Thanks for the advice, I just assumed that since my friend didn't tell me the results that they wouldn't come back until today or something. I still haven't asked what the results were though. I think the fast makes sense -- the vet just said that Bella's system needs a rest until tomorrow. Its been way out of whack and needs time to "repair" itself.

But Bella is doing so much better -- those pills help incredibly. She hasn't vomited or had any diahrrea, and she isn't just laying around. She was barking up a storm today when she heard her brother, Duke, barking. But she is still confined to her crate to rest, no matter how much she wants to run around the shop with the other dogs! My friend said that Bella wasn't sleeping at all before, but she is sleeping very well now.

I'll talk to my friend tomorrow and ask her if there was an official diagnosis.
