Well, she hasn't vomited since about midnight last night. The wierd thing about it was that it never seemed to phase her...she'd be playing, stop and puke, then right back to playing.
I know she didn't eat anything here...BUT I did have to board her Friday and Saturday night, maybe she got into something there.
Anyway, I just got home from the vet. They are a little concerned about the vomiting but since she's been fine today, they don't think they will postpone the spay UNLESS she vomits while in their care. They are really concerned about the hypoglycemia though. I told them that she hasn't had an episode since about January, but since liver shunts are so common in yorkies, they are doing some blood work to check it out. They will call me later on with the results of the CBC and CHEM and if all goes well, she will be spayed in the morning.
