So, I just talked to the vet and Cali's liver enzymes, kidneys, electrolytes and blood glucose are OK. He said that her white blood count is high even for a greyhound and indicates some kind of an infection. She had two more vomiting, with clear liquid with a little blood and no more diarrhea - probably because she's empty - and since being hydrated seems a little more interested in what's going on around her. That sounds a little more like my girl.
They are prepping her for x-rays to see if there's some kind of blockage and giving her antibiotics but still don't know what's wrong with her.
I'm still worried about her but they are hopeful she can come home tomorrow and we'll have answers soon.
Thank you for all your good thoughts.
Vicky
