If You Want to Know if Spot Loves You So, It’s in His Tail
By Sandra Blakeslee

Every dog lover knows how a pooch expresses its feelings.

Ears close to the head, tense posture, and tail straight out from the body means “don’t mess with me.” Ears perked up, wriggly body and vigorously wagging tail means “I am sooo happy to see you!”

But there is another, newly discovered, feature of dog body language that may surprise attentive pet owners and experts in canine behavior. When dogs feel fundamentally positive about something or someone, their tails wag more to the right side of their rumps. When they have negative feelings, their tail wagging is biased to the left.

A study describing the phenomenon, “Asymmetric tail-wagging responses by dogs to different emotive stimuli,” appeared in the March 20 issue of Current Biology. The authors are Giorgio Vallortigara, a neuroscientist at the University of Trieste in Italy, and two veterinarians, Angelo Quaranta and Marcello Siniscalchi, at the University of Bari, also in Italy.

“This is an intriguing observation,” said Richard J. Davidson, director of the Laboratory for Affective Neuroscience at the University of Wisconsin in Madison. It fits with a large body of research showing emotional asymmetry in the brain, he said.

Research has shown that in most animals, including birds, fish and frogs, the left brain specializes in behaviors involving what the scientists call approach and energy enrichment. In humans, that means the left brain is associated with positive feelings, like love, a sense of attachment, a feeling of safety and calm. It is also associated with physiological markers, like a slow heart rate.

At a fundamental level, the right brain specializes in behaviors involving withdrawal and energy expenditure. In humans, these behaviors, like fleeing, are associated with feelings like fear and depression. Physiological signals include a rapid heart rate and the shutdown of the digestive system.

Because the left brain controls the right side of the body and the right brain controls the left side of the body, such asymmetries are usually manifest in opposite sides of the body. Thus many birds seek food with their right eye (left brain/nourishment) and watch for predators with their left eye (right brain/danger).

In humans, the muscles on the right side of the face tend to reflect happiness (left brain) whereas muscles on the left side of the face reflect unhappiness (right brain).

Dog tails are interesting, Dr. Davidson said, because they are in the midline of the dog’s body, neither left nor right. So do they show emotional asymmetry, or not?

To find out, Dr. Vallortigara and his colleagues recruited 30 family pets of mixed breed that were enrolled in an agility training program. The dogs were placed in a cage equipped with cameras that precisely tracked the angles of their tail wags. Then they were shown four stimuli through a slat in the front of the cage: their owner; an unfamiliar human; a cat; and an unfamiliar, dominant dog.

In each instance the test dog saw a person or animal for one minute, rested for 90 seconds and saw another view. Testing lasted 25 days with 10 sessions per day.

When the dogs saw their owners, their tails all wagged vigorously with a bias to the right side of their bodies, Dr. Vallortigara said. Their tails wagged moderately, again more to the right, when faced with an unfamiliar human. Looking at the cat, a four-year-old male whose owners volunteered him for the experiment, the dogs’ tails again wagged more to the right but in a lower amplitude.

When the dogs looked at an aggressive, unfamiliar dog — a large Belgian shepherd Malinois — their tails all wagged with a bias to the left side of their bodies.

Thus when dogs were attracted to something, including a benign, approachable cat, their tails wagged right, and when they were fearful, their tails went left, Dr. Vallortigara said. It suggests that the muscles in the right side of the tail reflect positive emotions while the muscles in the left side express negative ones.

While some researchers have argued that only humans show brain asymmetry — based on the evolution of language in the left brain — strong left and right biases are showing up in the brains of many so-called simpler creatures, said Lesley Rogers, a neuroscientist who studies brain asymmetry at the University of New England in Armidale, Australia.

Honeybees learn better when using their right antenna, she said. Male chameleons show more aggression, reflected as changes in body color, when they look at another chameleon with their left eye. A toad is more likely to jump away when a predator is introduced to its left visual field (right brain/fear). The same toad prefers to flick its tongue to the right side when lashing out at a cricket (left brain/ nourishment).

Chicks prefer to use their left eye to search for food and right eye to watch for predators overhead, Dr. Rogers said. But when chicks are raised in the dark, they do not develop normal brain asymmetry. In trying to eat and watch for hawks overhead, such nonlateralized chicks become confused and vulnerable to attack.

Sheep, which are good at recognizing individual faces, use the right sides of their brains for knowing a Dolly from a Molly.

