I am so sorry I'm just seeing this. I'm glad to hear that she seems to be getting better though. I know how stressful it is when they are sick and you don't know why. I went through something similar when Zoee had her "attacks" which we think might have been seizures.

This is definitely something you could not have prevented or predicted. It sounds like it just happens (whatever IT is). So please don't beat yourself up over it. You are a wonderful dog mom, don't you forget it!
