Indiana
From Wookieepedia, the Star Wars wiki.
Indiana was an Alaskan malamute dog owned by George Lucas in the 1970s. Indiana was the inspiration for the character of Chewbacca,[1] and later became the source of Indiana Jones' name.
In the movie Indiana Jones and the Last Crusade, Henry "Indiana" Jones Jr. admits to having taken for himself the name of the family dog, Indiana, of whom he had very fond memories.
