I’ve got to admit I’ve never paid much attention to which way Ace’s tail is wagging — mostly to the right, or mostly to the left.
More often, it just seems to go back and forth, one side to the other, which is kind of the definition of wag.
But researchers in Italy, who first reported that the prominent direction of the wag signifies whether a dog is experiencing positive or negative feelings, now say other dogs are aware of this subtle distinction, and apparently have been for some time, indicating they — dogs — are much more on top of things than researchers.
Researchers at the University of Trento, in a new study, had dogs watch videos of other dogs wagging their tails. They found, according to a study reported in the journal Current Biology, that dogs watching another dog whose tail is wagging left showed signs of anxiety, including a higher heart rate. When watching a tail wag right, they remained calm.
When watching “Two Broke Girls” the dogs asked if they might please leave the room. (Not really.)
Returning to seriousness, the Italian researchers first reported in 2007 that dogs convey a wide array of emotions through the tail wag — not just happiness. A wag to the left indicates negative emotions; a wag to the right indicates positive ones. The directions are as seen when standing behind a dog.
In the earlier study, 30 dogs were placed, one at a time, in a large box surrounded with black plastic to prevent any visual stimulus (except maybe to dogs who find black plastic stimulating). The dogs were then shown a stimulus for 60 seconds — a dominant Belgian Malinois, a cat in a cage, their owners, and a strange human, by which we only mean one they hadn’t met.
A system for measuring the tail movements of each dog was established — far too complex to go into here. Suffice to say, as the scientists put it:
“Tail wagging scores associated with the different stimuli were analyzed from video-recordings. Positions of the tail were scored every 10 seconds by superimposition on the computer screen of a cursor on the long axis of the body: the maximum extents of the particular tail wag occurring at each 10 second interval was recorded. Using single frames from video recording two angles were identified with respect to the maximum excursion of the tail to the right and to the left side of the dog’s body. Tail wagging angles were obtained with reference to the axes formed by the midline of the dog’s pelvis – the segment extending lengthwise through the dog’s hips, drawn from the largest points as seen from above and the axes perpendicular to it.”
When faced with their owner, dogs exhibited a “striking right-sided bias in the amplitudes of tail wagging.” Less robust right-sided wags were observed also when the dogs were shown unfamiliar humans. When faced with a cat, dogs showed very reduced tail wagging, but still a slight bias favoring the right side. Seeing a dominant unfamiliar dog led the dogs in the study to wag more to the left.
The first study reported: “How far asymmetric tail-wagging responses are associated with postural asymmetry in preparation to the stimuli is difficult to say.” (You can say that again) “It is likely that control of the flexure of the vertebral column is the same for the tail as well as the rest of the column, but the method we used for scoring tail-wagging responses and the panels flanking the body of the animal in the test-cage minimized any effect of asymmetric posture associated with spine bending.”
I’ve got to wonder which way the dogs’ tails wagged — or if they tucked them between their legs — when they were listening to the scientists talk.
The researchers stop short of saying wagging tails are a mode of communication between dogs.
“This is something that could be explained in quite a mechanistic way,” said Giorgio Vallortigara, a neuroscientist and an author of both studies. “It’s simply a byproduct of the asymmetry of the brain.” Dogs, he explains, have asymmetrically organized brains, like humans (or at least most of them): ”The emotions are associated presumably with activation of either the right or left side of brain,” he said. “Left-brain activation produces a wag to the right, and vice versa.”
But it would seem to me that if one dog is moving his tail, and another is drawing conclusions from that motion, as the scientists say is the case, that’s communication — perhaps even a clearer form thereof than that to which the scientists are prone.

When the Cathedral of Saint John the Divine decided it needed to do something about the increasing numbers of dogs pooping on its hallowed grounds, it turned not to a deity, but to a design firm.
That firm’s answer? A series of signs, using Old Testament verse as an inspiration, along with regular English, in smaller print, for those who might not get it.
The Episcopal church, something of a landmark in New York City, isn’t totally down on dogs. It hold a blessing for dogs and other creatures on St. Francis Day. And it doesn’t mind that it has become a popular spot with dog owners. It just didn’t like the mess.
The design firm Pentagram says the church didn’t specifically request humorous signs, but that seemed to be the best approach.
The signs read, “Thou shalt not poop (Please keep dogs off grass),” ”Hold close thy loved (Please keep dogs on a leash),” and “Collect what you receive (Please clean up after your dog).”

