Taken from Magnum Mania...
According to Larry Manetti's book Aloha Magnum, Zeus and Apollo were played by several different Doberman Pinchers throughout the show's run. In the first half of Season One, three local Doberman Pinchers were used, two female dogs named "Cola" and "Nohea", and one male named "Joe". When their trainer, Karl Lewis Miller, left the show mid-season, professional Hollywood animal trainer Scott E. Hart was brought in as the official animal supervisor for the show. At the beginning of Season Two, the producers had Scott Hart bring his own dogs from the mainland, and they were two males and one female. The two males were "Whiskey" and "Brutus" and the female was "Dominique". At the beginning of Season Four, Scott was told that the dogs were being written out of the script in order to save costs. However, the "Lads" were saved by Tom Selleck and John Hillerman who didn't want the show to go on without them!
