Wow, you guys are lucky to have had a quick diagnosis! We were also lucky in that respect, as we had treated Dirtbike with antibiotics for about a week for a resp. infection, but when it didn't get better and the vet saw the sore that wouldn't heal - we had the dx of Blasto in about 10 min. Lots aren't so lucky.
She will be very picky, but you have to keep the calories in her no matter what - and the med won't work unless there's something in her stomach, preferably fatty, like butter. Dirtbike refused all food and liquids for a while, and we fed her Ensure Plus by bottle, and I would shove peanutbutter down her throat, tricked her into eating things- she had no choice but to swallow it. She did drink, usually after we "fed" her. It took a long time to get her to eat regularly, nothing made her happy except Cesar dinners, which are tiny and expensive. A big dog can go through a lot of those!
It broke my heart to see DB through the first month, she was so sick. At one point my dad, my mom, and my husband were all in the hospital at the same time, and I had to take care of her on my own. I spent many sleepless nights talking to her, crying with her, treated her like a child, so don't feel silly. Dogs are blessed, and they depend on us to do their best for them.
It was also scary to read stories here, many of them are not good outcomes, but there's alot of helpful information, and a few bright spots, like Wilson.
Dirtbike is fine now, but still taking her medicine. The only sign of sickness is that she takes a nap after the pill, and pants maybe a bit heavily but it's hot. The wheezes are gone, nose is back to normal, no sores.
Otherwise, she is running, swimming, playing, hunting, eating like a horse, and is back to being the alpha dog.
Sorry I didn't check in sooner, you must be wearing yourself out. I wish the best for you guys - hang in there, because it gets worse before it gets better, but you sound like you have a great chance to pull her through.
Best to you-
