Oh I'm so sorry..... {{hugs}} and prayers to you and Daisy during this very difficult time.
I sent my/my parents 13 year old GSD mix to the bridge just a week and a half ago. I knew it was going to be hard... but never imagined just how hard it was. But once she was gone and I knew she was well once again I felt a wonderful sense of relief knowing that she was not hurting anymore.
