The above linked article talks about a website you can visit to read books that are rewritten so that the dog doesn’t die in the end, like the originals. It covers books like Cujo, Old Yeller, and Where the Red Fern Grows.
I am not too sure about these books, since, at least in Old Yeller and Cujo, the dog’s death is a major part of the book. One of these days I’ll check out the rewrites, though. Maybe.
