Hmm... this is a tough one. I agree with some fine points qbchottu has made about "if there is no history, then there may be less concern and reason for the surgery." However, I would want to research the hypothesis that GDV is a genetic disposition. I haven't researched it in a while, but I'm fairly confident that I've read that it isn't known whether the disease is genetically influenced. And as such, the family history may be irrelevant.
On the other hand, I would completely agree with her that if there WAS a genetic history of GDV, I'd be very much more likely to tack.
