My Mommies are all raised in my home and evaluated before they are ever bred. I have to see excellent health, good loving personality and good social skills. They are genetically tested (blood panels, eyes checked by a cerf approved canine eye doctor, and knees and hips) before they are ever bred and all come from good solid lines.
Pedigrees are only as good as every dog in them. I research my heritages completely before breeding either dog. This is also the reason I use only AKC registered dogs.
