Dachshund Ninety-two out of 138. That is where dachshunds landed when psychologist Stanley Coren ranked breeds by obedience and working intelligence, parked in the middle of the pack while border collies and poodles hogged the podium.
Then you actually live with one.
You watch a twelve-pound sausage dog calculate the exact angle needed to shove a couch cushion sideways, build herself a tunnel, and disappear into it before you finish saying her name. That is not a mid-tier brain. That is an engineer with short legs.
So which is it? Is your dachshund a middling student, or is he running circles around a preschooler?
The honest answer is stranger than either option, and by the end of this you will have five tests you can run on your own living room floor to find out where your dog actually lands.
What "Dog IQ" Actually Measures
Here is the first thing nobody tells you: there is no single dog IQ. Researchers slice canine intelligence into separate categories, and a dog can be brilliant in one and hopeless in another.
Instinctive intelligence covers what the breed was built to do. Adaptive intelligence covers problem solving, learning from mistakes, and figuring things out without help. Working and obedience intelligence covers how fast a dog learns commands from a human.
Guess which one gets measured most often?
The Obedience Ranking Problem
Those famous breed rankings mostly test one narrow skill: how quickly a dog obeys a new command, and how often it obeys on the first try.
That is a fantastic measure of biddability. It is a pretty lousy measure of thinking.
A dog that hears "sit" and immediately sits is cooperative. A dog that hears "sit," glances at the treat bag, notices you are holding chicken instead of the boring biscuits, and then sits with dramatic slowness to see if you will upgrade the offer is doing something considerably more complicated.
Dachshunds do the second thing constantly.
Obedience measures how much a dog wants to please you. Intelligence measures how much a dog can figure out without you. Those are not the same test, and confusing them has slandered an entire breed for decades.
Where the Five-Year-Old Comparison Comes From
The comparison in the title is not made up, though it needs some unpacking.
Research on canine cognition suggests the average dog can learn around 165 words and signals, roughly matching a human two-year-old. Exceptionally bright dogs push past 250.
Numbers get more interesting elsewhere. Dogs appear to handle basic arithmetic at the level of a three or four-year-old child, they can count small quantities, and they notice when one treat goes missing from a group of five.
Social intelligence is where things get genuinely wild. Dogs read human gestures, follow pointing, track our gaze, and detect unfair treatment. On some of those social tasks, they outperform chimpanzees and land closer to a four or five-year-old kid.
So your dachshund is not going to file your taxes. But she might be better than a kindergartener at reading the exact moment your resolve about the bed rule starts to crumble.
The Dachshund Difference: Stubborn or Brilliant?
Every dachshund owner has been told their dog is stubborn. Usually by someone with a golden retriever.
The label is lazy. Dachshunds were bred to go underground alone, corner a badger in a dark tunnel, and make life or death decisions with no human anywhere nearby to consult.
A dog bred for that job cannot be built to wait for instructions.
Built for Independent Decisions
Selective breeding gave dachshunds a brain wired for autonomy, persistence, and a very high tolerance for ignoring outside opinions. Those traits look like disobedience in a training class and look like genius when the dog opens a latch you were sure was dog-proof.
Persistence is the underrated part. Studies on problem solving often find that the dogs who succeed are not necessarily the smartest; they are the ones who keep trying after the first four attempts fail.
Dachshunds keep trying. Ask anyone who has watched one work on a puzzle feeder for forty minutes with the focus of a safecracker.
A retriever asks you what to do next. A dachshund decides what to do next, then informs you afterward, usually from somewhere she is not supposed to be.
Five Tests You Can Run This Afternoon
None of these require equipment you do not already own. Run them when your dog is alert and a little hungry, not right after dinner, and keep the whole session under fifteen minutes.
Score each test using the points listed, then add them up at the end.
Test One: The Towel Test
Let your dachshund see you drape a bath towel over her head, covering her eyes completely. Start the clock.
Under 15 seconds to get free: 3 points. Fifteen to thirty seconds: 2 points. Longer than thirty seconds, or she just sits there wearing it like a ghost costume: 1 point.
Some dogs freeze because they are unbothered rather than confused, so run this one twice before you judge her.
Test Two: The Cup Game
Line up three cups upside down on the floor. With your dog watching, put a treat under one cup, then block her view for five seconds.
Release her. Going straight to the correct cup earns 3 points. Checking one wrong cup first earns 2 points. Wandering off to sniff the baseboards earns 1 point and a note about her priorities.
Test Three: The Barrier Problem
Set up a low barrier: a baby gate, a laundry basket on its side, a cardboard box wall with a gap at one end. Put a treat on the far side where she can see and smell it but cannot reach directly.
Solving it in under a minute is 3 points. One to three minutes is 2 points. Giving up and barking at you to fix it is 1 point, though it is arguably an excellent use of her staff.
Test Four: The Vocabulary Check
Count the words your dog reliably responds to without gestures or context clues. Names, commands, objects, and yes, the offensive ones like "vet" and "bath" all count.
Twenty or more distinct words scores 3 points. Ten to nineteen scores 2 points. Fewer than ten scores 1 point, and probably says more about your training time than her brain.
Test Five: The New Trick Test
Pick something she has never done before. Teach it in a single five-minute session, then test her the following day.
Remembering the new trick with one reminder earns 3 points. Needing a few repetitions earns 2 points. Blank stare earns 1 point.
Reading Your Dachshund’s Score
Add up all five tests for a total between 5 and 15.
13 to 15 points: you own an unusually sharp dog and should probably start locking cabinets. This dog needs a job or she will invent one.
9 to 12 points: solidly bright, fully capable of learning far more than she currently gets asked to. Most dachshunds land here.
5 to 8 points: either your dog is a laid-back thinker who saw no reason to hurry, or she was distracted. Retest in a week before drawing conclusions.
One important caveat: a low score often measures motivation, not ability. Dachshunds are famous for deciding a task is beneath them.
The dog who solves your puzzle in nine seconds and the dog who stares at it for nine minutes may have identical brains. One of them simply cared more about the snack.
Making a Smart Dog Smarter
Scores are fun, but they are a snapshot, not a ceiling. Cognitive ability responds to use, and a bored dachshund gets destructive long before she gets dumb.
Rotate her puzzle toys weekly so novelty stays part of the routine. Scatter feeding in the yard turns dinner into twenty minutes of scent work, which is exactly the kind of mental exercise her nose was designed for.
Teach nose games indoors on hot afternoons. Hide treats under three cups, then five, then behind furniture, and let her track them down.
Add new vocabulary deliberately. Name her toys, use those names consistently, and ask her to fetch specific ones; plenty of dogs build surprising object vocabularies once someone bothers to teach them.
Short sessions beat long ones. Five focused minutes twice a day will outpace one exhausting half hour, and your dachshund will stay eager instead of checking out halfway through.
