Hi There. Sorry to have you join us but you couldn't be with a better group of dog owners. We have been down this same road and will help you every step of the way, but hold on it is a very rough ride. My will was EXACTLY like your dog: coughing, lame, lungs full of consolidated mass. That was Sept 21st. On Oct 3rd he was well enough for me to carry him to the car and take him home: 12 days. The Itraconazole is an appetite suppressant AND the effects of the Itra as it kills the fungus leaves them feeling exhausted and listless.
As everyone else has said he must eat, a little at a time is fine, normal, but offer food often. Warm food has stronger flavour and odour. Cheese is easy to swallow. I sometimes put a little piece in Will's mouth and gently held it closed while the flavours circulated in there. He would spit the food out, think about the taste and then pick the piece up and eat it. He would eat one or two little pieces and we would be thrilled. Offer lots of water, even if you have to get it into him in a syringe.
I would make sure they are checking the eyes because the retreating and advancing fungus head for the eyes in a lot of cases.
And most of all, I read every single post for weeks and weeks back learning something from almost every message.
Wilson3, Jen, Evayola were huge supporters when I came on the board, then weluvmoose, cls, pandomania..... and lots of others joined in and together we researched, asked questions and posted our findings. Collectively I know for sure we know more than my vet clinic here in Toronto and they have acknowledged as much. So, run things past your clinic but don't let them slough off your concerns about anything; especially the eyes. It seems they were good about getting a quick diagnosis so that is very positive. With blasto, timing is everything and when you do your best and are armed with lots of knowledge you have a good chance for a happy ending. Good luck and stay with us.
