Apollo & Zeus - Doberman pinscher guard dogs seen on the detective drama MAGNUM, P.I./CBS/1980-88. Apollo & Zeus lived at the mansion of novelist Robin Masters on the Island of Oahu. The dogs patrolled the perimeters of the estate and answered to the commands given by a stuffy British manservant Jonathan Quayle Higgins III (John Hillerman) who affectionately called the dogs "The Lads." Frequently the dogs went chasing after Thomas Magnum, a private investigator and live-in security guard for the estate. Apollo and Zeus' real names were Brutus and Dominique. They were trained by Scott Hart and earned $1,000 a week. When the producers tried to get look-alikes to save money (The dogs had to be flown in from Los Angeles), the series star Tom Selleck said "No!" He felt comfortable with those particular dogs chasing him and didn't want replacements.
