Etymology

From Proto-Finnic *koira, from earlier *koj(e)ra, from Proto-Uralic *kojera (“male animal”) (whence also koiras (“male animal”)), derived from Proto-Uralic *koje (“male, man”), in which case the word probably originally meant "male dog" specifically (and possibly displaced peni in the general sense of "dog").
