Hello, sorry to hear about Quigley. Fever of unknown origin is a broad term for stating that the cause of the fever has not been identifies. In a puppy this young, the most likely cause is something infectious (viral, parasitic, or bacterial). Other inflammatory causes are less likely. You should continue to follow your veterinarian instructions, however, if the source remains undetermined, Quigley may need testing to include tick borne disease testing, an abdominal ultrasound, and even chest x-rays. Hope this helps and best of luck.
