Jim has been on Pergolide since the summer; we also had him tested for IR, but this was done after I had made dietary changes since I suspected strongly that he would be. Our vet is not strongly versed in the disorder, so I've been kind of winging it and found the website I mentioned and also joined their group at Yahoo. Don't know what I would have done without them :) It's true that there are seasonal rises in ACTH~ in a perfect world with unlimited cash (certainly not
my world!) I would have tested him again...things are going pretty well right now, so I'm going to carry on with his current dosage and will re-test before spring to see if it needs to be adjusted.
April is when he foundered last year, even though he had no access to grass and hay was being soaked. I am hoping, REALLY hoping with the change in diet and meds we won't have another episode....that was the second time in a year that he foundered
