Chewbarkkas medical treatment

Chewbarkka (Chewy) is our 1 year old Terrier/Pug mix that my wife and I adopted at 8 weeks old. He has been the most fun loving and playful dog Ive seen. Unfortunately, Chewy has been very ill lately. Our poor little guy has had to undergo many trips to the vet to try to get this taken care of. In the past two weeks, he's lost sight in his right eye, barely eats and drinks,  and has trembles. The current theory is an autoimmune disease known as GME, that causes the body to attack itself. As I sit here typing this out, he is in an MRI machine getting tested. For the past two weeks he has not been his normal fun loving playing all the time, carpet chewing, car destroying self and it has been the roughest time that Carmen and I have had to endure. Lets not forget about poor crunch who is also very sad and knows something is wrong. Along with that, the bills are piling up and anything anyone is willing to give would be greatly appreciated. We will be forever indebted to you. We will provide constant updates and photos. Please help get our son, and crunch his brother, back.
