I need closure over the loss of my dog?

Trust me, your dog loves you. She may havenot even known herself where she was going, but she knows that if you knew where she was going you would hive her one last hug. She knows that and she loves you and understands you couldn't because you didn't know what was happening. Trust me, I know how it feels to lose your best friend. I had a Rottweiler that I had when I was 2 and had to put her down when I was 12, last summer. Now I'm 13 and understand you so much and how hard it is for you. Good luck.
