German Shepherd
From Tardis Wiki, the free Doctor Who reference
The German Shepherd was a breed of dog. Sammy Star owned two German Shepherds, Brandy and Lady, who he used to guard his magic trip props and Weeping Angel. (PROSE: Magic of the Angels)
Professor Frederick Marius had a German Shepherd called Kelso. He couldn't take Kelso to his new workplace in space, so he created K9 and left Kelso with Grace. (PROSE: One Man and His Dog)
