wiktionary
bull + dog, in reference to bullbaiting.
etymonline
bulldog (n.)
also bull-dog, "small, strong, muscular kind of dog noted for courage and ferocity," c. 1500, from bull (n.1) + dog (n.). So called perhaps from the shape, perhaps because they originally were used for baiting bulls. In U.S. newspaper slang, the bulldog edition (1910) was the earliest run of a daily paper.
