Doggy Lit: A History of Dogs in Books
Brainpickings showcases a book called Dogs In Books: A Celebration of Dog Illustration Through the Ages. You can see dog-related illustrations from Arthur Rackham, Edward Lear and other folks.
It’s easy to come up with lists of famous dogs from books – Toto, the hound of the Baskervilles, Lassie, Buck from Call of the Wild, Bulls-eye from Oliver Twist, Cujo, Nana from Peter Pan, Fluffy from Harry Potter and the Philosopher’s Stone, Lad from Albert Payson Terhune’s books, Spot from Dick and Jane, and Clifford the Big Red Dog. I could go on and on.
(NB – I didn’t add Walter the Farting Dog to the list.)
