I am so glad you never bred either one of them!
So many people don't realize that it can take years for those genetic "flaws" you mentioned to show up. My Lady was nearly five before her genetic "time bombs" started going off.
That's why no one should breed a pet quality puppy who parents have not been health tested (knees, hips, eyes, thyroid, & liver) from an unknown line.
I'm so glad you are doing it the right way!
