It is one of my favorites of all time. I am a firm believer, at the cost of respect from some "christians", that animals are in heaven. I could be wrong, but if I am I always think of that episode of Twilight Zone.
Love that episode. The one where the man and his hound die in a swamp.......then find themselves at the gate to heaven......God says dogs aren't allowed.....so the man doesn't enter and keeps going and comes upon a second gate..
