person A: Our little chihuahua was diagnosed with an auto-immune disease when she was just a puppy.
person B: Oh no!  Were you able to take care of him with medicine or treatments?
person A: Yes_comma_ for about 6 years.  Then she got pancreatitis and kinda went downhill from there.  We just lost her in February.
person B: I'm so sorry!  I know how hard it is to lose a pet!  I hope you are not sad for too long.  It sounds like you did everything you could to give it a great life.
