«كَلْبْ حَي خِيرْ مِنْ سَبْعِ مَيِّتْ»

The saying ranks usefulness above former greatness. A humble creature that is still alive can still serve some purpose, while even a lion or other great beast of prey is worth nothing once it has died. Present capacity to help outweighs past power or reputation.

More broadly, it favors what actually works now over what is impressive in name only. Something lowly but active and available is preferable to something noble or formidable that has lost all ability to act or to benefit anyone.

Use it when weighing a humble but useful person, resource, or option against a powerful or prestigious one that can no longer offer any benefit. The comparison may sound insulting if directed at a person, since the useful creature in the proverb is a dog.
