Sorry to hear about your loss, Mary K. When I had my little Maltese put down, the administrator that did the deed, stroked her little 5 lb body and said, "Now Liza's going to be with her Mommy, again". What a nice thought.
Nevertheless, it still brings tears to your eyes, but it is heartbreaking to see them go though the pain of suffering. Now, why is it that our pets must die before we do? I guess, so we can rescue another poor animal that needs a loving home, to sooth our sorrow. Good luck.
