@karabovm - You might try https://www.kusa.co.za/index.php kennel club in south africa, they might be able to give you some leads.... or try and find a dog show and visit them. Also you can ask other breeders of other hounds if they know of one.
Pam Geoffroy [Eldorado] is President of the BCOA and Debbi Hauri [Mata Hauri] is a longtime Basenji breeder.
I am sure you would love a pup from either of them :-)
@Nemo:
Here's the link. http://www.basenji.org/learn/
Go to "screening breeders" at the top.
That is a great list…and great explanations of why those questions are important.
Two very good sources for selecting a responsible breeder
