I tried looking it up on the web, but it appears Ginny's Patronus is never shown in the books. I really thought the silver doe that appeared in the forest was Ginny's. That is was Snape's Patronus just surprised the heck out of me.

In the OotP movie, Ginny's patronus was a stallion. Since neither hers nor Ron's were mentioned in the books and JKR revealed in an interview that Ron's was a Jack Russell terrier, that detail for the movie came straight from JKR.

I thought it a little humorous that Luna's patronus was a hare, a well known crazy character from "Alice in Wonderland."

In the OotP movie, Ginny’s patronus is shown as a horse. They also show Luna’s patronus, a hare, which is mentioned in DH, and Hermione’s patronus, an otter.
