Two University of Washington scientists think it might be possible to slow the aging process in canines and are launching a pilot study with 30 dogs to see if the drug rapamycin significantly extends their lifespans.
The researchers, using $200,000 in seed money from the University of Washington, plan to use pets, not laboratory animals, for the initial study, and recruit volunteer dogs — or at least dogs whose owners volunteer them — for larger scale studies in the future.
Daniel Promislow, an evolutionary geneticist, and Matthew Kaeberlein, a molecular biologist, say the study is aimed at determining whether rapamycin could lead to longer lives for dogs — as studies have shown is the case when it’s used on yeast, fruit flies, worms and mice.
“We’re not talking about doubling the healthy life spans of pets,” said Kaeberlein. “But at a minimum I would predict that you would get a 10 to 15 percent increase in average life span, and I think bigger effects are possible.”
In the pilot study, 30 large, middle-aged dogs will be involved — half receiving low doses of rapamycin, half receiving placebos.
The researchers say that subsequent studies will seek to enroll pet dogs from across the country.
Kaeberlein and Promislow hosted a meeting in Seattle last week where experts from across the country discussed the drug rapamycin and its possible effects on the health and longevity of dogs, the Seattle Times reported.
Currently used along with other medications to prevent rejection in organ-transplant patients, rapamycin has been called a promising anti-aging drug — though there have been no studies involving humans.
But almost 50 laboratory studies have shown that the compound can delay the onset of some diseases and degenerative processes and restore vigor to elderly animals, extending life spans by 9 to 40 percent.
Rapamycin functions, in part, by inactivating a protein that promotes cell growth. As a result, cells grow more slowly, which retards the spread of cancer.
Promislow, who has two elderly dogs of his own, noted that even if the drug doesn’t increase the life span of dogs, it could serve to keep them healthy longer. “We’re trying to understand why some dogs age better than others, and help all dogs age in a better way,” he said.
The drug has been shown to have serious side effects, including poor wound healing and an increased risk of diabetes, when used at the high doses required for organ transplant patients.
But the low doses used in anti-aging research with mice and other lab animals cause few side effects.
There have been no large-scale human trials. Studying how the drug affects dogs — who suffer many of the same old-age ailments as their masters — makes it possible to explore the possible benefits of rapamycin both more quickly and at a lesser cost.
If it does turn out to be a sort of fountain of youth — for dogs, humans, or both — the potential profits would be enormous.
“I think it’s worth a go, not just from what it can teach us about humans, but for the sake of the animals themselves,” said University of Alabama Biology Department Chairman Steven Austad, an expert in aging research who is not involved in the project. “It may not work in dogs, but if it did, boy, it’s going to be huge.”
According to the Seattle Times article, drug companies aren’t very interested in rapamycin because it’s no longer under patent.
But the researchers are hoping dog lovers, dog-food companies and some foundations might be willing to contribute to further research.
They’ve set up a website, dogagingproject.com,where people can donate and sign their dogs up to take part in the research.
“Given how I feel about my pets, I see this as a unique project where there’s a real potential for citizen science,” Kaeberlein said. “I think it would be great if pet owners who are really interested in improving the health of their animals would help fund this work.”

A Houston man who once portrayed McGruff the Crime Dog has been sentenced to more than 16 years in prison on drugs and weapons charges.
John R. Morales was sentenced to federal prison last week for charges related to his 2011 arrest.
Police who raided Morales’ residence then seized 1,000 marijuana plants and 9,000 rounds of ammunition for 27 weapons — including a shotgun, pistols, rifles, and a military grenade launcher, according to court documents obtained by NBC.
What does all this prove? If you want mascot who is pure, ethical and beyond reproach, choose a real dog. They are far less likely to get arrested, far less likely to cause a scandal, and far less likely to cave in to temptation, unless they are of the bacon variety.
This wasn’t the first time the choice of a human to play McGruff has come back to bite law enforcement. There was an incident in Phoenix in 1998 when a prison trusty police assigned to play the role removed his head and was recognized by parents in the audience as a convicted child molester.
Morales wore the McGruff costume for the Harris County Sheriff’s Association in the late 1990s. Fox News reported.
The human-like, trench coat-wearing dog was created by the global advertising agency Saatchi & Saatchi through the Ad Council for the National Crime Prevention Council to increase crime awareness among children.
He appeared on television in animated form, and in public appearances he was portrayed by actors wearing the giant dog head and costume.
He urged young people to “take a bite out of crime.”
Morales, after his McGruff gig, was stopped in 2011 by police in Galveston for speeding, and marijuana was detected in his car trunk. Authorities said that, in addition to marijuana plants, they found a clipboard with diagrams of two indoor pot farms in his car.
That led officers to a stash of 1,000 marijuana plants and the weapons.
And who was it that first detected the marijuana in the car? A real police dog.

