Throw a dog who has never gone swimming into a pool and, pretty much instantly, he’ll start moving his four legs in a series of motions we’ve come to call the dog paddle.
Throw a human who has never gone swimming into a pool and — though the possibilities are much higher for helpless flailing about, cussing, drowning, or becoming traumatized for life — he may eventually come to his senses enough to try and work his way back to the side of the pool. He’ll do so not using a butterfly stroke, breast stroke or Australian crawl, but by doing what dogs do.
The dog paddle: It’s seemingly instinctual. It’s primitive. And though we humans mostly outgrow it, it remains sort of the default mode of propelling ourselves through water.
Just how primitive it may be is under investigation by Dr. Frank Fish, a professor of biology at West Chester University who — maybe because of his name, maybe not — has spent most of his career studying how marine mammals swim.
Most recently, he has been studying the swimming motions of dogs, and he has concluded that they are very similar to the motions dogs use in trotting. That explains the ease with which most dogs can make the transition from land to water — requiring no lessons, and (generally) little coaxing: They basically propel themselves the same way in water as they do on land.
That their stride and strokes are nearly identical is interesting in itself, but Fish thinks it could also help explain how whales and dolphins ended up in the ocean.
Fish subscribes to the theory that marine mammals were intitially four-legged land dwellers who ventured into the water one day (likely dog paddling at first), decided they liked it better there, then evolved into such super swimmers that they no longer needed legs, or, for that matter, land.
He borrowed a swimming pool used to rehabilitate horses at the University of Pennsylvania.
Analyzing the video, Fish and fellow researchers saw that dogs swim much like they run — with diagonal pairs of legs churning in unison, according to Science Daily. Fish presented his findings at the 2014 Society for Integrative and Comparative Biology (SICB) meeting in Austin.
While there’s plenty of dog research we’d categorize as a silly waste of time, we find all this pretty intriguing.
First, it reminds us that practice makes perfect — to think that long, long ago there might have been a couple of four-legged dolphins who didn’t know how to swim, hesitating at the edge of the water: “I dunno, it looks dangerous … should we go in?”
Second, in an era when we’re increasingly relying on computers to do our thinking for us, it serves as a warning that those muscles we don’t use can disappear. It raises a host of interesting questions about our future, and our past.
Why is it we humans tend to dog paddle in our first encounters with water? Is that some sort of instinctual nod to a past when we got about on four legs, instead of two?
If cavemen had spent more time at the swimming hole, might we homo sapiens have evolved into something more amphibious?
Given that, might mermaids really exist?
It’s kind of inspiring to think there might have been a day when dolphins, the planet’s most graceful swimmers, were total klutzes in the water — that they started off splashing about with some awkward looking dog paddling and progressed to the point where they could actually leap out of the water.
It reminds us that, maybe, anything is possible with enough hard work — even when it comes to behaviors we might think are genetic and therefore unchangeable. Do we sometimes wear our genes too tightly, and allow them to restrict us from leaping into new things, and getting over old ones?
We wish Fish luck in unraveling how four-legged terrestrial forms evolved into no-legged, finned ones. And as long as the dogs involved in his research are having a good time – given Fish is letting his own dog be used in the study, we assume they are – we have no problem with them helping the professor prove his point.
In other words: Go Fish!

Remember Denver, the guilty, oh-so-guilty, looking yellow lab that was captured on video by her owner while she was being interrogated in the case of the missing cat treats?
We suggested — partly in jest — that she might be innocent, that appearances can be deceiving, not to mention misinterpreted, and that, just maybe, the cat did it.
Now — with the video having gone viral, with dog and owner having appeared on the ABC’s Good Morning America, with a line of “guilty dog” merchandise having been spawned — there’s more reason to believe that Denver might have been wrongly convicted. How guilty one looks and how guilty one is are two different things — especially when it comes to dogs.
Guilt, research shows, may be just another human emotion that dog owners anthropomorphically ascribe to dogs.
And all those behaviors Denver exhibited – avoiding eye contact, lying down, rolling into a submissive position, dropping the tail, holding down the ears or head, raising a paw – are more likely triggered by the owner’s semi-scolding tones than any feelings of “remorse.”
This reminder/revelation comes from someone who knows, who did her master’s dissertation on this very topic, and who produces one of my new favorite blogs, Dog Spies.
Julie Hecht is a New York-based behavioral researcher who has worked with Patricia McConnell and Alexandra Horowitz. She wrote her dissertation at the University of Edinburg on “Anthropomorphism and ‘guilty’ behavior in the dog,” and did her research with the Family Dog Project in Budapest, Hungary. She recently started Dog Spies, which focuses on the science behind dog behaviors and the dog-human relationship, and she divides her time between research, lecturing, blogging and working with individual pet owners.
