grow female breasts, or irreparable harm done by robotic surgical devices. (If you’ve been victim of either, lawyers are standing by to help you. At least that’s what my TV tells me.)
I want to enter my golden years without shiny silver robots assisting me in living, and without drones hovering outside my door (even if they are delivering a good book). Though I’ve met some clones, I wouldn’t mind getting through life without having any contact with droids and drones and robot dogs.
Sometimes, at least from the Fearful Old Man Perspective (FOMP), it seems we’re so focused on the future that we fail to see and appreciate the present, and don’t even begin to learn from the past.
Sometimes it seems we like dancing on the cutting edge, then cry foul when our feet get sliced up.
Sometimes it seems we embrace technology too quickly and casually, when it should be a careful and thoughtful embrace, made with the realization that, as much as technology can make life better, it can also screw it up badly. We tend to view technology in terms of what it can add to our life, not even considering what it might subtract. And, in what’s the biggest danger of all, we tend to let it overrule our hearts and do our thinking for us.
It can save and prolong lives, even, in a way, re-create them. It can make our human lives – though it’s arguable — more convenient.
But it can also gnaw away at us until we become tin men and scarecrows — maybe not actually missing our hearts and brains, but at least forgetting we ever had them.

I’m a big fan of dogs, and not a fan of dentistry at all, so as you might expect I’ve got some problems with dogs being used to test out dental implants, in hopes of making better and safer ones for humans.
Especially considering that dogs are suffering and dying in the process, as The Humane Society of the United States says is the case at Georgia Regents University.
The HSUS last week released this report, containing undercover footage obtained during its three-month-long investigation at GRU. The experiments lead to two questions in my mind.
First, since the research is supposed to benefit humans, why not use humans for the tests? I’m sure there are plenty of people who are in need of dental implants and who, unable to afford them, might be willing to volunteer. I myself might take the risk, assuming that the researchers don’t insist on killing me afterwards to get a sample of my jawbone.
And that’s question number two: Why is it necessary to kill a dog after he’s already made an unwilling contribution to science — or at least a contribution to us humans being able to have gap-free permanent false teeth and not having to mess with things like denture adhesives?
As one dentist told the Humane Society, it’s not.
“In the two studies I reviewed, human research subjects could have been used, given that the products were already approved by the Food and Drug Administration and bone biopsies are commonly done in human studies,” said James P. Jensvold, DDS.
“Animals used in research are often ‘sacrificed’ at the end of the study, and this is accepted as standard practice without taking into consideration the unnecessary emotional and physical suffering that the animals must endure,” Jensvold added. “As a dental student and oral and maxillofacial surgery resident, I witnessed laboratory animals being treated as little different than a test tube, which is inconsistent with the values of compassionate healthcare.”
“Dogs don’t need to die for frivolous dental experiments,” said Wayne Pacelle, HSUS president and CEO. “It’s painful to watch these forlorn dogs sacrificed for these questionable purposes…”
If you tend to distrust dentists, and Wayne Pacelle, perhaps you’ll believe actress Kim Basinger, who narrates the HSUS report:
“GRU buys dogs from a Class B dealer who’s under federal investigation,” she notes. “Dogs like Shy Guy, along with others, who may have been famiily pets, were all used for unnecessary dental experiments. Their teeth were pulled out and replaced. It’s very painful, just look into their eyes.”
(Dogs used in the experiments, after having their teeth removed, are given a canine version of dental implants, not human ones, like you find in those freakish — to me, anyway — ads for Pedigree Dentastix.)
The HSUS investigator witnessed dogs having their teeth pulled out and replaced with implants. Once the experiments were over, the dogs were euthanized for a small sample of their jaw bone. GRU has been conducting dental implant research on random-source Class B dogs for years.
There are only six random-source Class B Dealers still active in the U.S. They are permitted to gather dogs and cats from various sources, including auctions, “free to good home” ads, online sources, flea markets, and even animal control and some shelter facilities — and resell them to research facilities. There have been cases of stolen pets ending up in research laboratories via ClassB dealers, the HSUS says.
The dealer who sold the dogs to GRU, Kenneth Schroeder, has previously been charged by the U.S. Department of Agriculture with violations of the Animal Welfare Act, including obtaining dogs from unauthorized sources, according to the HSUS.
Dr. Mark Hamrick, Senior Vice President for Research at Georgia Regents University, issued the school’s response to the HSUS allegations:
“As an institution, we are committed to research that will provide a direct benefit to patient lives by restoring function to damaged and diseased organs and tissues … The Food and Drug Administration, which provides oversight for medical device safety and procedures including dental implants, requires preclinical studies in animals demonstrating that the device or procedure is both safe and effective for its intended use in humans … The research being done with dogs is neither frivolous nor unnecessary, as alleged by the investigation, and is performed in order to develop safe, effective dental procedures for people.”
The HSUS says the studies are being done at the university in part to compare a dental implant invented by researchers at GRU, in conjunction with a private company, with that of a competitor.
According to the HSUS, 65,000 dogs per year are used for research, testing, and education in the U.S.