What’s a working dog to do? You learn your trade, hone your skills, toil away, only to find out that the world around you has evolved to a point where those skills are no longer much appreciated.
It’s why you can’t find a blacksmith too easily nowadays. It’s what happened to the elevator operator, the milkman, and, at least from my biased and disgruntled point of view, the newspaper reporter.
Such too was the case with Phelan, a marijuana-detecting Labrador retriever in the employ of the police department in Lakewood, Colorado.
With the passage by Colorado voters of Initiative 502 — legalizing the recreational use of small amounts of marijuana — the skill Phelan was best known for is no longer much in demand there.
In fact, his biggest asset has become a liability, the News Tribune reports.
Phelan was handed his pink slip this week and sold to the state Department of Corrections, where, in his new job, his inability to distinguish between marijuana and other drugs won’t be a problem — all drugs being illegal behind bars.
The same story is playing out in Washington state, where voters also legalized marijuana use, and where police departments are figuring out whether to cease training new dogs in marijuana detection, put their existing dogs through ”pot desensitization” training or just retire them and send them out to pasture, according to the Associated Press.
Take it from me, pasture sucks. Dogs and people, I think, prefer having a mission.
But Phelan’s mission, at least in the two states where moderate amounts of marijuana are now permitted, no longer much needs to be accomplished. Worse yet, alerting to small amounts of marijuana could mess up prosecutions in cases involving other, still illegal, drugs.
Say Phelan alerted to drugs in the trunk of a car. Phelan’s inability to distinguish between heroin and marijuana — or at least specify to his handler to which he is alerting — means any subsequent search by officers could have been based on Phelan detecting an entirely legal drug, in an entirely legal amount.
That means the “probable cause” the search was based on might not have really existed, and that means any evidence of illegal drugs subsequently found in the search would likely be tossed out.
Thus Phelan, unless he were to be retrained to drop marijuana-detecting from his repertoire — not easily accomplished — has ended up going from cutting edge law enforcement tool to an old school has been.
Drug detecting dogs — traditionally trained to alert to the smell of marijuana, heroin, crack cocaine, methamphetamine and cocaine – can’t specify what they’re smelling, much less the quantity it might be in.
In Washington, the new law decriminalized possession of up to an ounce of the drug for individuals over 21, and barred the growth and distribution of marijuana outside the state-approved system.
Dog trainer Fred Helfers, of the Pacific Northwest Detection Dog Association, said abandoning pot training is a “knee-jerk” reaction: “What about trafficking? What about people who have more than an ounce?” Still, he’s helping departments who want to put their dogs through ”extinction training” to change what substances dogs alert to. That takes about 30 days, followed by a prolonged period of reinforcement.
The Washington State Criminal Justice Training Commission removed detecting marijuana from its canine team certification standards this year, and no longer requires dogs be trained to detect it, but some others say, given large amounts of pot are still illegal, it can still be a useful skill for a dog to have.
In Pierce County, prosecutor Mark Lindquist believes new dogs are the answer — dogs trained in sniffing out the other drugs, but not marijuana. He’s not convinced dogs can be re-trained. “We’ll need new dogs to alert on substances that are illegal,” he told the Associated Press.
Other police departments, like Tacoma’s, aren’t making any changes.
“The dog doesn’t make the arrest, the officer does,” said spokesperson Loretta Cool. “A canine alert is just one piece of evidence an officer considers when determining whether a crime has been committed.”
Phelan was one of two drug-sniffing dogs on the police force in Lakewood, Colorado. He’ll be replaced by Kira, a Belgian Malinois who was trained not to alert when she smells marijuana. Duke, a Labrador retriever mix with the old-school training, will remain on the force for now.
Phelan, though, will be moving on, and I sympathize with the crime-fighting Lab.
His new gig in the slammer is clearly a step down the career ladder — not unlike going from being a newspaper reporter detecting corruption and injustice to an unpaid blogger who mostly (but not entirely) regurgitates material already written.
And, for Phelan, there’s the added insult of being sold for the lowly sum of one dollar.
Surely — old school as his talents may be – he was worth more than that.

