If you stop and think about who was in the 'Lassie' movies, it's difficult to think who was in them, apart from Elizabeth Taylor. You remember the dog, not the people! So if you're going to be in a movie, and it's called 'Gremlins', it's going to be about Gremlins, and what people are going to remember are the Gremlins.
Most of what happens in the world is far beyond a dog's comprehension, so they must turn to their faith in us to help them navigate life's treacheries. Don't we, also, have unanswerable questions about the vagaries of modern existence for which the answer is beyond human grasp, so that only our faith can guide us?
