I am glad you posted this as it is SCARY to me that this is polling out this way
I joined the gme group and reading about this more after rorie incident and seems alot of dogs are getting this after vaccinations
It is not a direct cause but since gme can be disease or autoimmune related they are tying the two together. On the group today they stated that when the annual vaccine cards go out this time of year they have alot people join the group regarding gme shortly after
they also stated they are seeing it mostly in yorkies and maltese breed
Dr Sisson is the expert on GME so they are forwarding his paper for me to read as well and he said the protocol that he recommends is one year booster then only rabies every 3 years there after and he believes the dog has immunity for 10 years after that one year booster for dhpp also he said no real reason to titer as even a low titered dog can have immunity