As was my goal (plug alert) in my recently published book, “DOG, INC: The Uncanny Inside Story of Cloning Man’s Best Friend,” she attempts to take the boring out of science, thereby making it interesting and understandable. “Scientific journals should be titled, ‘Lots of great information within, a tad boring to read!’ Dog Spies translates that information and shares it with you,” reads the introduction to her blog.
Judging from her “guilty dog” blog entry — and you know its trustworthy, because it has footnotes – Denver’s appearance, with her owners, on the ABC morning show raised her hackles a bit.
“According to the dictionary, ‘news’ is ‘information about recent events or happenings.’ I did not see any news during that morning show. Instead, I saw a bunch of morning personalities throwing out assumptions and offering the audience pleasing banter and humorous judgments about dogs. They provide no real information or ‘news’ about what happened to the cat treats.”
Here Hecht has hit on one of my pet peeves — pun definitely not intended. Rather than shedding some light, doing some research, and furthering our understanding of canines, the ABC segment — like so much of what the media, blogs included, feed us about dogs — was the kind of cutesy, substance-free fluff that reinforces misinformation and misunderstanding.
Like most everyone else, the smiling morning show hosts concluded Denver must have eaten the cat treats. When shown the empty bag and asked, “Did you do this?” Denver displays squinting eyes, averts her head and makes a highly laughable presentation of her teeth.
Guilty. Guilty. Guilty.
Or maybe not.
Hecht cites a 2008 research paper that says 74 percent of dog owners attribute guilt to dogs, and believe dogs know when they have done something owners disapprove of. But scientific research shows that it’s not knowledge of a misdeed, or remorse, that leads to the guilty look, but an owner’s scolding. (See the New York Times piece, “It’s an Owner’s Scolding That Makes a ‘Guilty’ Dog.”)
Or, see this — a video Hecht made that shows a dog named Gidget being falsely accused:
As Alexandra Horowitz, author of “Inside of a Dog,” once put it: “We’ve trained them that when they see us angry, they give us that guilty look. I’m not saying they don’t feel guilt … I can’t test that yet. But we generate the context that prompts them to produce this look.
Why then, in the guilty dog video gone viral, does Denver show these behaviors when the other, presumed innocent family dog, Masey, does not?
“Research finds that even post-transgression, not all dogs show the ‘guilty look’ in the presence of a non-scolding owner,” Hecht says. And, transgressions aside, it might be the simple fact that Denver is a more expressively submissive dog, according to Hecht, who says part two of her entry on the “guilty dog look” will be appearing soon on her blog.
Why do dogs show what appears to be a guilty look more so than do their progenitors, wolves?
“Dogs have, for the most part, incredibly malleable and expressive faces (much more so than, say, cats) and from this, we can often see the subtleties of their eyebrows going down or up or their wide forward-facing eyes, becoming wider. All of these things could impact how humans attribute mental states to dogs,” Hecht told me.
My theory is there’s more at play — though maybe I’m giving dogs more intellectual credit than they deserve. I think mastering the guilty look is another way dogs have evolved since their domestication, and to cope with their domestication — part of their ongoing adaption to pethood. By showing submission, some of them may have have figured out, they can keep the peace, and maybe even get a belly rub or a Milkbone.
To me, the even more interesting question, when it comes to “the guilty look,” is whether, even before the scolding comes, dogs can sense it’s about to. Before a word comes out of the owner’s mouth, before an angry stance is even taken, can dogs sense that some displeasure is churning within us?
I, without any research or footnotes to back me, believe so. My scientific explanation for this: It’s magic.
Dogs are figuring us out. Which, until recent years, is maybe more than they could say about us. We’ve always been more concerned with their brawn than their brain, more concerned with their beauty than their behavior. It’s man’s hand that has led to the vast diversity of shapes and sizes in dogs. And while breeders have begun to put a higher priority on temperament, it can still be argued that appearance is placed above all else.
Could it be, in their way – without the aid of microscopes, opposable thumbs or access to our pedigrees – dogs are looking more deeply into us than we are into them? Could it be, during their time in domestication, dogs, as a species, have amassed a wealth of knowledge on how to best get along with humans, and have become even better at doing so than humans?
I think there’s more at work than breeding and genetics and instinct when it comes to dog behavior. An ongoing and not fully understood evolution is at play in the dog-human relationship. And that is the reason – all those unanswered questions about behavior, coupled with those we wrongly assume we know the answers to – why dog blogs of substance, like Hecht’s, are important.
At the same time, though, I rue the day when our understanding of dog behavior is complete — when we can explain every act of dog as stemming from some lingering instinct, or adaptation to their domestication. For then the magic will be gone.
I want all three — my science, my magic and my dog. Does that make me greedy?
