Confused. Really. We have breeders listed in AKC, and in breed clubs. OFA maintains health certifications. Why reinvent the wheel? It's unlikely breeders who haven't tested or didn't report bad results will just open up to you.
Then you have Sally's database...which is extensive. A look at her work on just Basenjis might give you an idea of the enormity of what you want to do. So I really must be missing what your reasons and goals are.
