Gosh, I just saw this thread.

I worry all of the time about my lab, and what I would do if something like this were to happen. The breeder we got her through is fairly reputable, but not the best - her parents were screened for genetic defects and whatnot, but you never know

I'm so sorry for your poor Zoey. She's so lucky to have a Mom like you, who will love her and pamper her no matter WHAT. Please bear that in mind.
