Hi Beth,
I am sorry you are facing such a hard time right now. I am really sorry that your vet is so limited! I, unfortunately have been suffering along with a vet that is way lack luster in her performance. So I am really happy that we are here to help. I think that everyone on here, with their combined hours of research on Blasto, have the time equivalent of a PHD!
First, let me recommend that you read some of the previous posts that I just moved up for you. See: Idea: Knowledgable Vets . Some people on here have had wonderful experience with knowlegable vets. *Maybe* your vet won't be offended if you give her these other vet's names to contact for information.
I also moved up a previous post about Sporonax (Itraconazole) that you might find useful. See: Sporanox, Generic, Compounded, ending the controvercy.
Ketoconazole is no longer the drug of choice when treating blastomycosis because of it's harsh side effects. However, since Missy hasn't officially been diagnosed with Blasto (though her symptoms are alarminly similar), Ketoconazole is a broader spectrum anti-fungal, that doesn't cost the arm and leg that Itraconazole can. So until you can get a diffinitive answer on exactly what Missy is fighting, I don't know if switching to Itraconazole is best right now. Untill Gunner was officially diagnosed with Blastomycosis, they put her on Ketoconazole. I do hope your vet warned you to keep an eye out for any signs of liver disfunction, another side effect of keto.
The emergency vet that saw Gunner when she was at her sickest point, told us that one small can of a/d is equivelant to one large can of dog food. I think giving Missy 5 cans in a day is a bit over the top. To feed Gunner, I just mixed a can of a/d with a can of ensure and whizzed it with a hand held blender and then *slowly* squeezed it in her throat with a syringe. Slowly is the key because if you squeeze too quickly, it shoots in (and out) or hits their gag reflex. So just ooze it in just about 5-10 cc's at a time. Your vet should give you all the syringes you need for free. See post: What to feed a dog that is no longer hungry... lots of good help in there.
Does Missy have diarhea or just loose stools? Gunner's stools were pretty loose for a couple of months. They were also dark and turned black in a couple of hours. Missy will probably have weird looking bodily functions for a while. I know Gunner had me running here and asking all kinds of questions. I have since managed to calm down a bit but one thing I did learn, that in the world of Blasto sufferers, the weirder the symptom, the more "normal" it seems to be.
Vomiting is also a common side effect of the antifungal drugs. It is important to give them with some food at least and the more the better, and better yet if it has some fat content as well.
Hang in there. We are all rooting for you.
