I am so sorry your pup is so ill. I hope she will respond to the meds...she is certainly in a wonderful place where she will received great care!
I will keep her in my thoughts and prayers. Please keep us posted. We have a member whose pup had histoplasmosis and she recovered. You might want to read this thread about it...it is a bit long and goes off topic, but it is a good read:
