Books and movies with accurate rep?

I work in a library and recently had a request from a patron for some literature, movies, documentaries, etc. featuring service dogs.

Off the top of my head I could only name one (Rescue and Jessica, children's book), and it's the only piece of media we have about SDs at our very small library. So I need a bit of help.

I'll take anything! Childrens books, nonfiction, fiction, documentaries, movies, TV shows, whatever you've got! I'd love to have a handout for people who are curious about my service dog so I can direct them to different resources.
