Joan, you wrote that has been going on for 17mo., don't you think that is time enough to see improvement or cure? I do, and would move on (I think you are beginning to realize this by the questions you have).
As for vet schools, don't be afraid of going there. Just equate them to teaching hospitals, these resident vets train under a professor who actually is in control of your pets care. The resident suggests the care but the professor rounds with them just as in a human hospital. They have the most up to date research, equipment and labs and have seen almost everything in their medical practice. so don't worry about your little one being a guinea pig.
