Man, you just broke my heart! My Sheltie was with me through thick and thin for 14 years, and I had to put her to sleep. Hardest day of my life!! My sincerest condolences. We will see them in the next life.
All night at work I was agonizing over the thought of putting Josephine to sleep. That beautiful little dog even saved me of that.
I know that was hard for you.
