Why do dogs tilt their heads?

Scientists aren’t sure, but a small 2021 study found dogs that know many toy names tilt their heads far more often when they hear one, a hint the tilt goes with concentrating on words.

Quick Answer

Nobody knows for certain, but research is starting to offer clues. In a small 2021 study in the journal Animal Cognition, researchers in Hungary watched 40 dogs as their owners asked them to fetch a familiar toy by name. A small group of “gifted word learner” dogs, which know the names of many toys, tilted their heads 43% of the time, compared with just 2% for typical dogs. The researchers suggest the tilt may go with processing meaningful words, perhaps a sign of concentration. Each dog also tended to tilt toward its own favorite side. Other ideas include hearing a sound better or seeing past the muzzle: in an informal survey of 582 dog owners by psychologist Stanley Coren, 71% of owners of longer-muzzled dogs said their dogs tilted often, compared with 52% of owners of flat-faced dogs. A head tilt that doesn’t go away is different: it can signal an ear or balance problem, and it’s worth a trip to the vet.

Key Facts

Short answer: Scientists aren’t sure, but it may go with concentrating on meaningful words
Key study: 2021, Animal Cognition: word-savvy dogs tilted 43% of the time, typical dogs 2%
Favorite side: Individual dogs tended to tilt the same way every time
Other ideas: Hearing better, or seeing past the muzzle

Listening to words that matter

In the 2021 study, only the dogs that had learned many toy names tilted their heads often when their owners named a toy. The researchers think the tilt may accompany processing meaningful, relevant sounds, perhaps as the dog matches the word to its memory of the toy.

Other explanations

Some researchers think tilting helps a dog pinpoint a sound. Others suggest it helps a dog see around its own muzzle to read a person’s face. Psychologist Stanley Coren’s informal survey found owners of longer-muzzled dogs were more likely to report frequent tilting, but that idea hasn’t been tested in controlled studies.

When a tilt isn’t cute

A brief tilt when you talk is normal. A head that stays tilted can be a sign of an ear infection or a problem with the balance system, and a vet should take a look.

Myth vs. Fact

MythA head tilt means your dog understands every word.

FactOnly dogs that knew many toy names tilted often in the study, and scientists still don’t know exactly what the tilt means.

MythAll dogs tilt their heads when you talk.

FactTypical dogs in the 2021 study tilted only 2% of the time.

The Bottom Line

Scientists don’t fully know why dogs tilt their heads, but the best evidence links it to paying close attention to words that matter to them. A tilt that never goes away is different, and worth a vet visit.
