It sounds like you are on the "other side" of your grief. Unfortunately, I've been through the process too many times. I didn't experience it for the first time until I was in my 30's. It doesn't get easier per se, but you learn how to deal with (read: squelch) the pain, if that makes any sense. Those pictures are so touching - I can tell you were and are such a good dog mom. If you get a new dog... best of luck and good for you for saving a life.
