σκύλαξ

Uncertain. Compare κύλλα (kúlla, “puppy (hapax)”), σκύλιον (skúlion, “dogfish”), σκύλλα (skúlla, “shark”), as well as Old Armenian ցուլ (cʻul, “bull”), Old Irish cuilén (“puppy”), Lithuanian kalė̃ (“bitch, female dog”), and Russian клей (klej). A Proto-Indo-European *(s)kol- (“animal”) is possible, but problematic. Based on the phonetic issues with connecting the similar words mentioned above, Beekes tentatively takes the word as Pre-Greek;^[1] it is possible that some, all, or none of the cognates mentioned above are taken from the same substrate continuum.