Citywide pit bull bans are often knee jerk reactions — maybe even more so when a county sheriff”s knees are involved.
One week after Jefferson County Sheriff Mike Hale was approached in his yard by four dogs “acting aggressive and looking like pit bull breeds” — and fired a shotgun at them, grazing one — the Alabama city of Clay passed a “vicious dog” ordinance banning pit bulls and pit bull mixes.
The sheriff, according to a spokesman, fired a warning shot into the ground, then another round of ”bird shot” in the direction of the dogs, leading them to turn away. Animal control arrived to round up the dogs, and their owner was charged with letting them run at large. The dog hit by Hale’s shot survived, AL.com reported.
That incident prompted the city council in Clay, with a speed seldom seen in government affairs, to pass an ordinance banning pit bulls and other “vicious” or “dangerous” dogs.
The ordinance bans new pit bulls and mixes that include pit bull. Such dogs already kept in the city limits are grandfathered in but must be registered with the city in the next 60 days. The ordinance requires they be kept indoors and mandates owners post a prominently displayed ”beware of dog” sign. Owners are also required to have $50,000 in liability insurance. Violations can be punished with a fine of up to $500 and up to 30 days in jail.
Having sought little public input before passing the law on June 3, the city council has gotten some since, AL.com reports.
A standing room only crowd filled Monday night’s meeting of the Clay City Council, with most citizens arguing the breed is not “inherently dangerous” and criticizing the law for unfairly penalizing responsible owners. Many, including a representative from the Birmingham Humane Society, urged the council to consider a non-breed specific dangerous dog law instead.
One speaker continued to voice his concerns after his turn to speak was over. When told he was interrupting, he continued his comments, leading Mayor Charles Webster — perhaps deeming him to be inherently dangerous — to ban him from the room.
“You are turning us all into criminals,” the man, identified as Mark Lawson, said as a deputy led him outside.
City Attorney Alan Summers said he would try to have a new or modified ordinance for the council to consider at its next meeting on July 1.

It’s dark down here. Even with every light on, even when the sun’s up, the temporary home Ace and I have landed in — a cellar apartment in an old southern mansion — is, given its subterranean location, something less than bright and cheery.
I have window wells, but little light shines through. I look out and assume it’s a rainy day — only to step outside and see that it’s as sunshiny as it can be. Down here, it’s as if it’s always 3 a.m. Ace wakes up, looks around, and — like me — assumes it’s not morning yet.
I haven’t been cursing the darkness. That’s best reserved for internet connections. But I think it has been keeping me from being awake as I might be, and I haven’t gotten a lot of writing done. Instead I’ve mostly been oversleeping, setting up housekeeping and visiting my mother. She lives about a mile down the road, so Ace and I have visited almost nightly — conveniently around dinner time. I mentioned to her how dim things were in my apartment, and she, being a former newswoman, felt the need to share that — at least with my sister.
I’ve introduced you to my sister before, when Ace and I passed through Madison, Wisconsin. She’s prone to random outbursts of karaoke singing, sermonizing, deep thoughts and good deeds, and I was about to be a recipient of one of them — luckily the latter.
She called to tell me she had found four lamps on Craigslist, and that she was giving them to me as a Christmas present. All I had to do was drive to some town called Midway, and find the home of a man named Ken. She sent me an email with the directions. Like all her emails, it ended with the same quote from Edith Wharton: “There are two ways of spreading light: to be the candle or the mirror that reflects it.” (Buying lamps via Craigslist wasn’t an option in Edith’s day.)
I popped open the back window of the jeep. He greeted Ace, noticed there was no air in the tires of my bicycle, still attached to the rack, and offered to pump some in. He helped me load the four lamps into the car, and told me to help myself to the kitchen items packed in boxes in his barn. They, like the lamps, had belonged to his mother, who died last fall at age of 98.
I tried to pay Ken $60 — $48 for the lamps, the rest for everything else I grabbed – but he insisted on giving me change. I stuffed as much as I could into the car — or at least as much as Ace would permit. Ace doesn’t like things rattling around back there, or any of the contents to shift while we’re driving, and given the back seat has been his home for most of the past nine months, I try to oblige.
After loading up, we stopped for lunch in Midway, which is next to a town called Welcome, at a place called The Dawg House, then headed down the road to the Midway General Store, where it was hard to find things because it was dark inside. But I got three copies made of the key to my new place, bought two plug adaptors, three packages of cuphooks and a big greasy hambone for Ace — all for a mere $11.
Ace nibbled his bone as I took the back roads home, passing church after church — all with marquee signs out front:
‘Hands joined in prayer are never empty,” one said.
“The church is a pit stop in the race of life,” read another.
“God’s plans for us are better than our own,” another advised.
Space being limited on church signs, attribution for the words of wisdom on them is seldom provided — so you never really know whether they come from God, the local preacher, Edith Wharton or some book, like “1001 Catchphrases for Your Church Marquee.”
Whether they are original words, or a reflection of somebody else’s, doesn’t really matter — as long as they are getting shared, because church marquees, even those that don’t light up, are all about spreading the light, giving life some meaning, tossing a little hope, inspiration and joy our way.
On top of that, never having lived in darkness before, I’ve learned that, much like a chili cheese dog, light – the non-symbolic, simple wattage kind — makes me happy.
For Ace, a hambone works just fine.

A friend sent me this photo, taken at the Barnes & Noble in Towson, which shows “DOG, INC.: The Uncanny Inside Story of Cloning Man’s Best Friend” getting some pretty decent display (at least better than the bottom shelf of the astronomy section, as was the case at an area bookstore that shall remain nameless).
I can think of no other sign I would like my book to be under — except maybe ”New York Times Bestseller.”
Alas, it’s not there yet, but it did rate the “Page 99 Test,” a website by Marshal Zeringue dedicated to the proposition that the quality of a book can be judged by turning to, and reading, its 99th page.
I lucked out in that page 99 of “DOG, INC.” contains a revelation — namely who it was that located Genelle Guzman, the last survivor found after 9/11, and held her hand until she could be freed from the mound of debris she was trapped under.
(Clue: It wasn’t the volunteer firefighters who took credit for rescuing her on CNN)
If you’re wondering what this has to do with cloning dogs, you can click the link to Marshal’s blog or, better yet, buy the book and allow your thoughts — and perhaps more — to be provoked.
