Researchers report that dogs blink more frequently when they see their owners blinking, suggesting blinking may function as a subtle social signal during human–dog interactions. The work is published in the journal *Royal Society Open Science* and is presented as an additional possible meaning for mutual gaze beyond eye contact alone.
Both outlets describe the study’s motivation as building on what is already known about dogs’ responses to human behavior, including “puppy eyes” during direct looking. One interpretation is that blinking can play a communicative role in addition to its biological functions, such as keeping the eyes moist, clearing dust, and giving the brain brief rests while processing visual information.
While the sources agree on the main finding—that dogs blink more often when they observe owners blinking—they differ slightly in emphasis. *Phys.org* focuses on the proposed social-signal explanation and the study’s publication context. *The Guardian* highlights the broader implication that mutual gaze includes more nuanced signals than simple attention, framing the result within wider research on dogs’ ability to read human facial cues.
