Alexandra Day (born 1941) is an American children's book author. Alexandra Day is a pseudonym; her real name is Sandra Louise Woodward Darling. She is the author of Good Dog, Carl, which tells the story of a Rottweiler named Carl who looks after a baby named Madeleine. The book was first published in 1985 by Day's own publishing company, Green Tiger Press. Good Dog, Carl has been followed by a whole series of popular Carl books, published by Farrar, Straus and Giroux. Early life Day was born in 1941 in Cincinnati, Ohio to a large and close-knit family. Painting was a popular family recreation, and almost every family excursion included one or more easels and a variety of sketch pads, chalks, paints, and pencils. For four years, the family lived on a hundred-acre farm in Kentucky. Here young Sandra grew especially fond of riding and training horses, and became a dog owner for the first time. Living in the country also provided plenty of time for reading, a life-long passion. Career She and her husband, Harold Darling, founded a publishing company, Green Tiger Press, in 1970. Meanwhile, Day began a career in illustration, and illustrated her first book in 1983: The Teddy Bears' Picnic, based on a popular children's song by Jimmy Kennedy. In 1986 the Green Tiger was sold to Simon & Schuster and the Darlings started a book packaging company called Blue Lantern Publishing. In 1993, the Darlings moved to Seattle and founded a new publishing company, Laughing Elephant. Harold died in 2016 and Laughing Elephant is now run by Day and her children, Benjamin and Sacheverell. Carl book series According to Day, the inspiration for Good Dog, Carl came from a trip to Zurich, Switzerland in 1983. Day and her husband saw in a bookshop window there a was looking an antique German picture sheet by the great German illustrator and pop-up artist, Lothar Meggndorfer, of a poodle playing with a baby who was supposed to be taking a nap. This image proved the inspiration for Good Dog, Carl. Day's own dog, a Rottweiler named Toby, was the model for the book's main character, and since then five other family Rottweilers have been models for the books. All of the dogs have had their own names: Arambarri, Zabala, Zubiaga, Zulaica and Abelard. Day's granddaughter, Madeleine was the inspiration and model for the baby in the original Carl
