Where's Jack?

Cassidy loves her dog, Jack. Anything and everything is referred to as "Jack". Lately I have been shutting the door to her room when we play in there so she stays put, but Jack is not allowed in the room. So, Cassidy has started looking for him under the door (notice Jack's nose peeking through), and, of course, on the other side of the door, Jack is doing the same thing. We have always thought of our dogs as our children, but now I really believe it seeing that Jack and Cassidy have the same mannerisms (butts in the air).
