Oh wow, Im sorry I cant offer any advice on this subject. But I am amazed that a Vet would do you two that way!! Im so sorry to hear about her passing, but atleast she isnt suffering.
BTW, I was recommended a Vet who does blood testing and supposively is the best in the US. I plan on having my dogs blood shipped to her for a general blood check up here soon.

I would give her a call and ask her opinion on your situation....
