Welcome all101

. Glad you found us! But I'm so sorry your kiddo is sick.
I don't want to write too much info, bc I think you might be overwhelmed. So, I think I'll just do a few bullets:
-- Getting rid of mites can be a difficult process; is there any way you could find a vet who speaks English or use a translator for this?
-- Almost all dogs will develop a yeast infection (fungal) during and after treatment for mites; this must be addressed, but it may have to wait until later (you may need to treat symptoms of yeast *now*, and treat the cause later). For treating
after, mention Diflucan or fluconazole.
-- You mentioned a vaccine - is it safe to vaccinate the puppy at this time? I would just consider the state of this pup's immune system, with the meds you're giving and the diseases he is fighting, and whether or not he should be getting vaccines at this time
