Tracy - this post may not be of any help if you have gotten a definitive cancer diagnosis, but I thought I would share anyway. 2 weeks ago I lost my 7 year old Shih Tzu, Miles (in the pic below), to IMHA (basically the same as AIHA). If there is one thing I learned, it's that you have to keep your doggy eating so they can accept the medication. With a fluctuating RBC, I would continue with the Azathioprine in addition to the Prednisone. Those meds are real tough on the stomach though, and the best thing for that is food and some form of stomach acid reduction (Pepsid, Prilosec, etc.). Once they stop taking food, the stomach responds poorly to the meds and it's all downhill from there. Like I said before, if this is speen or another form of cancer, this advice may be of little use.

In my many hours of research on IMHA, I stumbled across this product that has gotten rave reviews. I never had a chance to use it on Miles (it arrived promptly, but sadly after Miles passed), but it doesn't seem like it could hurt. The testimonials are all glowing (no surprise there), and I also spoke to company representatives who sounded geniune and caring. http://www.optimumchoices.com/

Good luck to you and yours.
