Have you heard about this? http://www.science20.com/news_articles/type_1_diabetes_cured_dogs-103093 The researchers claim to have cured Type 1 Diabetes in dogs. They achieved this with a single session of various injections, with a so called gene therapy. After 4 years the dogs remained symptom free. "Dogs treated with a single administration of gene therapy showed good glucose control at all times, both when fasting and when fed, improving on that of dogs given daily insulin injections, and with no episodes of hypoglycemia, even after exercise." "The study is the first to report optimal long-term control of diabetes in large animals. This had never before been achieved with any other innovative therapies for diabetes. The study is also the first to report that a single administration of genes to diabetic dogs is able to maintain normoglycemia over the long term (more than 4 years)."
