I have a friend whose dog has gme and at first they thought it was a disc issue so ER sent her home with metacam and a few months later her back legs were paralyzed and turned out to be GME. She has a maltese and on the group they said the breeds most likely to get this are yorkies and maltese and it creeps up about 2 years of age. Her dog had had vaccinations two months prior and then all the symptoms started occuring but first was pain in spine and they misdiagnosed as a disc issue at ER.
She is doing fine now but under the care of a neurologist.
This disease can be managed but the sooner the treatment the better. They try to do heavy doses of steroids at first so i am sure your vet is using steroids and that is why you are showing a little improvement as it takes the swelling down.
If it is a severe case of GME then they need to do chemo drugs and steroids as it is an autoimmune disease where the body is attacking itself. My concern is it is pretty serious as it affected all 4 limbs not just 2 like my friends dog
