My boy has been diagnosed very recently with a rare form of cancer, Canine Thyroid Carcinoma, which accounts for only about 1% of all tumors in dogs. He's being treated by an oncologist and internist and the prognosis is actually very good. With surgery to remove half his thyroid and radiation treatment he will make a full recovery. I post this because we caught this early only because he had a really bad bladder infection that required blood work. If you want more info on his story, see his facebook page: Also we want to hear from anyone that has had to deal with this issue as well to find out how the treatments went and so forth.
