One thing that I have learned in life is to accept that things are not all black or all white. Life is shades of gray and just because someone sees a different shade of gray than you do, it doesn't mean their shade is right or wrong, its just different. ~ Robyn Dubbert
@tanza yes my mistake it was tested with OKC I got papers to prove it.. she was born with the disease
Are you referring to OFA? If so then I would wonder if the pup's sire/dam were not the real sire/dam of the pup you got? Only if they are Afflicted with the Fanconi gene (the pup) would they develop Fanconi? Did the paperwork from OFA say "clear"?
One breeder from San Diego (Rancho Penasquitos) retired from their day jobs and moved to Texas; Bob & Terry Reed of Illusion Basenjis. Another San Diego breeder (Spring Valley) passed away almost 2 years ago; Doug Joy of Basenjis of Dune. Not all reputable breeders are visible on the BCOA website. Some don't want their kennels named because they do not breed very often. You should contact the breeder liaison via email for more breeders in California and other nearby states.
The local breed club for southern California is The South Coast Basenji Fanciers. They can help you find a local breeder. The quickest way to get in touch with them if through their Facebook page: https://www.facebook.com/SoCalBasenjiFanciers
And as one of the posts advises:
"Stay patient. A lot of inexperienced people are buying puppies they are ill prepared for, from greeders who do not take their basenjis back.
I suspect in the next 6-8 months we might see/learn of an influx of basenjis needing homes."