This ad for Trifexis depicts a dog living in a bubble — albeit it one that’s outside and has plenty of tubes to run around in.
It serves to protect him from heartworms, hookworms, roundworms, whipworms, flea infestations and all those other frightening hazards that exist in that place where dogs, for centuries, managed to survive:
What we find most interesting about it, though, are the disclaimers, which seem to have risen with doggie prescription drugs to the same level they have with human ones, where three-fourths of the advertisement are devoted to a listing of potential scary side effects, quickly recited in monotone, in hopes you — or your dog — won’t really hear them.
With Trifexis, it goes like this: “Treatment with fewer than three monthly doses after the last exposure to mosoquitoes may not provide complete heartworm prevention. The most common adverse reactions were vomiting, itching and lethargy. Serious adverse reactions have been reported following concomitant extra-label use of ivermectin with spinosad alone, one of the components of Trifexis.”
On top of the warnings recited, more appear in small print during the ad:
“To ensure parasite protection, observe your dog for one hour after administration.”
“If vomiting occurs within an hour of administration, give another full dose.”
“Puppies less than 14 weeks of age may experience a higher rate of vomiting.”
In their print ads, the makers of Trifexis additionally advise the drug be used with caution in breeding females, and in dogs with epilepsy. Its use in breeding males has not been evaluated. Print ads also list lethargy, depression, decreased appetite and diarrhea as possible side effects.
The chewable, beef-flavored tablets — administered once a month – are a combination of spinosad and milbemycin oxime, and they serve to prevent heartworm disease, kill fleas and prevent infestations and treat hookworm, roundworm and whipworm infections.
The tagline for the ad is “You don’t have to go to extremes to protect your dog from parasites.”
Apparently you do, though, if you’re selling prescription drugs — for canines or humans — to protect your ass from lawsuits.

Ralph Ullum, 68 of Claysville, was attending a kennel club show in December at the DuPage County Fairgrounds with his girlfriend, whose Siberian husky, Diana, was entered in the competition.
He’s accused of feeding Protonix and possibly Benadryl to a competing husky, named Pixie, NBC in Chicago reported.
Pixie’s handler, Jessica Plourde of Newark Valley, N.Y., noticed a crushed pink pill near Pixie’s cage on the second day of competition, according to police. Later, witnesses came forward saying they had seen Ullum feeding and petting Pixie while Plourde was away from the cage
A veterinarian induced vomiting in Pixie and found a rubber band, dog food, chicken pieces and an undigested Protonix pill. Protonix is used to treat acid reflux and heartburn. Wheaton police say the pink crushed pill found near Pixie’s cage is believed to be Benadryl, an over the counter allergy medicine that can cause drowsiness.
Ullum denied feeding anything to Pixie, but said he did pet her.
His hearing on misdemeanor cruelty to animals charges is scheduled for June.

The mansion whose basement I’m living in has a big back yard, and in that big back yard is a big swimming pool, covered with a big black plastic tarp.
Ace likes to venture deep into the ivy behind the pool to do his business, and he’s always careful to avoid the pool on his way back.
Yesterday — and I blame the Valium — he didn’t.
As I watched — I’m monitoring him closely because he has been diagnosed with a herniated disc – he finished up and started walking straight for the pool. As I yelled “NOOOOOO!,” or words to that effect, he stepped right onto the black plastic tarp, which, unable to hold his 127 pounds, split, causing him to fall into the pool with a huge splash and disappear.
As far as scary moments in our continuing travels, it was right up there, second only to when, while I was holding his leash, he jumped over the railing at Niagara Falls, landing on a patch of grass that led to a sheer unprotected drop off into misty oblivion.
Fortunately, he jumped right back over then. And fortunately yesterday, his head almost immediately popped back up through the same hole he went through, and it was close enough to the side that he could drape his front paws over the edge of the pool and cling to it with a look of panic in his eyes.
On doggie swim days at Riverside Park back in Baltimore, Ace only went into the big boy pool once, preferring to wade in the baby one. When he did try the big one he was unable to get out. It took me and two friends to hoist him up and over the pool’s edge.
Yesterday, thanks either to adrenalin or the harness he’s been wearing instead of a collar since his diagnosis, I was able to pull him up enough for him to be able to get his back paws on the edge of the pool. I pulled, he pushed, and within a few seconds, he was out.
At that point, either invigorated by the cold and slightly green water, or just happy to be alive, he took off, darting around the yard for five minutes over my protestations. He’s supposed to be limiting his physical activity.
Once he calmed down, I noticed how bad he smelled and, with a public appearance scheduled for tonight, a bath was in order. In the middle of that, fully soaped up, he took off again, running in circles around the yard.
His herniated disc seemed far from his mind. I feared the incident would lead to a relapse, but all day, as in the past two days, it appeared to be bothering him less and less, and the yelps have ceased.
Between the tranquilizers and the the NSAIDs — and despite an unplanned morning swim in a yet to be opened pool — I think he’s making progress.
I haven’t yet told the lady of the manor about the damage he did. Earlier, she offered me the job of pool boy, if I end up staying into the summer, which would certainly look good — unlike the actual pasty and balding, pot-bellied, 57-year-old pool boy would himself — on the resume.
Now I may have no choice, needing to work off my debt for the torn tarp. How’s this for a deal? If you pay me extra, I’ll keep my shirt on.

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.
