I love the emotion you're showing us in this piece! My dog had a really rough time with fireworks this year so I totally relate...and she won't go out if there's a little thunder in the background.
I think you can make a few changes - many of which have already been mentioned - that will enhance your story.
If you change the camera angle so we can see where the dog crate ends it won't create a tangent.
If you add the wire to more accurately describe the dog crate.
If you open the window slightly the wind can help break up the static shapes of the curtains - remember - DRAMA!
If you add a few house hold items to describe the room the dog is in.
