the.com/dog watch
The shortest watches at sea, invented so sailors don't eat dinner at the same dull hour forever.
means A short two-hour watch aboard ship (the first dog watch from 4 to 6 p.m., the second from 6 to 8 p.m.), splitting the evening so the crew's rotation shifts each day instead of locking sailors into the same hours.
from From English nautical usage, where the standard watches run four hours each but the evening was cut into two short ones. The name is often explained as a corruption of 'dodge watch'—a watch that 'dodges' the usual length—though this is folk etymology and unproven. More plausibly it nods to the dog: a 'dogged' or curtailed thing, or perhaps the brief, light sleep of a 'dog-sleep.' The honest truth is that the exact reason for the dog is uncertain, lost somewhere in the salt and rope of old sea-talk.
