My 11 year old Bix has a nasal tumor and she is not doing well. I have had a Homeopathic vet percribe Aurum Metallicum LM4, Calcarea Carbonica LM/3, and then Carcinosin every fifth day. Has anyone used these with any success? I am concerned about the 'proving' being harsh as she is already not doing well,can't sleep, appetite going (almost gone), pus discharge, etc.
