@debbie said in reputable breeder?:
@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"?
