Leave it to scientists to confirm what we already know, and to do so using words we don’t begin to understand.
Case in point: Nervous dogs often have nervous owners. This is not to say a nervous dog can’t have a cool as a cucumber (coolus cucumberus) owner. Nor is it to say some highly twitchy (humanus nervosa) folks can’t have calm dogs.
Only that, as anyone who visits a dog park knows, nervous owners tend to have nervous dog at the end of the leash.
The new study buttresses the concept that our dogs tend to take on our personalities, and that tension — while it may not actually “flow down the leash” — is picked up on by our dogs, and often reflected in their own behavior.
It looks at the chemistry behind that.
The study at the University of Vienna — published in the journal PLOS One “investigated dyadic psychobiological factors influencing intra-individual cortisol variability in response to different challenging situations by testing 132 owners and their dogs in a laboratory setting.”
You might understand that, or, you (like me) might not know spit — or that cortisol levels can be measured through it.
In the study, the researchers measured the levels of cortisol — and the variability of those levels — in the saliva of dogs and owners put through stressful situations.
In addition, they assessed the personality of both dog and human participants — ranging from highly sensitive and neurotic to secure and self confident.
“We calculated the individual coefficient of variance of cortisol (iCV = sd/mean*100) over the different test situations as a parameter representing individual variability of cortisol concentration,” the study’s authors wrote. “We hypothesized that high cortisol variability indicates efficient and adaptive coping and a balanced individual and dyadic social performance.”
For a more reader-friendly account of the study, check out Stanley Coren’s Psychology Today blog:
“You can think of people who are high in neuroticism as being sensitive and nervous while people who score low in neuroticism are secure and confident. In this study, the dog owners who scored high in neuroticism had dogs with low variability in their cortisol. This suggests that dogs with highly neurotic owners are less able to deal with pressure and stress.”
“Conversely, dog owners who were more laid back and agreeable had calmer dogs. Those folks have greater variability in their cortisol response, suggesting that they are better able to cope with situations involving tension and strain.”
The study says the male dogs of female owners often have less variability in their cortisol responses and are often generally less sociable and less relaxed than male dogs belonging to male owners.
(That’s the study saying that females generally score higher on measures of anxiety and neuroticism — not me. I would be way too nervous to say that.)
“Owners behave differently because they are pessimistic or neurotic, and perhaps dogs read the emotions of their owners and think the world is more dangerous — so they are more reactive to it,” the study says. “It looks like people who are pessimistic have dogs which are worse at coping with stress than others.”
Of course, where a dog was before ending up with its owner can play a pretty big role, too.
I, for example, am the cool as a cucumber owner of a nervous dog. He came from a farm in Korea where he was being raised to become meat. That would tend to instill some nervousness in anyone.
Three months after being adopted by me, he still gets pretty nervous — around large groups, when hearing loud noises. I don’t know about his cortisol levels, but at these times he whimpers, sheds profusely — is there such a thing as projectile shedding? — and pees in inappropriate places, such as on my leg.
He is making great strides in every way, but Jinjja still needs to chill, and get less worked up by new situations.
Of all the factors that shape our dogs — genetics, environment, owners — time (and its cousin, patience) may be the most important ones of all.
So my game plan is to provide him with plenty of both, expose him to new settings and situations, and show him that not all the world is a dangerous place — all while being a mellow role model.
In other words, impossible as it might be, I’m going to have to become EVEN cooler.

Does the hot dog need a makeover?
The nation’s largest pediatricians group thinks so. The American Academy of Pediatrics — un-American as it may sound — is calling for sweeping changes in the way the hot dog is designed to minimize children’s chances for choking.
In a policy statement issued earlier this week, the group identified the hot dog as the greatest food-related choking hazard to children, particularly those ages 3 and younger, and said the shape plays a large role in making it unsafe.
The academy proposes warning labels be placed on hot dogs, and that consideration be given to manufacturing them — gasp! — in the shape of a patty.
The academy cited statistics showing 17 percent of food-related choking deaths among children come from from hot dogs. Other common food choking hazards include grapes, apples, popcorn and nuts, the group said. Of the 141 choking deaths in kids 14 and under in 2006, 61 were food-related, according to an Associated Press story.
The doctors say high-risk foods — including hot dogs, raw carrots, grapes and apples – should be served to small children in pea-sized pieces to reduce chances of choking.
We’d agree with that much, but we think it’s up to parents, as opposed to the government, to see that their childrens’ food is cut into manageable pieces.
