My fiancee is a vet tech, I have no idea how she deals with this so often. But I can promise you every single person who worked with your dog had it just as hard as you.
We lost ours a few years ago and my girl still gets tears sometimes. She was a breeder in a puppy mill and someone dumped her by the side of the road. Somehow she wandered into our back yard one night and never left.
