My 6mo lab pup got sick 4 weeks ago and at first my vet thought it was just a infection but after a week and no improvement we went back and was diagnosed. With blastomycosis a fungal infection. He has swollen glands and is starting to have lesions. His left eye is swollen up and looks like he has cataracts. We have been giving eye itraconazole drops and itraconzole 100 mg tab. Is therr anything else that we can do? Are we fighting a loosing battle? Will he be blind? I dont feel my vet is being completely honest?
