Not pinned flat or anything-they're up, but just turned...back. My instructor told me a while ago they'll put their ears sort of down and a little back when they're relaxing or submissive, but what she does seems to me to be a bit beyond that. She also generally has that "hard" look in her eye.
Here's a picture I could find that is sort of what she does...only, she's not dozing when she does it, and the ears are pointed a bit more upwards, but they're facing the same way:
I'm taking it to mean that she's either bored, or irritated, or perhaps both. It seems like disrespect, especially with the look in her eye, but she never actually does anything unsatisfactory and punishing her for this look just confuses her and will make her even more resentful. She will always do whatever I ask, but she usually has her ears turned back about it.
I don't know. What does it mean? How should I deal with it?
EDIT: REALLY sorry the picture is so big. I have no way to reduce the size of it.
