In dogs, the larger upper eyelid, which contains the cilia or eyelashes, is more mobile than the lower eyelid. When the eyelids are closed, most of the ambient light is prevented from entering the eyes. Restrained dogs blink 10–20 times/min in comparison to unrestrained dogs. Some 50% of dogs' blinks are incomplete. Puppies normally open their eyelids between 10 and 15 days of age.