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.”

Call it an “aha” moment for the AHA: The American Heart Association has finally, officially, recognized that dogs are good for the ticker.
Last week, the organization issued a statement saying enough evidence now exists to make that assertion, and it didn’t even recommend dogs be taken in moderation, or consulting your doctor first.
Heartening as the news release was, the statement was overdue, or at least a few beats behind the thinking of those of us who already knew, and didn’t need studies to tell us, that our dogs are good for the heart, by which I mean the organ and more.
Dog owners are more likely to get exercise. Stroking a dog lowers blood pressure. Stress is handled better by dog owners — even when their dog isn’t with them. Studies have proven all those things.
But the mysteries of what dogs do for the heart, and the soul, have only begun to be unraveled. And on top of all the benefits to humans that can be scientifically confirmed and quantified, there’s much more dogs do for us — much of it undetectable by microscopes and double-blind studies, and part of me hopes it always will be.
Being humans, we can sometimes get so wrapped in measuring something that it interferes with treasuring that something. We can get so intent on delving into something’s complexities that we fail to savor its simplicity.
Dogs, could they speak, would tell us that, and they’d likely advise to look for the simple answer first.
How important, heart-wise, is the simple fact that a dog can give us reason to live, and love? While I am not a medical professional, or even a medical amateur, I think a heart that’s engaged and occupied is more likely to keep running smoothly than one sitting empty in the garage, getting dusty.
“Perhaps when one owns a pet one tends to be happier,” said Dr. Glenn Levine of Baylor College of Medicine in Houston, who led the committee that wrote the statement. “Pet owners might be more likely to take their medications and eat healthier meals.”
Pharmaceuticals and spinach, important as they may be, don’t make you happy to be alive, though, and want to continue in that state.
The AHA isn’t saying everyone should go out and adopt a dog to lower their risk of heart disease. The statement emphasizes there’s much more involved in keeping your heart healthy, according to an NBC Today report.
“We did not want people to see this article and just go out and adopt or rescue or buy a dog …while they continue to just sit on the couch and smoke cigarettes,” said Levine, himself a dog owner.
In one study cited by the committee, researchers signed up 30 people with borderline high blood pressure who were about to adopt dogs from a shelter.
Then they persuaded half of them to wait — in the best interest of the study, if not the dogs.
Those allowed to adopt dogs right away had lower blood pressure two and five months later than those who had not adopted.
And once all the study participants had adopted dogs, systolic blood pressure was found to be lowered in the deferred-adoption group as well.
The study didn’t say whether those that adopted had lower blood pressure than those who bought dogs. Nevertheless, and even though I’m not a doctor, that’s what I’d prescribe.

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.

