Thanks for all the thoughts, ladies!
I just got done with the vet. I got them to show me how to put the IV on my dog and give her shots so I don't have to leave her there (they are closed for the holiday anyway). You learn something new every day! I now know how to give IV fluids to animals. Anyway, the dog is doing a lot better. The final toxicology screening won't be in until monday but the fluids seem to be perking her up.
She's the most ridiculous dog... the longest we've ever gone without going to the vet since we've had her is three weeks. 
Anyway, thanks for all the well wishing. Today is already MUCH better. I get to work from home instead of the office and I'm going to BLEACH my entire house to make sure there's no residual bacteria from what she has.
On the flip side, I think I'm done with my vet. She doesn't give us straightforward answers and they overcharge us for everything (not something I can keep doing with a dog with this many issues).
Does anyone have a vet in the inner east-bay area or San Francsico proper that they love? Maybe even a holistic vet that you've worked with that you like?
I'm glad we decided not to go camping with her this weekend. Looks like she'll need to stay in.
