A study at Emory University suggests that dogs aren’t strictly the food-obsessed beasts they’ve traditionally been seen as — and that many, maybe even most, prefer attention and praise over a chewy treat.
While only 13 dogs participated in the study, there were only two of them who — judging from their neural reactions — showed a distinct preference for food over praise.
The study, published in the journal Social, Cognitive and Affective Neuroscience, is one of the first to combine brain-imaging data with behavioral experiments to explore what kind of rewards canines prefer.
“We are trying to understand the basis of the dog-human bond and whether it’s mainly about food, or about the relationship itself,” says Gregory Berns, a neuroscientist at Emory and lead author of the research.
“Out of the 13 dogs that completed the study, we found that most of them either preferred praise from their owners over food, or they appeared to like both equally. Only two of the dogs were real chowhounds, showing a strong preference for the food.”
Berns heads the Dog Project in Emory’s Department of Psychology. It was the first to train dogs to voluntarily enter a functional magnetic resonance imaging (fMRI) scanner and remain motionless during scanning, without restraint or sedation.
Their previous research using the technique identified the ventral caudate region of the canine brain as a reward center and showed that region responds more strongly to the scents of familiar humans than to the scents of other humans, or even to those of familiar dogs.
Phys.org reports that, in the new study, researchers trained the dogs to associate three different objects with different outcomes. A pink toy truck signaled a food reward; a blue toy knight signaled verbal praise from the owner; and a hairbrush signaled no reward, to serve as a control.
The dogs then were tested on the three objects while in an fMRI machine. Each dog underwent 32 trials for each of the three objects as their neural activity was recorded.
Four of the dogs showed a particularly strong activation for the stimulus that signaled praise from their owners. Nine of the dogs showed similar neural activation for both the praise stimulus and the food stimulus. And two of the dogs consistently showed more activation when shown the stimulus for food.
Berns says the findings run counter to the old view that dogs “just want food and their owners are simply the means to get it … Another, more current, view of their behavior is that dogs value human contact in and of itself.”
In another part of the study, dogs were put into a Y-shaped maze in which one path led to a bowl of food and the other path to the dog’s owner.
The dogs were repeatedly released into the room and allowed to choose one of the paths.
While most dogs alternated between the food and their owner, dogs who showed a greater response to praise in the first part of experiment chose to go to their owners 80 to 90 percent of the time.
Berns said the study “shows the importance of social reward and praise to dogs. It may be analogous to how we humans feel when someone praises us.”

A new medication that claims to soothe dogs who are frightened by loud noises, such as fireworks and thunderstorms, will be available to veterinarians in the U.S. within a week — in plenty of time to help make the 4th of July less traumatic.
Sileo (not a very serious sounding name, is it?) comes in a gel form and is the first prescription medicine for treating anxiety over loud noises in canines– a widespread problem that leads to property destruction, running away and life-threatening injuries.
Its U.S. maker, Zoetis of Florham Park, New Jersey, says Sileo (pronounced SILL-lee-oh) works by blocking norepinephrine, a brain chemical similar to adrenaline that pumps up anxiety.
It is applied to a dog’s gums via a pre-filled, needle-less syringe.
Zoetis says the medication will give owners of the estimated third of the 70 million dogs in the U.S. who have problems with loud noises an alternative to human anti-anxiety pills, like Xanax, that sedate dogs for many hours.
Sileo takes effect within 30 minutes to an hour.
The pre-filled applicator costs $30, and contains enough for two doses for a dog of 80 to 100 pounds, four doses for a 40-pound dog, or six doses for a small dog.
Dogs can be re-dosed every two hours, up to five times during each noise event, Zoetis said in a press release.
Zoetis has exclusive rights to distribute Sileo in the U.S. under an agreement with the medication’s developer, Orion Corp. of Finland.
In testing on 182 pet beagles conducted on New Year’s Eve, 75 percent of their owners rated its effect good or excellent. Side effects were rare and minor, the company says.

