'Wachhund' (guard dog / watchdog) consists of 'Wach-' (guarding) and 'Hund' (dog). The component 'Wach-' belongs to the same word family as 'wachen' (to keep watch) and 'bewachen' (to guard), which also helps explain the figurative use.
Ein Wachhund passt auf, während die Bewohner schlafen.
A guard dog keeps watch while the residents sleep.
Common combinations include 'einen Wachhund halten' (to keep a guard dog), 'einen Wachhund einsetzen' (to use a guard dog), and 'einen Wachhund ausbilden' (to train a guard dog). 'Einsetzen' (to use / deploy) describes deliberately using the dog for guarding.
Die Sicherheitsfirma setzt auf dem Lagerplatz einen Wachhund ein.
The security company uses a guard dog at the storage yard.
The figurative meaning often appears in the patterns 'als Wachhund fungieren' (to act as a watchdog) and 'sich als Wachhund verstehen' (to see oneself as a watchdog). 'Als Wachhund' (as a watchdog) describes the monitoring role of a person or organization; in German, 'als' (as) is usually followed by no article in this construction.
Der Verein versteht sich als Wachhund und prüft, ob die Stadt ihre Umweltversprechen einhält.
The association sees itself as a watchdog and checks whether the city keeps its environmental promises.
