I'm very sorry to hear about Jesse. My dog jade looks like a mini version of him! We are in the process of finding out if she has this disease. Did x-rays and extensive blood testing to rule out other possibilities, everything came back perfectly normal. Now we have to do a AChR antibody test (I think that's what's it's called), this test will tell us if she has myasthenia gravis or not. 3000 dollars is a lot of money. I have only spent about 300 so far, but she is not as sick as him, she is still eating and drinking ok but wobbles around like a little old lady I just hope we caught this early enough! Jesse is in my thoughts and prayers!
