What a story. I have always been with my dear ones when they were euthanized. They were two exceptions, both whippets, who died in the hospital of cancer that grew quickly inside the pericardium, a sad affliction of sight hounds.. I have the ashes of all nine of my dogs.
If this little dog was suffering in those five months, this is horrifying. I have mixed emotions since I don't know. The family was reunited one last time and the little one has been euthanized.
