The university that cloned the first mammal is now investigating why some older dogs — especially those in colder climes — sometimes experience limp tails.
A study at Edinburgh University in Scotland says the phenomenon known as ‘limber tail,’ which causes a dog’s tail to become limp and difficult to move, tends to affect larger working breeds, and is more common among dogs who live in the north.
The study of dozens of dogs found that the chance of a dog developing the condition rose by 50 per cent for each additional degree of latitude further north he or she lived.
Working dogs, who spend more time outdoors, and those who enjoy swimming were also around five times more likely to develop “limber tail,” which is also known as “cold tail” or “swimmer’s tail.” More informally, the condition is sometimes referred to as a dog “losing their wag.”
Personally, we like the name a Telegraph headline writer gave the condition: Erect-tail dysfunction.
No, this is not The Onion you’re reading, and this is not a joke — at least not to the dogs who get it. Owners report that it can be very painful and distressing for the dogs.
“We were surprised by how many owners were reporting limber tail to us but it meant we had the chance to do a detailed investigation,” said Dr. Carys Pugh, of The Roslin Institute and Royal Dick School of Veterinary Studies.
The Royal Dick School of Veterinary Studies, commonly referred to as the Dick Vet, is no joke, either. It’s the veterinary school of the University of Edinburgh.
Dolly the sheep, the world’s first mammal clone, was born at the Roslin Institute in 1996, marking a new era of biological control. Nine years later the cloning of dog — the 18th species successfully cloned — was achieved by scientists in South Korea.
Those affected by limber tail were more likely to be working dogs, and more likely to regularly swim.
The condition, which was first reported in the scientific press in 1997, is thought to affect around 60,000 dogs in Britain, “but owners often struggle to find out what is wrong with their pets as there is little literature available,” the Telegraph reported.
It’s generally not a lifelong condition; rather, it resolves itself within a few days or weeks.
The researchers hope further studies will identify genes associated with the condition, which could one day help breeders to identify animals that are likely to be affected.
Caroline Kisko, Secretary of Kennel Club, which funded the research through its charitable trust, said owners should be careful not to over-expose their dogs to the cold.
“The condition is rare, but is it most often seen in working dogs such as Labrador retrievers, flat coated retrievers and pointers. Dogs usually recover their normal tail posture and function over a period of days or weeks, however it can be painful.”
Gudrun Ravetz, junior vice president of the British Veterinary Association warned owners not to become so worried about the cold that they stop exercising their pets.
“Limber tail is rarely seen in veterinary practices and the research indicates that most owners do not seek veterinary attention for this problem,” she said.

Seems like Ace and I, as we keep piling on the years, take turns these days experiencing health problems — from the pesky to the potentially fatal.
Saturday was his turn again.
He woke me up about 5:30 a.m. to be let outside, not all that unusual. But then he declined to come back in. He just wandered about the backyard, stopping here and there, straining to pee, but to no avail.
Once he did come back in, he wanted out again two minutes later, where he again attempted, unsuccessfully, to complete the task.
As I do with my own ailments, I got on the Internet to Google the possibilities — urinary tract infection, stones of some sort, or some other kind of obstruction that was blocking him from doing what he needed to do.
Given it was already 10 a.m. when I called his vet, and that they close at noon on Saturday, I wasn’t too surprised when I was told all slots were filled. But I was promised that a vet would call me back.
When he did, about 30 minutes later, I told him Ace was struggling to pee and that, to my knowledge, he hadn’t been able to all morning. Otherwise, he seemed fairly normal, and not in pain, not even when I pushed and prodded around his abdomen.
The vet — not the one I usually see at the practice — told me that, while I might have to wait around for an opening, I could bring Ace in. And he told me I probably should. If I waited until Monday, and Ace went all that time without peeing, he’d likely be dead by then.
After taking some X-rays, the vet showed me what he said were bladder stones — faint little circles, and some not so little, inside his bladder. He said it would take some testing to determine which kind of stones they were (some are more easily treated than others). The first priority though, was to get that obstruction cleared and that bladder drained, so he suggested a catheter.
I winced at the word. It has only been a few months since I was treated to that process while in the hospital for bypass surgery. Of all the highly intrusive things they did to me (okay, for me) the installation of the catheter remains my most traumatic memory. The mere word gives me shivers.
Why, I wondered then, and still do, would they install this device into a person without knocking him out — good and out — first?
I would not wish it on my worst enemy, much less my best friend.
Ace, his tail tucked between his legs rather than in its normal full and upright position, was ushered to a back room, and I stepped outside to pace and worry. I didn’t exactly “feel his pain,” but I did remember mine.
As soon as I stepped back into the office, only about five minutes later, the vet and a technician came into the waiting room with Ace and said things were flowing again. Ace, thanks to the catheter, had peed, and peed some more, and one little stone came out in the process.
