How to stay young? How to grow old? Dogs show us the way to both


Dogs have a knack for helping us accomplish our goals. Somehow, they seem to know what those goals are without ever being told. Maybe, they know our goals better than we do.

With no apparent effort, they can help us accomplish our missions … whatever the mission … even missions that are completely opposite from one another.

Dogs, for instance, can help us stick to a routine, or get us out of a rut. (Ace has done both for me.)

They can enlarge our circles of friends, and — at those times solitude might be best — keep it from getting too lonely. (Ace has done both of those, too.)

And they can both keep us young and show us how to grow old.

That last trick, I think, is particularly impressive.

Dogs, when you think about it, show us how to live our lives (in the moment, with abandon), cope with our maladies (with brave perseverance) and die our deaths (with grace and dignity).

Between the examples they offer, the similarities between our species and the uncovered secrets dogs may still hold, it’s no surprise that science and medicine and more than a few other fields of study are increasingly turning to them for answers.

What dogs have to teach us about living a healthy life — some of it obvious (if we pay attention), some of it suspected and undergoing research — was the subject of an article last month in AARP Magazine.

As it noted, dogs, as they continue to evolve alongside us, are increasingly mirroring us, right down to getting the same diseases and disorders.

“… This evolution is ongoing, a process scientists call convergence: Human and canine genes, shaped by the environment we share, are evolving in lockstep. Today, along with home security and leftover disposal, dogs confer a host of wellness benefits, especially to kids and older people,” the article’s author, David Dudley, wrote. “People with dogs sleep better, weigh less and get more exercise than dog-free peers.”

“And there are the less tangible perks, the ones cataloged in Marley & Me–style books. This burgeoning “dogoir” literary genre revolves around the reductive but basically correct idea that a dog is foremost an instrument of personal growth: It exists to ease your existential anxieties, impart lessons about love and friendship, and teach you how to be a better person.”

But as noted by Dudley, who weaves the lessons his dog Foghat taught him into the article, that’s just the beginning of what dogs might have to share.

He cites a couple of research projects as examples of the possible answers dogs may hold when it comes to aging.

Neuroscientist Elizabeth Head is studying elderly beagles at the University of Kentucky in an attempt to determine why, by age 6 or 7, they start showing signs of the microscopic beta-amyloid plaques that are the hallmarks of Alzheimer’s disease.

About a third of the beagles will succumb to canine cognitive dysfunction syndrome, about the same percentage of Americans over 85 who will get Alzheimer’s.

“It could be that living in our environment — our food, our water, our homes — has made dogs more vulnerable,” she says.

Head thinks dogs might hold the key to defeating it. Past studies, she notes, have demonstrated that an antioxidant-rich diet and “behavioral enrichment” — a course of memory drills and new-skills training — can significantly delay or diminish plaque development and memory impairments.

At the University of Washington, Daniel Promislow, an aging researcher (in both meanings of the phrase), has assembled a team to join in a Canine Longevity Consortium. Through a a grant from the National Institute on Aging, they’re working on the first national longitudinal study on aging in dogs, which will include looking at how dogs stay so seemingly happy and carefree as they advance in years.

On the downside, as we all know, they can relatively suddenly become frail, forgetful and sick — as was the case with Dudley’s dog, Foghat.

“…He entered his dotage in roaring good health. Around his 18th birthday, I Googled “oldest dog in the world,” because I started to wonder if he was closing in on a record. He was what gerontologists would call a successful ager.

“And then, seemingly overnight, he wasn’t. If you have to go — and you do — a swift slide into decrepitude is the preferred way. The phrase is “compression of morbidity,” when the infirmities of age are delayed until the bitter end. Still, it’s no picnic. The joints went first. He started limping after a vigorous bouncing-a-soccer-ball-off-his-nose session. Then he needed help climbing into the car or crawling under the bed, his favorite sleeping spot.”

As Foghat declined, Dudley wrote, his “senescence appeared as both a comfort and a warning of what awaits: Some fears and eccentricities will lift with the years; others will only deepen. One by one, the things you love to do become too difficult and slip out of your life.”

With his death, Dudley says, “I was struck by the strange new stillness — the foreign silence of a household without a dog. It was as if a machine that had been humming in the background for a long time had suddenly been switched off.”

Amid that silence, Dudley, like many other grieving dog owners, started quantifying what he learned from Foghat.

” …And now that I’m no longer young, and he’s dead, I’ll do my best to follow the path Foghat blazed into my life’s last half…” he wrote.

“So eat the best food you can afford. Go for a walk, even if it’s raining. Take a lot of naps. Keep your teeth clean and your breath fresh, so that the people you lick will not flinch. And when someone you love walks in through the door, even if it happens five times a day, go totally insane with joy.”

A dog that can read? You be the judge

Willow’s owner claims her dog can read — only three phrases, but still.

What do you think? Is the dog actually reading the words? Or is something else at play?

Dogs understand as well as 2-year-olds

Dogs possess a 2-year-old child’s capacity to understand human  gestures, including pointing, head-turning and gazing, according to two recent studies.

Pet owners often use baby talk, scientifically known as “motherese,” with both children and dogs, allowing canines and kids to receive similar social stimulation, according to a report on

The studies suggest dogs may understand humans better than even chimpanzees, our closest living animal relatives do.

In one study, Gabriella Lakatos, a researcher in the Department of Ethology at Eotvos University, used a combination of finger-, elbow-, leg- and knee-pointing gestures to help dogs locate hidden food. Then they put children through a similar drill – allowing them to search for their favorite toy.

Two-year-olds children  and dogs understood everything except knee-pointing, according to a paper published in the current issue of Animal Cognition.

Lakatos said that “in human children between the age of two and three years, important changes take place that go beyond the capacities of dogs.” Many of these changes have to do with development of language skills.
