COMMENT: The comparison seems plausible both semantically ('wolf':'dog') and phonetically; not quite clear, though, are the laryngeal features of the first consonant (we may deal with an assimilation in PEC, and then we will have to reconstruct *kwăǯē; or it may be a dissimilation in PWC: *gwăǯē > *kwăǯē > PWC *kʷǝč́:ǝ).
