What does watchdog mean?
A watchdog is, in its literal sense, a dog kept or trained to watch over a place or person. The word now also denotes a person, organization, committee, official, or electronic system that monitors another institution or process in order to detect wrongdoing, inefficiency, abuse, or excessive activity. This extended sense developed from the watchdog's traditional role as a guard. In public and institutional contexts, a watchdog often represents opposition, oversight, or scrutiny, although the term can be neutral when describing a formally assigned monitoring role. As a verb, “to watchdog” means to observe or scrutinize something closely, usually with the implication that problems or improprieties may be present. The word is used in both British and American English. Familiar examples include watchdog committees, watchdog groups, and watchdog timers in computers and other technical systems.

Where does watchdog come from?
“Watchdog” was formed in English by combining “watch” with “dog,” originally referring to a dog kept to watch over a place. Its later figurative sense developed from that literal function, applying to people or organizations entrusted with monitoring other people or institutions. Modern technical meanings, such as a watchdog timer, continue the original idea of continuous vigilance, though in those contexts the device rather than a dog performs the watching.
