In the iconic painting “His Master’s Voice (opens in new tab),” a terrier cocks his head as he listens to his owner’s voice coming from a gramophone. This gesture is 1 lots of dog owners will be familiar with, but why do dogs tilt their heads?

In a 2021 study in the journal Animal Cognition (opens in new tab), researchers in Hungary carried out the 1st scientific investigation of head-tilting in pooches. They discovered that dogs could incline their heads as they are remembering particulars they uncover meaningful.

“Head tilts in dogs are a pretty identified behavior, but the most surprising factor for me was that no 1 prior to us investigated it,” study lead author Andrea Sommese (opens in new tab), an ethologist (a scientist who research organic animal behavior) at Eötvös Loránd University in Budapest, told Reside Science. 

In an earlier 2021 study in the journal Scientific Reports (opens in new tab), Sommese and his colleagues analyzed videos from about the globe in which dog owners asked their pets to fetch them a toy by saying its name. Though 33 pooches have been not in a position to find out the names of any new toys right after 3 months of practice, seven gifted dogs have been in a position to find out additional than ten names for the duration of that time, with 1 female border collie, Whisky, properly identifying 54 toys.

Even though conducting the study that appeared in Scientific Reports, the researchers noticed that all 40 of the dogs cocked their heads for the duration of the tests. The scientists subsequent investigated when the canines performed these tilts.

In the following Animal Cognition study, the scientists discovered that the gifted dogs tilted their heads 43% of the time when asked to retrieve a toy by name. The other pooches tilted their heads in only two% of these circumstances.

“We are not claiming that only gifted dogs tilt their heads even though common dogs under no circumstances do it,” Sommese stated. “Common dogs also do that, some additional generally than other people, but in this certain predicament, when the owner asks for a toy by its name, only the gifted dogs show a good tilt.”

These findings recommend that dog head-tilts are associated to sounds the pets have discovered to uncover essential. 

“Dogs tilt their heads in a quantity of circumstances, but it appears that they do this only when they hear one thing that is really relevant to them,” Sommese stated. “It appears that this behavior is strongly connected with sound perception, and it could be one thing they do when they are attempting to listen additional closely, or perhaps when they are a bit confused, just like humans do.”

In addition, the researchers discovered the side of the tilt was constant in the gifted dogs across 24 months of tests, but the favored side differed from canine to canine. This suggests 1 side of the brain of every dog could favor the mental activity underlying head-tilting, the scientists noted. Just as humans normally favor working with 1 hand more than the other, lots of dog behaviors favor 1 side, such as the paw with which dogs attain for an item (opens in new tab), the path in which they favor wagging their tail (opens in new tab) and even the nostril they use additional for the duration of sniffing (opens in new tab), they explained. 

Future investigation can discover what other sounds or contexts could trigger canine head-tilting, stated Monique Udell (opens in new tab), a human-animal interaction researcher at Oregon State University, who did not take component in the research.

“Research like this 1 are essential due to the fact they remind us that we, as humans, also have a lot to find out about what a dog’s physique language is communicating to us,” Udell told Reside Science.
