Sorry, I did not know the dog came from Carol Ann and is a full af. My second response is automatically the Fanconi health issue and testing.
I hope she gets better soon and no longer has a temperature.
For Bs with an unknown background, I recommend urine strip testing starting at two since there have been affecteds showing symptoms at three. I do this for all of my rescues but I also do the DNA test.
That would have been mine also….. about testing for Fanconi..but I remembered that she came from Carol Ann............