The vet tech took Ace outside and he peed some more. His curled-up tail, which had been in the down position all day, was up — generally a sign that all is right with the world, or at least his world.
While the emergency was over, the ailment remains. Tests of his urine this week will determine whether the stones still inside his bladder are of the struvite variety, which can sometimes be treated with a therapeutic diet, or calcium oxalate stones, which require surgical removal to totally get rid of them.
Whatever the case, I’m sure Ace will handle what’s ahead in a far more classy and stoic manner than I would.
These days, we both grunt a bit now when settling down, or getting up. We’re both a little slower. We both have to shift around a bit to get comfortable, then stretch ourselves out when we get back up again.
But somehow he is better at this aging thing than me. It has been almost three years since he, now 10, surpassed me, now 61, according to most formulas for comparing dog years to human years. Now, as a large dog, he’s aging much more quickly than I am — even though you wouldn’t know it to look at us.
This week’s medical agenda includes the testing of his urine, whatever steps are deemed necessary for him after that, an echocardiogram on me to assess how my heart is working after quintuple bypass surgery, and another visit to my physical therapist for a continuing back and shoulder problem, now being treated by something called “dry needling.”
I’ll spare you the details of that. Suffice to say, for me — and even for my dog — getting old is getting old.
(A special thanks to Brian LeFevre at Winston-Salem’s Ard-Vista Animal Hospital for working Ace into his schedule and getting things flowing again.)

Dog blogger and broadcaster Steve Friess says he’s not going to spend $5,000 to put his dog though chemotherapy that could extend his life a year or more — and he’s going to try not to feel bad about it.
Even when he says his final goodbye to Jack in what could be less than a month.
In late October, Friess noticed the dog he’d adopted nine years ago was getting lethargic, and that his weight had dropped from his usual 11 pounds to around eight.
A vet diagnosed that Jack had an aggressive form of lymphoma that was spreading quickly through his body.
Friess did some research, checking with friends, and vets, and friends who were vets: One of the latter urged him to “do the full chemo protocol ASAP!” It could send Jack into remission for nine months, or 12 months, or even longer.
Friess and his partner researched, debated and decided against chemotherapy — not because it would be all that rough on the dog physically (they handle it much better than we do). The main reason, he admits, is the money, which, he also admits, they just doesn’t have.
There will likely be those who second guess Freiss, or maybe try to lay a guilt trip on him: Take out a loan, hit up your friends, get a second (or third) job, launch an online fundraising campaign, let me be the first to donate.
We’ve become a nation of such overflowing compassion for dogs, with such promising new medical technologies, and such handy online fundraising tools at our beck and call, that it’s easy to lose sight that decisions about life and death — both ours and our dogs — are still our own, and that throwing in the towel, for financial reasons, or others, isn’t always a shameful choice.
We suspect Friess will receive some support for his decision, but will hear from many more questioning it. His decision to write about it, as he did in a post for Time.com, is brave, but also an open invitation to second-guessers. In any case, the decision on what’s best for Jack should be (and has been) made by the person who knows him best, and deserves to be respected
Friess, a freelance writer and co-host of The Petcast, said neither his advisers nor his vet seemed to be trying to make him feel guilty about his choice. But, as is the way with guilt trips, we often don’t need a tour guide. Feelings of shame can start as soon as we ask our vet the question Friess did:
“How much will it cost?”
For Friess, the estimate was a minimum of $5,000 — more than he and his partner had.
“(It) means we have about 30 days. The end will probably come in time for holidays … “We’ve received a lot of advice, both solicited and unwelcome, through social media. Nobody comes right out to say it, but the disappointment some express at our decision shows that they question our love for Jack. In an era when people spend big on animal clothes, artisanal foods and medical intervention, and when medical science makes it possible to spend $5,000 so Jack dies slightly later than sooner, there is pressure to go as far as we can.”
There’s one more twist. Friess and his partner are trying to adopt a human baby, and they’re working on saving the $15,000 fee for that.
“If that $5,000 could cure the cancer and restore Jack’s full life expectancy, maybe we’d do it,” he wrote. “Maybe. It certainly would be a tougher choice. But to buy a year during which we’d be waiting for his lymph nodes to resume their swell? We could endure the end stages either now or later.”

Gregory Berns, a professor of neuroeconomics at Emory University, has been able to scan the brains of a dozen dogs using an M.R.I, which is quite an achievement in itself. But in looking at those scans he says he has reached the conclusion that, “Dogs are people, too.”
“The ability to experience positive emotions, like love and attachment, would mean that dogs have a level of sentience comparable to that of a human child,” he wrote in an op-ed piece that appeared in Saturday’s New York Times. “And this ability suggests a rethinking of how we treat dogs.”