Chimpanzee brains are asymmetrical in the same ways as human brains, said William D. Hopkins, a researcher at the Yerkes National Primate Center and psychologist at Agnes Scott College in Atlanta. When chimps are excited, they tend to scratch themselves on the left side of their bodies, reflecting strong negative emotions, he said. And left-handed chimps are more fearful of novel stimuli than right-handers. Their dominant right brains may make them more cautious.

Brain asymmetry for approach and withdrawal seems to be an ancient trait, Dr. Rogers said. Thus it must confer some sort of survival advantage on organisms.

Animals that can do two important things at the same time, like eat and watch for predators, would be better off, she said. And animals with two brain hemispheres could avoid duplication of function, making maximal use of neural tissue.

The asymmetry may also arise from how major nerves in the body connect up to the brain, said Arthur D. Craig, a neuroanatomist at the Barrow Neurological Institute in Phoenix. Nerves that carry information from the skin, heart, liver, lungs and other internal organs are inherently asymmetrical, he said. Thus information from the body that prompts an animal to slow down, eat, relax and restore itself is biased toward the left brain. Information from the body that tells an animal to run, fight, breathe faster and look out for danger is biased toward the right brain.

In this way, Dr. Craig said, animals are naturally designed to cope with changing environments.

bu-bu queries:

Will Toaster like his new countertops? Will black show off his chrome?

Keith Olbermann’s $4.2M Apartment

Moving is stressful, regardless of how many balconies candelabra will have.

Black countertops won’t show Toaster’s dirty little footprints. Bwana is always after him to wipe his feet off before he goes back up on the counter, but does he listen?

Personally, I’m partial to the west side, but we go where Bwana goes. We vow to not let him get all Donald Trump-ish.

Bwana has promised that Toaster will get his own bedroom where he can keep all his little friends. They’ll get their own bathroom, too, which will be good because Bwana is tired of having to share the master bathroom with the Tofu Guys. (If you don’t keep them moist they dry out and get very cranky.) Toaster is also looking forward to having three balconies from which to launch Flaming Tater Tots. We hope the nice police people on the east side are as understanding as the ones in our old neighborhood.

toaster-moving-day-trauma.jpgWe have to plan this move better than the last one. The last time Bwana was supposed to carry Toaster over to the new place, but he got busy and the movers put Toaster in a box and sealed it up. He cried all the way over in the moving van, which kind of freaked out the driver.

This time Grammie will come over and take Toaster to the new place in a limo.

rc writes in Hoodie Mojo:

bwana needs a pinstriped hoodie. the yankees need as much mojo as they can get

Toaster likes the Mets’ ninja hoodies:

The Yankees need more than mojo. They need pitching.

Sheila inquires relative to It Ain’t Over ’til the Fat Toaster Sings:

What’s with the Viking Helmet on Toaster?

Is he into Opera now?”

Toaster says don’t count out the Buckeyes against the Wolverines this year!

It ain’t over ’til the fat lady sings

And yes. He does like the opera:

This maybe Michigan’s year to Beat the Buckeyes.

First…Troy Smith, 17 Seniors, and 3 Juniors are headed to the NFL and those are a lot of spots to fill. And Second the ‘Big Game’ will be played in ‘That State Up North’ this year.

But one should never discount Coach Jim ‘The Sweater Vest’ Tressel.

Hoodie says Coach Jim should wear a Coach Belichick hoodie for an extra dose of mojo. The combination of Hoodie Mojo and Sweater Vest Mojo is very potent.


But Coach Jim would have to lose the tie. Ties cancel out the Hoodie Mojo effect.

Blue Velvet on Are We Ready For Some Football?

Re: the Hoodie

Charcoal would be a good color for Bwana.

Toaster wants Bwana to get his hoodie monogrammed with “KO” just like Coach Bill has “BB” on his. Hoodie says Bwana has to have the sleeves chopped off for it to be truly authentic, but Toaster doesn’t want Bwana’s arms to get cold. Hoodie said this is where layering comes in.

Toaster said Bwana has a lot of nice ties that would go with the charcoal hoodie, but Hoodie said that they aren’t meant to be worn with ties. In fact, if Bwana wore a tie with it then all the Hoodie Mojo would go down the tubes.

rrgirl: there can be a fine line between cute and creepy. I sure hope the kids got some yummy treats and an hour or two to run around on the grass without a four-count in the back ground or a camera in the sky.

To the best of our knowledge no wee Ohioans were injured in the filming of St. Thomas the Apostle Students do Script Ohio. All subjects were fully informed of their rights as well as any potential hazards, and consent forms were signed by all participants.

Be afraid, Michigan. Be very afraid ….
