In the video game, Grand Theft Auto III, Marty Chonks owned the Bitch 'n' Dog Food Factory in the Portland borough of Liberty City. His wife had an extramarital affair with Carl Johnson before she was killed by her own husband, Marty Chonks. In the end, CJ killed Marty and took over his dog food empire. It is assumed that Carl Johnson will either start his game or assign players with some mission in Grand Theft Auto IV from this hideout. Since no dogs can be seen in GTA3, it is assumed that they are housebound like mentally challenged people who can't cross the street by themselves.
