@hdolbow:
Before this Fanconi test , which can come back indeterminate, ANY SINGLE BASENJI sold, from a breeder OR a puppy mill could have fanconi.
Someone will correct me if I'm wrong, but indeterminate is between clear and carrier…not carrier and afflicted/probable afflicted. So if there is an inderminate, it is as good as clear or carrier as far as pet ownership is concerned. In a breeding situation, with an indeterminate, I believe a responsible breeder would wait for the new test to be made available before breeding an indeterminate dog if the plan was to breed it with a carrier.
And while your statement is true that ANY SINGLE BASENJI sold could have fanconi (prior to the DNA test that started last year)...prior to the test being available last year, reputable/responsible breeders weren't making breeding decisions without the consideration of fanconi and without researching the dogs in the pedigree lines...
My understanding from the test results that have been posted on OFA...while some results were surprises, many were what was expected. To me that says that many breeders did a good job of figuring out which lines/breedings ran the risk of fanconi and planned accordingly.
Puppy mill breedings do not take into account any health information...period...puppy mill breeding is purely for profit, it is as simple as that.
