At the beginning of this month, Chief got diagnosed with AIHA. He's currently on several kinds of meds and was managing to still eat pretty well up until the past couple days. Yesterday he only ate breakfast and he hasn't had a full meal yet today. All I've been able to get into him are treats. I have been trying to not over do it so he will still have room for real meals but he's turning his nose up at everything! His activity level is super low, I think he has an especially sad look in his eyes, and I'm wondering if he's trying to give up. How damaging is it for a dog to go off it's feed? I know with cats there is concern about them coming down with Fatty Liver Disease from a sudden hunger strike, but what about dogs?

Does anyone here have experience with AIHA? Things are getting pretty frustrating over here. Our boy doesn't seem to be getting worse.
