Border Collie At some point you started spelling things out loud. W-A-L-K. Or you switched to a code word, or a different language, or you stopped saying the word at all and just thought about the leash very quietly. You did that because the dog kept winning.
That’s a real result, and most people wave it off as the dog reading their tone or their body. Some of it is. But not all of it, and the part that isn’t gets interesting fast.
The usual move here is to compare a dog to a five year old, note that the kid knows something like 5,000 words, and call it a rout. Fair enough on paper. But that comparison is doing a lot of quiet work, and once you pull it apart, the gap starts looking less like a canyon and more like a ditch you could hop across on a good day.
Which brings us to the fun part: your dog. Not a research dog with a full time trainer and a decade of daily sessions. The one currently staring at you because you shifted your weight in a way that might possibly indicate a walk.
You can test that dog this afternoon. All of it takes about twenty minutes, costs nothing, and requires a towel, some treats, and your willingness to be judged by a dog.
What "IQ" Actually Means When the Subject Has a Tail
Here is the honest framing before we start handing out scores.
Dogs do not take IQ tests the way children do, because the tests were built for a species that can hold a pencil and cares about grades. What researchers measure instead is a scattered bundle of skills: how fast an animal learns a new command, how well it solves a physical puzzle, whether it can follow a human’s intent.
Psychologist Stanley Coren’s work on canine cognition put Border Collies at the very top of the working intelligence rankings, and the yardstick he used was blunt but useful. A dog near the top of that list typically learns a new command in under five repetitions and obeys a known one on the first try roughly ninety five percent of the time.
That is not a five year old. That is closer to a two year old with a very specific set of talents.
The part where your dog quietly wins
Then there is social cognition, and this is where the comparison gets genuinely weird.
Show a chimpanzee a pointed finger and it mostly ignores you. Show a Border Collie a pointed finger, a glance, a chin tilt, or a half second pause before you say a word, and it has already made a prediction about what happens next.
A dog that reads your intentions before you finish forming them is not performing a trick. It is running a model of your mind, and updating it constantly.
Human toddlers develop that skill around their first birthday. Your dog arrived with it preinstalled and has been refining it against you personally for years.
The part where the five year old wins easily
Kids ask why. That is the whole game.
A five year old can reason about things that have never happened, imagine a scenario, tell you a lie with a plan behind it, and understand that you know something they do not. Border Collies do none of that in any meaningful way.
So the fair answer is that the two minds are not ranked, they are shaped differently. Your dog is a specialist. The kid is a generalist with a much longer runway.
Now go get a towel.
The Twenty Minute Home IQ Test
Run these in one session if your dog stays engaged, or split them across a couple of days. Keep it light. A stressed dog scores like a dim one, and that tells you nothing.
Have treats ready, and start each test only when your dog is calm and paying attention to you.
Test 1: The Towel Problem
Let your dog see and smell a treat, then place it on the floor and drape a bath towel over it. Start your timer.
Under 15 seconds: 5 points. 15 to 30 seconds: 4 points. 30 to 60 seconds: 3 points. Over a minute, or gives up: 2 points.
The clever part to watch for is not speed, it is method. A dog that lifts the edge of the towel with its nose is solving the problem. A dog that pounces on the lump and paws frantically is just being enthusiastic about the general concept of treats.
Test 2: The Cup Shuffle
Set out three cups upside down in a row. With your dog watching, put a treat under the middle one. Wait ten seconds, then release your dog.
Five points if it goes straight to the correct cup with no sniffing detour. Three points if it checks a wrong cup first, then corrects. One point if it works down the line at random.
Then run it again, but this time slide the cups around slowly before releasing. That version separates the dogs tracking an object from the dogs tracking a memory of where they last saw it.
Test 3: The Brand New Word
This one is the closest thing to Chaser’s test that you can run at home.
Take a toy your dog knows well and one it has never seen. Put them a few feet apart. Ask for the new toy by a name you have never used before, something like "get the wumbo."
Your dog has no idea what a wumbo is. But it does know what the other toy is called, and the reasoning available to it is the word I do not know must belong to the object I do not know.
Five points if it brings the new toy on the first or second try. Three points if it gets there after a few attempts. One point if it just brings its favorite thing, which, to be fair, is a defensible life philosophy.
Toddlers use this exact inference to build their vocabularies. It is called fast mapping, and a handful of Border Collies have demonstrated it under controlled conditions.
Test 4: The Detour
You will need a baby gate, a fence panel, or an open doorway with a barrier beside it.
Stand on the far side of a barrier your dog cannot pass through, hold up something it wants, and call it. The solution requires briefly moving away from the goal to go around.
Five points for an immediate route around. Three points for a few seconds of hesitation first. One point if it stands there pressed against the barrier, staring at you with total confidence that you will eventually fix this.
Test 5: The Cold Read
No treats for this one. Sit in a chair, stay quiet, and glance deliberately at your dog’s leash. Then look back at your dog. Do nothing else.
Five points if it reacts to that glance alone. Three points if it needs you to look twice. One point if nothing registers.
Most Border Collies score high here, and many owners find this test unsettling, which is usually the correct response.
Adding It Up
21 to 25 points. You are living with a dog that is genuinely, measurably clever, and you almost certainly already knew it because it has been outmaneuvering you for years.
15 to 20 points. Comfortably bright, well within the breed’s normal range, and probably underemployed.
10 to 14 points. Either the tests were run on a hot afternoon after a long walk, or your dog’s talents lie somewhere these five puzzles do not reach.
Why a low score is not a verdict
Motivation contaminates everything here.
A dog that has decided the towel is boring will score the same as a dog that cannot solve the towel, and those are entirely different animals. Retest on a different day, with better treats, when your dog is fresh.
Age matters too. Puppies under six months are still assembling the hardware, and senior dogs are often solving the problem correctly but slowly, which the scoring above punishes unfairly.
The Uncomfortable Follow Up Question
Say your dog scored 23.
You now have documented proof that you share a home with an intelligence that learns words, solves physical puzzles, reads your posture, and has nothing to do for eleven hours a day.
An unstimulated Border Collie does not get bored. It gets a project, and it does not consult you about what the project will be.
That project is usually your baseboards, the mail carrier, or a shadow on the wall that it has decided requires ongoing management.
So treat the score as a workload estimate rather than a bragging right. Puzzle feeders instead of bowls. A new trick every couple of weeks. Nose work in the yard. Fifteen minutes of real thinking will drain that dog more thoroughly than an hour of fetch, and it costs you far less energy.
Your five year old, meanwhile, still cannot find a treat under a towel in eleven seconds. Small victories.
