Oh, Lori, such a sad outcome from "just a rabies vaccination." And, I think you bring up a good point: the recessive genes for this disease, whether they are there in all cases or not, could easily be triggered by a vaccination.
Then, we're back to understanding more about epigenetics: the things that turn genes off or on are, many times, decisions we make.
I wish you the best in your very difficult situation. Before pred for the allergies, I'd sure encourage you to hire a vet homeopath. That's curable, while the DM seems not to be. See my Resources page for the AVH list and get your female some help.
