Oh, poor little Cody I'm sure it's very upsetting for your family to your little guy losing his fur. Personally, I would not risk him getting diabetes in order to cure the baldness problem. Hormone therapy is very taxing on all body systems. Of course, wait to see what the specialist says and advises. But as has been said, hairless or not, he will always be handsome, with or without a coat. And most importantly, all be loved. Let us know what the specialist says, and hugs and kisses to your Cody!
