bhur asked: What is rocket dogs origins? Did he eat radioactive cat poop? Or maybe he got caught in a tragic rectal rocket accident in a mad scientists secret lab? Or maybe the U.S. military made another hair brained animal related experiment?
Yes, well Rocket Dog was initially designed as a secret weapon by a military group - a failed experiment due to his unpredictable and psychotic nature. Bob later found him in a dumpster.