A survey conducted for Milk-Bone says more Americans than ever are including their dogs in their New Year’s resolutions.
To which dogs, could they respond, would probably do so with a sarcastic “Gee, thanks.”
But fret not canines. Putting you on a diet ranks all the way down at nine in the top 10 list, and the most popular resolutions are mainly ones dogs would wholeheartedly support.
And keep it mind, we humans hardly ever carry out our resolutions, anyway.
Three thousand pet owners were surveyed, and the most popular resolutions were:
1. I will spend more time with my dog. (52%)
2. I will help my dog to have better health and wellness. (42%)
3. I will take my dog on more trips with me. (34%)
4. I will brush my dog’s teeth regularly. (31%)
5. I will help my dog get essential vitamins and nutrients.(30%)
6. I will help my dog become less anxious and stressed. (29%)
7. I won’t feed my dog food from the dinner table. (25%)
8. I won’t leave my dog home alone for quite so long. (23%)
9. I will help my pet lose weight. (21%)
10. I will take my dog to dog training class. (15%)

In a big, impersonal, sometimes mean and generally hurried city, it’s nice to see creatures — especially those of different species — taking the time to get to know each other.
Maybe that (as opposed to it being a slow news day) is why Gothamist seems to be making a Labor Day tradition of presenting videos of dogs bonding with horses, police horses in particular.
This year’s “report” — and I use that term loosely — expands on the collection of videos the website presented about this same time last year — all featuring tender, or at least inquisitive moments between city dogs and police horses.
Perhaps best enjoyed without commentary, the 11 videos show dog-and-horse bonding, sniffing, and or licking — though not all were from the streets of New York. To see them all, go here.

A veterinary student in Poland is facing expulsion after he stitched “I Love You” into the skin of a dog he had operated on — then posted a photo of his handiwork on Facebook to impress his girlfriend.
Staff at the University of Warmia and Mazury in Olsztyn launched an investigation after becoming aware of the pictures, which have been widely shared on Facebook by horrified dog lovers.
The fourth-year student was not publicly identified.
“Saying you love someone is not a bad thing,” the university’s head of veterinary studies, Andrzej Koncicki, told the Croatian Times.”But the fact this was stitched into the stomach of an animal does seem immoral and unethical behavior from a student of veterinary science … We need to find out more about what happened here.”
The student’s girlfriend defended his actions, saying, “What’s so unethical about it? He’s learnt to sew in order to help and is just showing his skill.”
The university offers a veterinary service for locals including some free treatments to allow students to test their skills, supposedly while under supervision from qualified professionals.
Where the supervision was in this case is among the questions the university says it is looking at.

