Vine Street. Cultural references In the 1926 picture book Strongheart; The Story of a Wonder Dog, Trimble wrote the story of how Strongheart came to the United States and was chosen for motion pictures, of his training, and of his progress in films culminating with White Fang. Strongheart's popularity inspired Doyle Packing Company to adopt his name and photograph for a canned dog food in 1932. Strongheart Dog Food did a respectable business, especially in the Midwest, and was available in stores until at least 2002. J. Allen Boone wrote two books, Letters to Strongheart (1939) and Kinship with All Life (1954), about animal communication and the survival of the dog's soul after death. Both books were reprinted many times and remain classics of the Spiritualist faith. Boone was a Washington Post correspondent who looked after Strongheart for an extended period while Murfin and Trimble were away on business. Boone and Strongheart reportedly formed a deep bond, and Boone believed the dog was a transformational being. 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." Strongheart: Wonder Dog of the Silver Screen (2018) is a novel for ages 8–12 by Candace Fleming and illustrated by Caldecott Medal winner Eric Rohmann. Kirkus Reviews said, "Like a silent movie plot, Fleming’s narrative is full of adventure, romance, and suspense." The book received a starred review in Booklist.
