If your Vet is open to consulting with Dr. Couto, that would be the way to go. If not, it certainly wouldn't hurt to get all the labs and surgical/visit notes and send them to OSU yourself. They are wonderful with which to work! Since it's not an emergency situation, you do have time to do some research on your own so that you can become familiar with various treatment options and experiences of others (Circle of Grey on yahoo). If there are no other constraints, a consult with an oncologist, who would be open to consult with OSU, would be helpful. Once you're comfortable that you know enough to make the best decision for Blueberry, you can take the next step.
I will keep you and Blueberry tucked gently in my heart and will be sending healing white light and prayers of comfort.
