To find a book about a Great Dane that scared coyotes, I recommend:
* Searching online book retailers: Use keywords like "Great Dane coyote story," "dog scares coyotes book," or "Great Dane children's book."
* Checking your local library's catalog: Many libraries have online catalogs where you can search for specific titles or keywords.
* Asking a librarian for help: Librarians are experts at finding books and can often point you in the right direction.
Good luck finding the perfect book!
