From Middle English hog, from Old English hogg, hocg ("hog"), possibly from Old Norse hǫggva ("to strike, chop, cut"), from Proto-Germanic hawwaną ("to hew, forge"), from Proto-Indo-European kewh₂- ("to beat, hew, forge"). Cognate with Old High German houwan, Old Saxon hauwan, Old English hēawan (English hew). Hog originally meant a castrated male pig, hence a sense of "the cut one". (Compare hogget for a castrated male sheep.) More at hew.
