Trash Dog I

Outer perimeter sensors detected a behemoth intruding the magical Foggy Bottoms Resort and Spa.  Headquarters assigned an identifier of Trash Dog I.  At 4:26 AM Code Red shelter in place was set in motion.  In the morning the kindly old pensioner picked up the half-dozen cat food cans this monster had licked clean, then scattered.  the Face of Everyman was asked to determine the legality of his dog tags.
