OMG Kathy! I so feel for you.... how worried you are over your Winston. It's that helpless feeling that is the worst.... that it is beyond your control what is going on with his precious little body. If your vet cannot come to a definitive diagnosis, perhaps he could forward Winston's test results to one of the better know Veterinary Schools? They always have the most state of the art laboratories and diagnostic facilities. I know that years ago, when my Dad's Yorkie became very ill, his vet did this, a diagnosis was made and his little baby lived for another 11 years!
I am sending prayers for Winston and big hugs to you for the day,
Lauren
