Coast Guard Mascot of WWII

from Life Magazine

SINBAD spent 11 years in the Coast Guard
aboard the USCGC Campbell
because a grouchy landlord's rule against pets. 

 A crewmember bought the mixed-breed dog as a gift for his girlfriend,
but when she could not accept him, the sailor snuck him aboard ship.

SINBAD went on to earn many service ribbons during World War II,
which he wore on his collar.
