In the iconic painting “His Master’s Voice (opens in new tab),” a terrier tilts his head as he listens to his owner’s voice coming from a record player. This gesture will be familiar to quite a few dog owners, but why do dogs tilt their heads?
In a 2021 study in the journal Animal Cognition (opens in a new tab), researchers in Hungary performed the initially scientific study of head tilt in dogs. They discovered that dogs can tilt their heads whilst remembering information they locate considerable.
“Head tilts in dogs are a relatively properly-identified behavior, but the most surprising point to me was that no 1 had investigated it prior to us,” study lead author Andrea Sommese (opens in a new tab), an ethologist (scientist who research all-natural animal behavior) at Eotvos Lorand University in Budapest, he told Reside Science.
In an earlier 2021 study in the journal Scientific Reports (opens in a new tab), Sommese and his colleagues analyzed videos from about the planet in which dog owners asked their pets to fetch them a toy by saying its name. Though 33 dogs have been unable to study the names of any new toys right after 3 months of education, seven gifted dogs have been in a position to study a lot more than ten names for the duration of that time, with 1 female border collie, Whiskey, appropriately identifying 54 toys.
Although conducting a study that appeared in Scientific Reports, researchers noticed that all 40 dogs tilted their heads for the duration of the tests. The scientists then investigated when the canines performed these tilts.

In a comply with-up Animal Cognition study, scientists discovered that gifted dogs tilted their heads 43% of the time when asked to retrieve a toy by name. Other puppies tilted their heads in only two% of these instances.
“We’re not saying that only gifted dogs tilt their heads whilst common dogs never ever do,” Sommese mentioned. “Common dogs do that also, some a lot more typically than other folks, but in this precise scenario, when the owner is searching for a toy by name, only gifted dogs show a good slant.”
These findings recommend that dog head tilts are connected with sounds that pets have discovered to look at vital.
“Dogs tilt their heads in a quantity of conditions, but they only appear to do so when they hear one thing that is quite vital to them,” mentioned Sommese. “This behavior appears to be strongly associated to sound perception, and it could be one thing they do when they are attempting to listen a lot more meticulously, or possibly when they are a bit confused, just like humans do.”
In addition, the researchers discovered that the side of the tilt was constant in the gifted dogs more than the 24 months of testing, but the favored side differed from dog to dog. This suggests that 1 side of each and every dog’s brain might favor the mental activity underlying head tilt, the scientists noted. Just as humans have a tendency to choose utilizing 1 hand more than the other, quite a few dog behaviors favor 1 side, such as the paw with which dogs attain for an object (opens in new tab), the path in which they like to wag their tail (opens in new tab), and even the nostril they use a lot more when sniffing (opens in a new tab), they explained.
Future study might investigate what other sounds or contexts might lead to dogs to tilt their heads, mentioned Monique Udell (opens in new tab), a human-animal interaction researcher at Oregon State University who was not involved in the research.
“Research like this are vital mainly because they remind us that we, as humans, also have a lot to study about what a dog’s physique language is telling us,” Udell told Reside Science.