Berns’ research, which started with his own adopted dog Callie, is detailed in his soon to be released book “How Dogs Love Us: A Neuroscientist and His Adopted Dog Decode the Canine Brain.”
Bern set out to determine how dogs’ brains work, and what they might be thinking. To that end, he began training dogs to undergo — and stay still during — M.R.I. scans, willingly and while awake and unrestrained.
“Conventional veterinary practice says you have to anesthetize animals so they don’t move during a scan. But you can’t study brain function in an anesthetized animal,” he notes. “At least not anything interesting like perception or emotion.”
Initially, he worked with his own dog, Callie, a black terrier mix he adopted from a shelter, using a simulated M.R.I. he built in his living room. As word spread about his research, others volunteered their pets and Berns soon had a dozen dogs “M.R.I.-certified.”
“After months of training and some trial-and-error at the real M.R.I. scanner, we were rewarded with the first maps of brain activity. For our first tests, we measured Callie’s brain response to two hand signals in the scanner. In later experiments, not yet published, we determined which parts of her brain distinguished the scents of familiar and unfamiliar dogs and humans.”
Berns and his team focused on a key brain region called the caudate nucleus, which sits between the brainstem and the cortex. In humans, the caudate, rich in dopamine receptors, plays a key role in the anticipation of things we enjoy, like food, love and money. Same with dogs — except, we’re pretty sure, for the money part.
“Specific parts of the caudate stand out for their consistent activation to many things that humans enjoy,” he says. “Caudate activation is so consistent that under the right circumstances, it can predict our preferences for food, music and even beauty … In dogs, we found that activity in the caudate increased in response to hand signals indicating food. The caudate also activated to the smells of familiar humans. And in preliminary tests, it activated to the return of an owner who had momentarily stepped out of view.”
Berns believes the scans will tell us more than behavioral observations do about what dogs are thinking.
“Do these findings prove that dogs love us? Not quite,” Berns wrote. “But many of the same things that activate the human caudate, which are associated with positive emotions, also activate the dog caudate.”
That “functional homology,” as neuroscientists call it, may be an indication of canine emotions.
And given that, he asks, is it time to stop considering them property and start affording them some rights as individuals?
“If we went a step further and granted dogs rights of personhood, they would be afforded additional protection against exploitation,” he says. “Puppy mills, laboratory dogs and dog racing would be banned for violating the basic right of self-determination of a person.”
That day may not be directly around the corner, he notes, but with more being learned about how their brains work, and what thoughts run through them, it could eventually arrive.
“Perhaps someday,” he says, “we may see a case arguing for a dog’s rights based on brain-imaging findings.”

Tai, the 42-year-old Asian elephant who stars in the new movie “Water for Elephants” may not have been harmed in the making of that particular film — but he learned the tricks he does in it by being repeatedly shocked with electricity, an animal welfare organization says.
Animal Defenders International said a six-year-old video of Tai being trained has been posted on the Internet, shows trainers administering electric shocks as they teach him tricks.
“Water for Elephants,” a romantic drama set in a 1930s-era American circus, stars Reese Witherspoon and Robert Pattinson. It is premiering this month.
Tai, supplied by Have Trunk Will Travel of California, plays the role of Rosie, an elephant who is brutally attacked with a bull hook by by the circus owner.
The American Humane Association monitored production of the movie — and it, as well as the producers, stars, and trainers have said Tai was treated with nothing but kindness during the movie’s making.
A representative of the American Humane Association stated during the making of the movie, “all these animals have been treated fairly and humanely throughout the entire course of their training.”
Gary Johnson, a founder of Have Trunk Will Travel claimed: “Tai was never hit in any way at all,” according to ADI.
ADI, however, says video filmed at Have Trunk Will Travel in 2005 clearly shows Tai being shocked as part of his training.
Jan Creamer, Chief Executive of ADI said: “We were uncomfortable with the message of this film, but the more we saw the repeated assertions that this elephant has been treated with love and affection and never been abused, we realized that we had to get the truth out. The public, the stars and the filmmakers have been duped. This poor elephant was trained to do the very tricks you see in the film by being given electric shocks.”
ADI said it was sending copies of the video to the film’s stars and makers.
“I believe that Reese Witherspoon and Robert Pattinson will be horrified to learn what Tai went through,” Creamer said.
ADI has also contacted American Humane Association, urging them to re-evaluate how they assess the use of animals in films. ADI is also calling for a boycott of the film.

Patrick, the dog found starved nearly to death after he was dumped down a high-rise apartment building’s trash chute in Newark, now weighs in at more than 35 pounds.
And that’s without the petrified hairball that was surgically removed from his stomach this week.
Dr. Jason Pintar, an internist at Garden State Veterinary Specialists, removed the long flat hair mass from Patrick’s stomach using a video endoscopic procedure while Patrick was under anesthesia.
