Why Do Dogs Tilt Their Heads? What the Science Says
Your dog isn’t confused. They might be concentrating. Or they’ve learned the tilt gets snacks.

You say “walk”. Your dog’s head drops sideways like a question mark. The internet melts.
The head tilt is one of the most photographed moves in the dog world, and for a long time almost nobody studied it. That’s changed a little. Here’s what the research actually shows, and which explanations are still just good guesses.
The Short Answer
Nobody knows for sure. There’s decent evidence that head tilts are linked to dogs processing words that mean something to them. There are also a few other theories with less evidence behind them. More than one could be true at once, and different dogs may tilt for different reasons.
The 2021 “Gifted Word Learner” Study
This is the big one. In 2021, researchers at Eötvös Loránd University in Budapest published “An exploratory analysis of head-tilting in dogs” in Animal Cognition. The authors were Andrea Sommese, Ádám Miklósi, Ákos Pogány, Andrea Temesi, Shany Dror and Claudia Fugazza.
They watched 40 dogs: 33 typical family dogs and 7 “gifted word learner” dogs, a rare group that learns the names of toys quickly. All the dogs went through the same three-month training programme to learn the names of two toys. Then the owners asked them to fetch a toy by name (“bring rope!”) while the toys waited in another room.
What they found:
- Gifted dogs tilted in 43% of trials. Typical dogs tilted in 2%. That’s a big gap for dogs who’d heard the same toy names for the same three months.
- Each dog had a favourite side. The direction of the tilt stayed consistent across tests over several months.
- It wasn’t about where the owner stood. The owner’s position didn’t predict which way the dog tilted, so the researchers ruled out “just locating the sound” in this setup.
The authors’ interpretation, in their words: “we suggest a relationship between head-tilting and processing relevant, meaningful stimuli.” They suggest the tilt “could be a sign of increased attention”. They also float the idea that it might be linked to matching the word to a memory of the toy.
Your dog isn’t confused. There’s a chance they’re thinking really hard.
The caveats, because we do those. Seven gifted dogs is a tiny sample. The six gifted dogs who tilted often were all Border Collies. The authors warn against deciding Border Collies are head-tilters, though, because 18 of the non-tilting typical dogs were Border Collies too. They call their study “exploratory” and say bigger studies are needed. Writing about the paper in Psychology Today, ethologist Marc Bekoff also called for research across more breeds.
The 2025 Follow-Up: 103 Dogs and a Right-Side Lean
A 2025 study in the journal Animals, by a team including researchers at George Washington University, went bigger. It filmed 103 dogs from seven breed groups plus mixed breeds. Owners gave them four levels of communication, from no cues at all up to “rich affective cues coupled with dog-directed speech” (yes, the baby voice).
What they found:
- The more communicative the owner, the more the dogs tilted. The chattiest, most expressive condition got the most head tilts.
- Dogs leaned right more often than left.
- Neutered males tilted more often than spayed females.
The authors say the right-tilt bias is consistent with the left-brain language processing seen in humans. That’s a hypothesis about brain lateralisation, not a finding that dogs process language like people do. They also flag that some of their subgroups were small.
The Other Theories (Clearly Labelled as Theories)
Theory: they’re seeing around their muzzle. Psychologist Stanley Coren suggested a dog’s snout blocks part of their view of your face, especially your mouth. Tilting might give them a clearer look. His 2013 online survey of 582 people found that 71% of owners of longer-muzzled dogs said their dog tilted frequently, compared with 52% of owners of flat-faced dogs. Coren himself called it “a first step”. It’s owner-reported survey data, not a controlled experiment.
Theory: they’re pinpointing a sound. The American Kennel Club’s explainer quotes behaviourist Jill Goldman, who thinks locating sound matters mainly when a dog isn’t facing you. When they are, she says, “it’s about frequencies and inflections. The dog may be listening for the high-pitched baby talk.” Remember that the 2021 study found the owner’s position didn’t predict tilt direction.
Theory: it gets rewarded. Goldman also suggests the tilt is “reinforced”, because it’s often followed by something great, like “Do you want a cookie?” Behaviour that gets rewarded tends to happen more. So if you squeal and hand over a treat every time your dog tilts, congratulations: you may be training it.
Theory: it’s about being cute for us. The 2025 paper notes earlier studies where people rated puppies and adult dogs as “cuter” with a tilted head. That shows humans like the tilt. It doesn’t show dogs do it on purpose to charm us.
| Explanation | Evidence so far |
|---|---|
| Processing meaningful words, paying close attention | Two peer-reviewed studies (2021, 2025) |
| Consistent favourite side, like handedness | 2021 study (small sample) |
| Seeing around the muzzle | One owner survey (2013) |
| Locating sound | Expert opinion; the 2021 study didn’t support it for that setup |
| Learned because it gets rewarded | Expert opinion, consistent with basic learning |
What Does This Mean for You?
Mostly: enjoy it. The tilt looks like a sign your dog is tuned in to you. Researchers are still arguing about exactly what’s going on inside that tilted head.
If you want more tilts, the reward theory gives you a free trick. Talk to your dog in a happy voice, and when you get a tilt, mark it and reward it. Nobody gets hurt, and you both get a good time. That’s the whole philosophy around here, and it scales up: see A Recall That Works Without a Remote.
Don’t use the tilt to test your dog. A dog who doesn’t tilt isn’t less clever. Most typical dogs in the 2021 study barely tilted at all.
When a Tilt Isn’t Cute
The tilts in these studies were brief, in response to people talking. A head that stays tilted is a different thing. The AKC article quotes Goldman: “If you see a persistent head tilt, and it seems not to be related to anything, go straight to your veterinarian.”
Our standard line applies: if this is new or comes with other changes, get your vet to rule out pain first. Sudden, lasting tilt? That’s a vet visit, not a photo op.

Your dumb questions
Is my dog tilting because they understand every word I say?
Probably not every word. In the 2021 study, dogs who had learned the names of toys tilted far more often when they heard those names. That suggests the tilt is linked to processing meaningful words, not a full vocabulary.
My dog always tilts to the left. Is that a thing?
It might be. The 2021 study found each dog’s tilt direction stayed consistent over months, a bit like being left- or right-handed. A 2025 study found a population lean to the right.
My dog never tilts. Is something wrong?
No. Most typical dogs in the 2021 study barely tilted at all. A non-tilter is a normal dog.
My dog’s head has been tilted all day, even when I’m not talking. Cute?
Not this time. A persistent tilt that isn’t tied to anything is a vet issue. Book an appointment.
