What a sad statement that letter made. I know what I would do, and I truly believe that my vet would have handled this situation differently. I can certainly understand your anger, Genia.
All I can say is a cheer for the kids and their mom at least trying. And I'm sad for the poor dog that lost its life in the process.
I think Carrie's idea of a phone number and message that vet bills will be paid is a great one.