After the hair mass was removed, Patrick was transferred to another surgery suite for neutering, Associated Humane Societies in New Jersey reportsAfter surgery, he’ll still need treatment for mange, and physical therapy for weak rear legs, AHS says.
The non-profit organization says it’s receiving thousands of emails a day — and that it has been contacted by several people who say Patrick was their dog. Some say he ran away, some say he was stolen, and one told AHS they’d contacted an attorney.
Also casting a cloud over Patrick’s story is the emergence of people hoping to profit off his name and image.
The number of Internet sites related to him — some well-intentioned, some not — has steadily grown, and some are selling “Patrick” items such as t-shirts, keychains and posters, and using his story to “solicit funds for their own use,” AHS says.

No, not in the manner you might assume. I am refraining from sharing his stash. Nevertheless, I have calmed down – because he has calmed down.
When I get on the floor next to him, or even glance at him there, it’s as if the drug is somehow passing into me. Seeing him more comfortable makes me more comfortable, just as hearing his yelps put me on edge.
By way of background, I took Ace, 6, to the vet last week after, a few days earlier, he began yelping every time he made a sudden motion. A herniated disc was the diagnosis, and the course of action recommended by the vet was NSAIDs to relieve the inflammation and doggie valium — Diazepam to be precise — to keep him unnaturally calm during the two weeks of bed rest prescribed.
I’ve heard of some negative side effects associated with NSAIDs and dogs, and I’ve never been big on pharmaceuticals that mask symptoms and alter moods, but the conservative – and least expensive – approach struck me as worth trying first.
The effect was almost immediate. Ace had been restless, pacing slowly and holding his head carefully, as if anticipating another burst of pain. His tensing up made me tense up, which made him tense up more, which made me tense up more.
It’s a phenomenon I’ve noticed before – how our emotions and moods tend to play off each other and snowball.
Say a big scary bug comes in the house. I, upon seeing it, will jump up and reach for a magazine, shoe, or other instrument of death. Even before I jump up, though, Ace, even if he hasn’t seen the bug, mirrors my startled (assuming the bug is scary enough) reaction, almost as if he can sense, like a pending earthquake, my heart rate increasing from the other side of the room.
There’s a kind of emotional synchronization that occurs between dog and owner – and maybe it’s true of any two beings that co-reside, even spouses.
In our duality, we find a oneness, to the point we think we can read each other’s minds – and often we react based on that.
When Ace is happy, which is usually, it makes me happy, which makes him even happier, which makes me even happier. One of the things at the root of our love for dogs, I think, is that spiraling contentment and joy. Of course, the same is true, at least with Ace and me, when dog or human are unhappy.
Our dogs are a reflection of us, and we are a reflection of our dogs.
This reflection stuff gets reflected on a lot in my book, “DOG, INC: The Uncanny Inside Story of Cloning Man’s Best Friend,” which recounts the history of cloning dogs and its emergence as an industry that, in the view of critics, exploits the grief of bereaved pet owners.
One of the reasons losing a dog is so tough – on top of it bringing an end to all that respect and admiration we see in their eyes, all that loyalty and unconditional love – is, I think, that we see ourselves in them.
Cloning our dogs – as some people are doing – is not just a futile attempt to skirt death, but also, it can be argued, an attempt to recapture one’s own youth, via a puppified version of their own dog. When the old mirror dies, we can get a new, genetically identical one – one that looks exactly the same, but has the added benefit or making us feel younger when we look into it.
How dogs reflect their owners is the subject of another new and fascinating book, “Your Dog is Your Mirror,” which we will get around reviewing soon. (Those of you who visit ohmidog’s dog book page may have noticed it’s a bit behind, and doesn’t even include my book.)
Written by dog trainer Kevin Behan, “Your Dog is Your Mirror,” puts forth the theory that a dog’s behavior is driven by its owner’s emotions — that dogs respond to what their owner feels, even when the human isn’t aware they are feeling it. Behan says dominance – or being the pack leader — is not the key to dog training. Instead, it’s understanding what emotions you, the human, are passing on to the dog.
It’s the heart — more than dominance, treats or anything else — that connects dogs and humans.
For now, controlled substances are giving us a hand, providing Ace and me with a symbiotically snowballing sense of serenity. Yes, it’s somewhat artificial. And yes, I worry that the drugs will make him feel better before he actually is, leading him to attempt things he shouldn’t attempt.
So we are staying mostly in our current temporary lodgings — a mansion basement in North Carolina. He is under orders not to romp. So I shan’t romp, either. Instead, we’ll limit our outings. We’ll pop the occasional pill. We’ll read, and watch TV, and watch each other, the way we do, having plenty of time for some quiet reflection.
