High tech device promises to tell a dog’s mood — by monitoring the wag of the tail

Yes, ohmidog! pokes cruel fun at “new technology” from time to time, but only when “new technology” deserves it — as is the case with this tail wagging monitor a group hopes to bring to the market.

Some Cornell University graduates have launched an Indiegogo campaign to finance the manufacturing of DogStar TailTalk, which they describe as a translator of dog emotions.

The device consists of a lightweight sensor that wraps around your dog’s tail, monitoring the speed and direction of the tail’s movement with an internal accelerometer and a gyroscope.

Coupled with a phone app, the developers say, it will tell you when your dog is happy, and when his or her tail wag may be a sign of stress.

wagThere’s some hard science behind it — but not much.

Scientific studies conducted in Italy have concluded that the prominent direction of a dog’s tail wag is an indicator of whether he’s happy or feeling anxiety, aggression or fear.

Wagging more to the right is said to be an indication of positive feelings.

The developers of the device say the direction of the wag isn’t always discernable to the naked eye: “Tail wagging is asymmetric and includes complex emotional signals that the human eye cannot recognize.”

We’re not so sure about that, just as we’re not so sure that a dog owner, seeing their dog’s tail wagging upon meeting, say, another dog, will have time to fire up the app to determine whether the meeting is going to go well.

Like a lot of canine-oriented technology — from treat poppers to automatic ball throwers to spy cams – this little gizmo takes over a task and/or responsibility that we should be doing ourselves, thereby growing closer and better knowing our dog, as opposed to distancing ourselves from our dog and giving them the features of robots.

As the goofy video above shows, the device may have some value when used remotely, such as learning the dog really doesn’t like the dog walker at all, but that — again — is something a dog owner should be able to ascertain beforehand without gyroscopes or apps.

The design team says it consulted on the project with “professors from the famous College of Veterinary Medicine in Cornell University.”

We think we smell a class project resurfacing for the marketplace. Not that there is anything wrong with that.

Current plans call for the TailTalk app to work with iOS or Android phones, and to include features like the “Happiness Overview” function, which tracks a dog’s emotional status over the course of a day, a week, or a month. The monitoring device will be waterproof and “chew-resistant.” We can only hope that dogs, annoyed by having a tail attachment, don’t inadvertently chew through something other than the device.

So far, the campaign has raised about a third of its $100,000 funding goal.

If all goes according to plan, the TailTalk device will be ready to hit the market in about a year, and we suspect that — just as there are those who are willing to fund it — there will be those willing to buy it.

Because while the dog may sometimes wag his tail, and the tail may sometimes wag the dog, technology seems destined to almost always wag us.

And then there were two: Class B dog dealers are all but gone, HSUS says

From 2/25/2013 to 5/24/2013, an HSUS investigator worked as a Husbandry Technician at Georgia Regents University (GRU). During her time at GRU, the HSUS investigator cared for rodents, primates and dogs. She also documented violations of: the federal Animal Welfare Act (AWA). NIH's Guide for the Care and Use of Laboratory Animals. The dogs were used in a dental implant experiment: at the end of the experiment the dogs were killed. The primates were being used in various experiments. Some of the primates exhibited stereotypical behaviors (i.e. pacing, doing "flips" in their cages, pulling out and eating their hair, etc. One primate drank his urine from his penis). The dogs came from Kenneth Schroeder (Wells, MN), a Class B Dealer currently (8/28/2013) under investigation by the USDA. Keywords: dog, end animal testing, ARI, animal research issues, Class B

The largest of the country’s three remaining Class B dog dealers — those often unscrupulous sorts who scrounge up dogs and sell them to laboratories for use in experiments — is going out of business.

The Humane Society of the United States reported yesterday that Ohio-based dealer Robert Perry has cancelled his license with the U.S. Department of Agriculture.

That means only two licensed “random source” dealers remain. Class B, or random source, dealers round up dogs from flea markets, shelters, auctions, Craigslist and other sources and sell them to research institutions.

“These merchants of cruelty are on their last gasps, and this announcement gets us one big step closer to the complete demise of this sordid trade,” Wayne Pacelle, president and CEO of The Humane Society of the United States,  writes on the HSUS blog, A Humane Nation.