It’s the one-year anniversary for 120 beagles who, around this time last year, learned the true meaning of independence.
Up until then, even here in the land of the free, they weren’t.
Instead, like thousands of other beagles bred and born for the sole purpose of laboratory use, they’d never experienced what most dogs take for granted — things like grass and dirt and running — and were destined, once their use in testing was complete, for something quite contrary to a loving home.
The beagles had been left locked in a research facility operated by Aniclin Preclinical Services in Warren County, N.J. after its parent pharmaceutical company went bankrupt. When their situation came to light, a judge order the dogs turned over to rescue groups.
One year ago, a group of them were welcomed to Pets Alive Animal Sanctuary in New York, where work began on socializing them so they could be adopted out as family pets.
This coming Sunday, some of them will gather for a reunion.
About 35 of the adopters stay in touch on Facebook, offering support and following each others progress through photos and stories.
They — and any of the others who adopted a “freegle,” as they are prone to calling the dogs rescued from the laboratory — are gathering July 10, from 12:30 to 4 p.m., at Kennedy Dells Park, 355 North Main Street in New City, New York.
Among those attending will be a beagle named Grace, who has her own Facebook page, called Saving Grace. Grace’s owner said that while word of the reunion has gotten out among those who stay in touch, other beagles adopted from the group are also invited, as well as everyone else who participated in rescuing them.
Shelters, sanctuaries, volunteers and staff are “most welcome to attend and meet the families and hear the stories of how the Freegles have been adjusting to the good life.”
(For questions or to RSVP, send an email to firstname.lastname@example.org.)
I met several lab beagles while researching my book — including some flourescent beagle clones in South Korea. In Texas, I interviewed the woman who cared for the beagles used in attempting to clone a dog at Texas A&M University.
Jessica Harrison, a graduate student at the time, was in charge of socializing the beagles and finding adoptive homes for them — not usually the case or fate of laboratory beagles — after their services in the lab were no longer required.
“What they teach them is to be still,” she told me. “As puppies, they teach them to just freeze when a person messes with them. We had to kindo of undo that and say, ‘No,we want you to move around and be excited.’
“We slowly exposed them to all the things they’d be exposed to in a family home — like TVs, mirrors, grass, trees, flowers, birds and bees. These dogs had never seen any of that. You put them down on the grass, and they’re like, ‘What’s this?’ It was kind of overwheliming. You get used to it, but at first it’s like, these are dogs, how can they not know these things?”
The use of dogs in laboratory research was declining, but it has jumped up in recent years, with much of the increase due to advancements in, and the promise of, gene therapy.

Seventy-five years after his death, scientists say they have determined what killed Hachiko, the legendary Akita whose story has been immortalized in his native Japan and the rest of the world.
Japan’s most famous dog — though rumors have persisted for decades that worms did him in, or that he swallowed a chicken skewer that ruptured his stomach — had heart and lung cancer, scientists now say.
Hachiko became legendary for the loyalty he showed by waiting for his owner every day at a train station — for 10 years after his master died.
Hachiko died in 1935 at the age of 13. After his death, researchers at what is now the University of Tokyo performed an autopsy on Hachiko’s body and discovered roundworms in his heart and liquid collected in his abdomen.
Using more sophisticated tests like MRI’s, the Mainichi Daily News reports, a team of scientists at the University of Tokyo team analyzed Hachiko’s preserved organs and discovered large cancers in the heart and lungs. They speculated that the cancer may have spread from the lungs to the heart. Hachiko also had filariasis (a worm-caused diseased), and it’s possible that could have caused his death as well, said professor Hiroyuki Nakayama, part of the research team.
Hachiko’s preserved organs are displayed at a University of Tokyo resource center in Bunkyo Ward, Tokyo, along with a bust of his owner. A “stuffed” Hachiko is also on display at the National Museum of Nature and Science in Tokyo’s Taito Ward. A statue of Hachiko was erected in his honor at Shibuya Station.
Hachiko accompanied his owner, a university professor named Eisaburo Uyeno, to the train station every day and watched him leave for work. Every evening the dog would be waiting for him when he returned. When Uyeno died, Hachiko continued going to the train station every day to wait for his master for about ten years.
The legend has been told in numerous forms in the 75 years since, most recently as a childrens’ book and a 2009 movie remake, re-set in Rhode Island, starring Richard Gere.
