Please speak with Ladyjane from Yorkie Haven Rescue, our sweet Roriee has GME, although they thought she has AAI to begin with. She is a wonderful person and extremely knowledgeable about the disease. I am sure she can help you and support you down this road.
I listed a few links for you regarding GME which I am sure you have researched by now. But seeing how well Roriee is doing I hope it can give you some comfort.