Perry has been supplying dogs for years to a number of institutions, including Ohio State University. Between October 2013 and October 2014, OSU purchased nearly 50 dogs from Perry, making him the biggest random source supplier of dogs used in research nationwide.

Of the two remaining Class B dealers, one had only four dogs in its most recent inventory and the other is facing formal enforcement action from the USDA, according to HSUS.

At one time there were more than 200 licensed Class B dealers in the United States. By 2013, as a result of a decline in the use of dogs in laboratories and opposition from groups like HSUS, Last Chance for Animals, the Doris Day Animal League, and the Animal Welfare Institute, that number was down to six

Last year’s announcement from the National Institutes of Health that it would no longer fund research that used random source dogs served as a final nail in the coffin for Class B dog dealing.

The NIH decision stemmed from a report issued by the National Academy of Sciences that found random source dealers could not guarantee that people’s pets would not end up in laboratories.

Those dogs who are bred for laboratory research — commonly beagles — weren’t directly affected by that decision, but, as Pacelle notes, they are being used less often by laboratories, too.

“The continuing and rapid decline of these random source Class B dealers means the chances of pets ending up in laboratories are now very low,” Pacelle said.” And we’re perhaps closer to the day when fewer dogs of any kind are used in testing and research.”

Why some dogs chase their tails


Why do some dogs seem so obsessed with chasing their tails?

Researchers at Bristol University in the UK have entered the second phase of a study aimed at finding the answer.

Scientists from the two-year “Bristol Spinning Dog Project” will visit the homes of the 50 non-spinning dogs to collect urine samples and cheek swabs, and complete training tasks aimed at assessing the pet’s personality and ability to learn, The Independent reports.

In the first phase of the study, the researchers examined spinning dogs, delving into everything from their DNA to their environments to their personalities.

After examining dogs that chase their tails, the researchers will use the non-spinners to act as a control group.

Tail-chasing, while the topic of many a YouTube video, is likely something we shouldn’t be laughing about — out loud or otherwise — at least in those cases where the behavior is obsessive.

The researchers say reasons for the behavior aren’t fully understood — some spinning dogs may be merely seeking attention or expressing a desire to play, but spinning frequently or while alone could be a sign of frustration or a more serious disorder.

“There isn’t much information in the research literature about why dogs spin,” said Beth Loftus, one of the lead researchers. “We think this behavior develops because of personality and genetics, as well as the environment during a dog’s first 16 weeks and learning throughout life. But we don’t really know what it means for dogs’ welfare.”

“We hope to be able to identify dogs that are starting to spin and stop it from developing to the point where they are doing it almost to the complete exclusion of other, more normal types of behavior,” she added.

The research is being funded by the Dogs Trust charity.

Wayne State urged to end dog experiments


A physician’s organization led a rally this week urging Wayne State University to end its long-running series of cardiac research experiments on dogs.

About 45 people joined in the protest, led by the Physicians Committee for Responsible Medicine.

According to the nonprofit organization, the heart failure experiments have been going on for 20 years, at a cost to taxpayers of about $8 million, and have provided no information beneficial to treating human heart disease.

No dogs leave the program alive.

“These research experiments have not garnered anything that has advanced human health,” said Jennifer Giordano, a Detroit-area doctor representing the committee. “We want them to use human-relevant research methods.”

In the experiments, heart problems are induced in the dogs by the use of implanted electrodes, which cause their heart rates to more than double.

The dogs are then put through multiple surgeries and are required to run on treadmills. About 25 percent of the dogs die during or after the surgery. Those who do survive are euthanized when their participation is no longer needed.

The experiments are funded in part by the National Institutes of Health.

At the Wednesday rally the Physicians Committee for Responsible Medicine presented a letter signed by actress Lily Tomlin to Wayne State University officials, calling on them to end medical experiments on dogs. Tomlin is a Detroit native and attended the university.

In the letter, Tomlin wrote: “I understand that Wayne State is spending millions of taxpayer dollars using dogs in heart failure experiments that have not benefited human health in any way. I urge you to end these senseless experiments as soon as possible.”

A copy of the letter was given to Matt Lockwood, a university spokesman who came to the rally and a read a statement defending the experiments, the Detroit News reported.

