A recent scientific study has shed light on why dogs tilt their heads to one side, a behaviour that is widely adored by dog lovers.

Researchers from The Animal Cognition conducted the study and found that only dogs that had learned the names of objects frequently tilted their heads.

Expert Sommese said that ‘dogs tilt their heads in a number of situations’ but ‘only when they hear something that is very relevant to them,’

The study suggests a connection between head-tilting and processing significant, meaningful stimuli.

The researchers hope to delve further into how different contexts and sounds may impact head-tilting behavior in the future.
