"Strongheart: The World’s First Movie Star Dog" (2014) is a picture book for young audiences by Caldecott Medal winner Emily Arnold McCully. "The New York Times" praised her "meticulous job of recreating the quicksilver world of that bygone media age. The megaphones, bobbed hair and jodhpurs are all here. And in Etzel, a dog born and bred to be strong and brave, she has given young readers a rare portrait of a Hollywood hero who was just as heroic off-screen as on."
