A term for methusalem-aged toothless and blind but still aggressive German Shepards and German Dachshounds. It is always expressed in 3rd person (he instead of you) with a warm friendly voice of rapture patting the dogs head with emphasis when their Feini successfully shat, brought a stick, tore a blanket or bit someone.
The opposite of a Feini is a "Pfuihund" (filthy dog).
Such a Feini he is. Yes, he is such a Feini.
Something delicious to eat or bite into.
The bait of a Feiner
Das ist ein Feini. (That's a fine thing.)
