Went to the allergist, max throid is too low. Max has been on ultra hypo allergenic food and he didn't scratch except for the ears and nose, and of course shaking thr ears, which we had been cleansing also frompast experience. He does have an infection so he is on antibiotic, but also higher thyroid meds and he hasn't been shaking his ear or scratching. His thyroid was 1.5 and it should be 3.5 to 4. All the other symptons max has had point to the thyroid. So hopefully we can get this under control and then switch to low fat diet for his pancreas again. Have them do the entended panel blood work and if his thyroid is on the low side insist on it being addressed. I left one vet, then another still wasn't addressing both issues so i finally found an allergist who works wirh alot of shelties and knows there issues. I also did alot of reading and support from this forum. CHECK HIS THROiD! took almost 3 years! Do not give up.
