As noted by Debra, go to www.basenji.org and search for breeders. Most of the reputable breeders are listed here, but not all. Go to https://basenji.org/index.php/about-basenjis/is-a-basenji-right-for-me, there is a link about screening breeders. These are questions you should ask potential breeders. They should provide you with links the the OFA testing base. DNA testing for Fanconi and PRA are public knowledge. Here is an example of one of my listings on the OFA database.https://www.ofa.org/advanced-search?f=sr&appnum=1415062. For sure Fanconi DNA and PRA DNA must be done, but most responsible breeders also test for hips, thyroid, eyes... however, those results are not always posted a public. But if done, the breeder would have certificates of the testing. Breeders typically show their Basenjis... some do performance events. This activity shows not only the correct conformation (showing) but that and/or performance shows temperament. If you have other questions, please contact me. You can find my email on my website link noted below. And I will comment as Debra said.. many breeder webs are not kept up to date, sad but true...I have always pushed that breeders keep their sites up to date as all "puppy back yard breeders do because people search the internet, but most you can find also on FB.
