A Dog-Gone Puzzle

Dogs have always been a part of our household.  They are companions, friends, comforters and protectors.  Fictional families seem to feel the same way.  Below are 26 dogs from books, TV and movies (2 pictures contain 2 dogs). Take a trip down memory lane and see how many you can name.

I'll hide the comments for a bit so you can't peek at others' answers.  Answers will be posted Saturday.
