What a pretty little girl she is and congrats on the 5000 posts!
I too hope she is ok and and there is nothing more causing her fatigue except the change in weather. She reminds me of my Monty boy.....he looks so depressed or tired all the time too. He has lost a lot of stamina too but think it's due to his sore knee. I know he is in constant pain with it and that's enough to drain anyone.

Keep the pics coming ok.
Hugs
Deb, Monty, & Kiki