“Almost every medical advance in the last 100 years was due to research on animals — chemotherapy, hip replacements, transfusions, dialysis — was all tested on dogs,” Lockwood said. “We need to continue to do research to advance science.”

He said the animals in the experiments are under the constant supervision of veterinarians.

“There’s a committee that’s sole purpose is to ensure the animals are as comfortable as possible,” he said. “We’re also under the oversight of the federal government and the state. Never once has any animal been found to have been mistreated at any time.”

He said the dogs are euthanized after taking part in the experiments, but he declined to provide numbers.

Does Fido want fries with that?

Revelation Research Dog at Drive Thru

One out of every six fast food customers pick up a little something for the dog at the drive-thru window, according to a study by a marketing research company.

“These visits translate to a staggering number of trips (over 1,000,000,000 annually) where the dog is the one ‘lovin’ it,’” concludes a recent study on dog ownership and fast food habits conducted by Relevation Research.

The study found just over one third of canine owners have visited fast food drive-thrus with their dog — and, of those, four-fifths claim to have ordered menu items specifically for their dogs.

McDonald’s is visited most often by dog owners, followed by Burger King and Wendy’s.

With dog ownership, and dog pampering, expected to continue to grow — especially among baby boomers and millenials — QSRs (or quick service restaurants) would be well advised to put healthy dog treats on the menu, it suggests.

“Because of disposable incomes and empty nester status, Baby Boomer owners could be strong candidates for QSR,” said Nan Martin of Relevation Research. “But the Baby Boomer also has an evolving focus on health. That means menu items specifically targeted for dogs or dog-friendly in terms of ingredients will resonate best.

“QSR and dog food/treat manufacturers should team up to design dog-safe offerings. Companies catering to the dog will win with owners who want to, guilt-free, feel like they’re spoiling the dog.”

How to stay young? How to grow old? Dogs show us the way to both


Dogs have a knack for helping us accomplish our goals. Somehow, they seem to know what those goals are without ever being told. Maybe, they know our goals better than we do.

With no apparent effort, they can help us accomplish our missions … whatever the mission … even missions that are completely opposite from one another.

Dogs, for instance, can help us stick to a routine, or get us out of a rut. (Ace has done both for me.)

They can enlarge our circles of friends, and — at those times solitude might be best — keep it from getting too lonely. (Ace has done both of those, too.)

And they can both keep us young and show us how to grow old.

That last trick, I think, is particularly impressive.

Dogs, when you think about it, show us how to live our lives (in the moment, with abandon), cope with our maladies (with brave perseverance) and die our deaths (with grace and dignity).

Between the examples they offer, the similarities between our species and the uncovered secrets dogs may still hold, it’s no surprise that science and medicine and more than a few other fields of study are increasingly turning to them for answers.

What dogs have to teach us about living a healthy life — some of it obvious (if we pay attention), some of it suspected and undergoing research — was the subject of an article last month in AARP Magazine.

As it noted, dogs, as they continue to evolve alongside us, are increasingly mirroring us, right down to getting the same diseases and disorders.

“… This evolution is ongoing, a process scientists call convergence: Human and canine genes, shaped by the environment we share, are evolving in lockstep. Today, along with home security and leftover disposal, dogs confer a host of wellness benefits, especially to kids and older people,” the article’s author, David Dudley, wrote. “People with dogs sleep better, weigh less and get more exercise than dog-free peers.”

“And there are the less tangible perks, the ones cataloged in Marley & Me–style books. This burgeoning “dogoir” literary genre revolves around the reductive but basically correct idea that a dog is foremost an instrument of personal growth: It exists to ease your existential anxieties, impart lessons about love and friendship, and teach you how to be a better person.”

But as noted by Dudley, who weaves the lessons his dog Foghat taught him into the article, that’s just the beginning of what dogs might have to share.

He cites a couple of research projects as examples of the possible answers dogs may hold when it comes to aging.

Neuroscientist Elizabeth Head is studying elderly beagles at the University of Kentucky in an attempt to determine why, by age 6 or 7, they start showing signs of the microscopic beta-amyloid plaques that are the hallmarks of Alzheimer’s disease.

About a third of the beagles will succumb to canine cognitive dysfunction syndrome, about the same percentage of Americans over 85 who will get Alzheimer’s.

“It could be that living in our environment — our food, our water, our homes — has made dogs more vulnerable,” she says.

