Simone Update 8/10
All of the tick disease tests have come back negative, so her low platelet levels aren't being caused by a bacteria. Darn! That would have been the quickest and easiest fix.
As of yesterday, her platelet count is now at 21,000 (a four-fold increase). We're still ~150,000 shy of being back in the normal zone, but hopefully she'll get there. Her neutrophils are a little elevated (which can indicate a bacterial infection), so the vet has asked us to keep her on the antibiotics for now even though the tick titres came back negative. We go back in for bloodwork on Monday again for the next check.
It's sounding more and more like immune-mediated thrombocytopenia, so it sounds like she will be on steroids for the rest of her life (in addition to her twice daily thyroid and phenylpropanolamine). Soon we're going to need one of those pill cases just to keep it all straight! The vet also had us put her on 2 tablets of maximum strength Pepcid AC to help her stomach cope with the current high doses of steroid.
We're glad her eyes look better...the redness has pretty much disappeared. The weight gain has begun from the steroids though, as she's up 4 pounds in only 2 days. I shudder to think of what it will be on Monday! Poor puppy worked so hard to lose all that weight, and now it's going to pile itself back on. Hopefully it won't be too hard for her to lose again later :)
We'll continue to keep you posted.

Thrombocytopenia
They took blood out of three of her legs and gave her a giant shot of vitamin K (19 mL...I've never seen a syringe that big) to help her coagulate better, and then sent us home to wait by the phone to hear the results of the blood work.
At 6pm the vet called. Simone's platelet levels are dangerously low (5,000...they should be at 165,000). This means she is not able to clot properly. She has a tentative diagnosis of thrombocytopenia. This might be caused by an autoimmune disorder (then it would be called immune-mediated thrombocytopenia), in which her immune system has suddenly decided to target her platelets, or it might be caused by something else, like canine ehrlichiosis (a bacterial infection transmitted by a tick). As we were in Northern Nevada and California in the last 5 weeks or so, the tick bite might be a possibility. They are running a tick titre on her blood now; we should have the results in 6 days and know for sure. In the meantime, they have started her on a high dose of steroids and an antibiotic (in case it's the ehrlichiosis). She will be getting her blood checked every other day to see if her platelet count starts to rise. We'll know more once the tick titre comes back and after she's had her first few platelet counts.
If it's the autoimmune disease, then she'll be on steroids for the rest of her life. If it's caused by a tick, then the antibiotic should kick it eventually. We've been told it could still be caused by something else entirely (cancer was mentioned as a possibility not to be ruled out just yet), but we won't go there until we have to.
Keep your fingers crossed for us.
