Thank you all. I'm happy to hear positive outcomes, skin or fur. There was a ton of info in the links that gmac posted, and although this seems to be highly treatable I still worry. I just don't want this to be happening to him. I worry constantly. Is he feeling ok? Is he in pain? Aside from licking his lips he's the same Austin, we just went for a walk, first one in a while and he really seemed to enjoy it. I'm trying to stay upbeat around him, I do most of my crying in the shower! I'm sure he can feel my upset and I don't want him upset. I just pray the treatment works, that he can tolerate it, and that he's with us for a long time to come.
