The dog which appeared in this episode was owned by infrequent guest-star Sandra Burns, daughter of George Burns and Gracie Allen. Sandra was pregnant at the time, so her parents concocted a scheme to slip her some extra cash by casting the dog and paying Sandra $300 to serve as its handler.
In one of the few stunts seen on the show, Harry Morton (or, a stunt man in the guise of actor Larry Keating) takes a running dive out the window of the Morton dining room, a huge dog in hot pursuit.
