Excellent news. There's a high-percentage chance that our BoBo has a bacterial infection called leptospirosis. Best guess is that he acquired it by drinking water at his first field event of the year, when the fields were still contaminated with river water from Hurricane Irene.
He is doing much better this morning and if he keeps improving, he will come home tomorrow. He actually ate this morning. *phew*
No word yet on the test for cancer and things of that nature.
