Blinking keeps eyes moist, sweeps away bits of dirt and dust, and helps the brain rest when processing visual information. But in dogs, it may also serve another function as a subtle social signal. That was one of the conclusions of new research published in the journal Royal Society Open Science, which found that dogs blink more often when they see their owners blinking.
