guilty?

I don't know who looks the most guilty!!

Let me introduce Millie, our boxer-cross. We adopted her from the RSPCA on Saturday and have been settling her in, and finding out all about her.
1. she doesn't play with balls.
2. she does like sticks.
3. she scowls at cats, and wants to run at birds.
4. Tea is at 6pm, and she lets us know.
5. She sits and lifts a paw, for a treat.
6. She has no idea what 'stay' means.
