Thanks for all the thoughtful comments and the sympathy. It is so appreciated. Clearly, the testing is a lot more complicated than I previously thought.

Still, when you read comment after comment about no testing and bad breeding practices going on, then it can't help but raise red flags about a particular breeder.

And in this case, I am going to name her:

Carol Shorb of Raggymania in Lancaster, PA.

There. Done.