Head thinks dogs might hold the key to defeating it. Past studies, she notes, have demonstrated that an antioxidant-rich diet and “behavioral enrichment” — a course of memory drills and new-skills training — can significantly delay or diminish plaque development and memory impairments.

At the University of Washington, Daniel Promislow, an aging researcher (in both meanings of the phrase), has assembled a team to join in a Canine Longevity Consortium. Through a a grant from the National Institute on Aging, they’re working on the first national longitudinal study on aging in dogs, which will include looking at how dogs stay so seemingly happy and carefree as they advance in years.

On the downside, as we all know, they can relatively suddenly become frail, forgetful and sick — as was the case with Dudley’s dog, Foghat.

“…He entered his dotage in roaring good health. Around his 18th birthday, I Googled “oldest dog in the world,” because I started to wonder if he was closing in on a record. He was what gerontologists would call a successful ager.

“And then, seemingly overnight, he wasn’t. If you have to go — and you do — a swift slide into decrepitude is the preferred way. The phrase is “compression of morbidity,” when the infirmities of age are delayed until the bitter end. Still, it’s no picnic. The joints went first. He started limping after a vigorous bouncing-a-soccer-ball-off-his-nose session. Then he needed help climbing into the car or crawling under the bed, his favorite sleeping spot.”

As Foghat declined, Dudley wrote, his “senescence appeared as both a comfort and a warning of what awaits: Some fears and eccentricities will lift with the years; others will only deepen. One by one, the things you love to do become too difficult and slip out of your life.”

With his death, Dudley says, “I was struck by the strange new stillness — the foreign silence of a household without a dog. It was as if a machine that had been humming in the background for a long time had suddenly been switched off.”

Amid that silence, Dudley, like many other grieving dog owners, started quantifying what he learned from Foghat.

” …And now that I’m no longer young, and he’s dead, I’ll do my best to follow the path Foghat blazed into my life’s last half…” he wrote.

“So eat the best food you can afford. Go for a walk, even if it’s raining. Take a lot of naps. Keep your teeth clean and your breath fresh, so that the people you lick will not flinch. And when someone you love walks in through the door, even if it happens five times a day, go totally insane with joy.”

Study says dogs go back no more than 12,000 years


A new study has a bone to pick with earlier researchers who concluded the domesticated dog has been around for 30,000 years.

New 3D analysis of skulls that had been identified as two of the earliest dogs shows they were actually wolves, a research team writes in the Nature journal Scientific Reports.

Fossilized remains that scientists said showed dogs date back at least 31,680 years — specifically those remains unearthed at Goyet Cave in Belgium — actually belonged to a wolf, according to a new study. So too, the new study says, did a 13,905-year-old fossil that was identified as belonging to a dog after it was found at a site called Eliseevichi in Russia.

The new study concludes that the the domestication of dogs happened during the Neolithic era (10,200 B.C.-2,000 B.C.) as opposed to the Paleolithic era (2.6 million years ago to 10,200 B.C.)

“Scientists have been eager to put a collar on the earliest domesticated dog,” lead author Abby Grace Drake said. “Unfortunately, their analyses weren’t sensitive enough to accurately determine the identity of these fossils.”

“Previous research has claimed that dogs emerged in the Paleolithic but this claim is based on inaccurate analyses,” Drake told Discovery News. “We reanalyzed some of the fossil canids from the Paleolithic and show that they are, in fact, wolves.”

“We did confirm that the Neolithic specimens Shamanka II (around 7,372 years old) and Ust’-Belaia (about 6,817 years old) are dogs, and therefore domestication took place by this time period or earlier,” added Drake, an assistant professor of biology at Skidmore College.

That means the wolves — who are generally (but not unanimously) believed to have evolved into dogs, possibly as a result of their interacting with humans — first appeared on earth after humans were farming and living in settlements, as opposed to when they were living in caves and hunting and gathering.

Drake and colleagues Michael Coquerelle and Guillaume Colombeau used scans and 3D visualization software to study the shape and size of the two oldest skulls and compare the data with measurements from the skulls of other dogs and wolves, according to a report on

That technique allowed the team to identify subtle morphological differences between dogs and wolves, such as the direction of the eye cavity and the angle between the muzzle and forehead.