With more than 500 canine clones now roaming the world, you wouldn’t think the fact that one has been produced for a pet owner in the UK would make such a big splash.
But it has, and a big splash is just what the cloners had in mind.
To introduce its unique service to Britain, Sooam Biotech, the South Korean laboratory that’s now the only company cloning dogs, borrowed from an earlier chapter in dog cloning’s bizarre history. It held a public contest, awarding a free cloning as the grand prize.
The winner: Rebecca Smith, 29, of London, who learned in late March that a clone of her 12-year-old dachshund Winnie had been born in a Seoul laboratory, BBC reported.
She named the dog Mini Winnie.
The competition saw dog owners submit videos of their dogs and compete for the chance to “immortalize” their pet for free. The bill for dog cloning normally runs around $100,000.
“Sooam Biotech is looking for one person with the most special and inspiring reason for cloning his/her beloved dog,” the company said in announcing the contest.
The contest was similar to one held in the U.S. when dog cloning first hit the market. It was called the “Golden Clone Giveaway,” and the winner was TrakR, a search and rescue dog whose owner said the German shepherd found the last survivor in the rubble of 9/11.
The weird and wacky story of how dog cloning was achieved, how it was marketed, and the first customers to sign up for it can be found in my book, “DOG, INC.: The Uncanny Inside Story of Cloning Man’s Best Friend.”
The UK’s first canine clone — who won’t arrive in the country until after a 6-month quarantine period — was cloned at Sooam Biotech, a laboratory run by Hwang Woo Suk, who was a member of the Seoul National University team that produced the world’s first canine clone, Snuppy, in 2005.
That research began after an earlier effort to clone a dog in the U.S., at Texas A&M University, was unsuccessful.
The Texas A&M research was funded by John Sperling, founder of the University of Phoenix. After cloning a cat, and assorted farm animals, the Texas A&M efforts to clone a dog were called off, but Sperling’s front man, who had established a company to store the cells of dead and dying dogs (Genetic Savings & Clone), even before dog cloning was achieved, later teamed up Hwang and Sooam to offer an online auction, with the highest bidders receiving clones of their dogs.
Hwang founded his lab after getting fired from Seoul National University when his claim to have produced the world’s first cloned human embryos was deemed fraudulent. He was later convicted of embezzling research funds and illegally buying human eggs, but his 18-month sentence was suspended.
Hwang has more recently has embarked on trying to clone a woolly mammoth from 10,00-year-old remains found frozen in Siberia.
Meanwhile, he’s churning out laboratory-created dogs, more than 500 of which have been born to surrogate mother dogs at his lab and kennel.
To create Mini Winnie, a piece of skin was taken from Winnie and transported to Seoul. Cells from the sample were placed inside an anonymous donor dog’s egg cell and, with a jolt of electricity, they merged.
Then the embryo was implanted inside a surrogate dog that gave birth, via Caesarean, to Winnie on March 30.
“The world would be a better place with more Winnies in it,” Smith, 29, says in a Channel 4 documentary, “The £60,000 Puppy: Cloning Man’s Best Friend.”
Smith received the original Winnie as a present on her 18th birthday, and she says the dog helped her overcome “lots of demons,” including an eating disorder. Smith says Mini Winnie looks identical to the original, who is old and arthritic, but still alive.
Hundreds of pet owners have had dogs cloned since the first customer, a California woman who received five copies of her dead pit bull, Booger.
Critics of the process say cloning doesn’t result in the resurrection of an animal, but a laboratory-made twin, whose creation requires the involvement of numerous other dogs, and who might not act like the original at all.
Initially, two South Korean companies were cloning dogs for pet owners (and even more for research purposes), but one of the, RNL Bio, has pulled out of the dog-cloning business.
While the cloning process has grown more efficient, some animal welfare groups say risks are still high.
Dr Katy Taylor, Head of Science at The British Union for the Abolition of Vivisection, said: “Cloning is a very unpredictable and extremely wasteful process … In order to produce just one ‘perfect’ clone, many puppies with the same genes as a loved animal will be born … Some of these puppies will be aborted or will die soon after birth from unpredictable health complications and severe birth defects.”
Defective pups, and the South Korean laboratory’s failure to follow animal welfare protocols, were among the reasons cited by the American company that teamed up with Hwang for pulling out of its dog cloning arrangement.
The documentary, while it mostly follows the judges as they visit with contestants and their dogs, does go some interesting places, including Edinburg, for an interview with Sir Ian Wilmut, cloner of Dolly the sheep. Wilmut doesn’t endorse pet cloning, and says he remains skeptical of it, saying it will lead to lots of disappointed customers who, despite their hopes, won’t get an animal with the same personality as the original.
There’s also an interview with a pet owner, not a contestant, who views dog cloning as a Hitleresque pursuit, and there are several allusions to the fact that some Koreans eat dog meat.
“The £60,000 Puppy: Cloning Man’s Best Friend” was made by the same independent production company that produced “I Cloned My Pet,” several episodes of which appeared on TLC.
“The £60,000 Puppy” is an improvement over those productions, which brushed aside most ethical questions and animal welfare concerns about pet cloning. While the new documentary doesn’t delve too deeply into them either, it does present something more than a one-sided view.
Like the earlier documentaries, it reinforces that most customers of dog cloning are, shall we say, eccentric sorts, and that their attachment to their dogs — as with all of us — is a powerful one.
Perhaps the most telling moment, though, comes as the judges debate — American Idol style — the public relations benefits of each contestant.
After that, the winner is … after a long, long pause … announced.
Cloning, it seems, is no longer some futuristic pipedream. It has become a reality, and apparently an entertainment form.
My view? Cloning is no game show, or at least it shouldn’t be.

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.
