Shep is a simple dog who hates Halloween. Admittedly that mask was stupid and that damn kid needed to be taught a lesson. A Shep lesson. Did anyone else wonder where the Halloween parade actually was? I just saw a few kids skipping around in terrible costumes for what? To win a few balloons? At the end I though Shep was going full Cujo and was about to kill everybody in sight. Which... probably would have saved the movie. This was some sort of school educational film which is odd considering the lack of any kind of lesson. Well, other than don't mess with Shep. Shep will just ruin you.
