Latin Canis is surely linked to PIE *kwon, but
there's an anomaly; the "correct" form must have been
Nom. *co: Gen. *cunis; or by analogy *co:, *co:nis;
or even *co:n-es
But Canis, Canes must have an influence of root
*ken- "young" cf. Greek kainos, Sansk. kani:na- Lat re-cen-t-,
like
Welsh cenau "puppy" and Slavic s^tene
