The Adventures of Rex the Wonder Dog #1

History

Robert Kanigher and Alex Toth had already demonstrated the commercial appeal of a heroic dog co-feature when their Streak the Wonder Dog grew popular enough to displace Green Lantern from the covers of his own title in the late 1940s; with the superhero genre in decline and Streak's book cancelled, they channeled that energy into a dedicated vehicle for a new canine protagonist. Rex was conceived from the outset as a white German Shepherd war veteran of the K-9 Corps rather than a super-powered sidekick, lending his early adventures a post-war, genre-blending flavor that mixed crime procedural, nature adventure, and military reminiscence. Toth handled the pencils for the opening three issues alongside inker Sy Barry, with co-writer Dave Wood assisting Kanigher on the debut issue's scripts; from issue #4, Gil Kane took over the art duties and, with Bernard Sachs inking, defined the series' visual identity for the remainder of its run. The series' name was shortened on its cover from 'Rex the Wonder Dog' (used on issues #1 and #2) to the full 'Adventures of Rex the Wonder Dog' from issue #3 onward.

Trivia · 8 facts

• First appearance and origin of Rex the Wonder Dog — a white German Shepherd and decorated Army K-9 Corps veteran — written by Robert Kanigher (with co-scripter Dave Wood) and drawn by Alex Toth, with inks by Sy Barry; cover also by Toth and Barry.
• Cover date: January/February 1952, published by National Periodical Publications (DC Comics); the series ran bimonthly for 46 issues, concluding with the September/October 1959 issue.
• The issue contains four features: the origin story 'Trail of the Flower of Evil!' (in which Rex clears his owner's brother of a murder charge), plus 'The Killer Bear!', 'Rex — Forest Ranger!', and a nature text piece, 'The Rockies — Nature's Stronghold.'
• Rex is explicitly established as a war veteran ('overseas,' decorated for bravery) in issue #1; later continuity — most notably Secret Origins #48 (April 1990), written by Gerard Jones — retroactively gave him a Captain America-style super-soldier serum origin, a retcon that has remained in canon.
• The creative team of Kanigher and Toth had previously co-created Streak the Wonder Dog, who debuted in Green Lantern #30 (1948) and eventually eclipsed Green Lantern on the title's own covers — Rex was effectively their second-generation rethinking of that character for the new market era.
• Alex Toth illustrated only the first three issues; from issue #4, Gil Kane took over the pencils, with Bernard Sachs as primary inker, and Kane also became the principal cover artist for the series.
• The series served as the launch pad for Detective Chimp (Bobo), who first appeared as a back-up feature in Adventures of Rex the Wonder Dog #4 (August 1952), written by John Broome — a character still active in DC continuity decades later.
• After the series was cancelled in 1959, Rex went unmentioned for 18 years until Steve Englehart brought him back in Justice League of America #144 (July 1977); subsequent appearances include DC Comics Presents #35 (1981), The Flash vol. 2 #46–47 (1991), and a recurring role in Shadowpact (2006–2008).
