You are a lovely Lady indeed, and you look wonderful for being a senior pooch. I have a soft spot for Shelties, since my son had beautiful Tiffany (who looked like your twin) as part of his family. Sadly, she did not have the long life that you have had.
Here's hoping that you have many more Christmases to spend with your wonderful family. Congrats on the honor of being DOTD today.
MERRY CHRISTMAS TO YOU AND YOURS
