Most of the American stories where they took park were drawn by Tony Strobl, who revamped the original look of this duo, developed by Hubbard. They had a more human-like look and Strobl made them look like Carl Barks' dognoses (human faces with dog snouts). Besides, one of them became quite shorter than the original character. Strobl used the Doe Boys in various comic stories for the market outside of the USA during the 1970's whose events invariably also involved Donald Duck, his cousin Fethry and Uncle Scrooge McDuck.
