She is now curled up on her mat with one of Kylie's rope toys (quite a magpie this girl!) and is in a much better mood. Tomorrow we are back to work and hopefully she will be feeling a bit more cooperative. She isn't ornery because she is mean spirited. She is ornery because she is extremely smart (what I like to call "problem solving intelligent") and doesn't always see the point of obedience.
I have found, in my experience, that smart dogs also tend to be moodier. They are a bit more aware of their surroundings and so their surroundings affect them more.
I am sure she will feel better tomorrow, and if she doesn't we may have a good play session instead of a third workout. WOOPS! She is trying to pull the tag off of her mat. Duty calls!
