So very sorry for your loss, ML. I lost my"baby" right after my D all those years ago, and that was even more difficult than watching xh fade away at that same time. I did call him and he came to the vet, but left just as quickly. However, in the end, he did pay the bill at least. It is sad how robotic and inhuman they become.
Just know that your beloved doggie is in a better place waiting for you and that things will come together, with brighter days ahead. It's moments like these that strengthen us and moves us further forward, as painful as it is at the time.
