@morsesa - As I noted the two health issues for Basenjis, Fanconi and PRA, there are DNA tests as both are recessive genes and both of these are late onset. There is NO reason since 2008 when the first DNA test for Fanconi came out and then the direct DNA test a few years later to ever produce either of these two affilications. Is this what you are referring to and note Fanconi and PRA are NOT limited to the US, these were world wide affilications? The results of these tests (which are saliva samples done by owners/breeders) and the results are public knowledge and can be found at www.ofa.org. You will find many Basenjis thorough out the world that have been tested. If this is not what you are referring to, as asked by eeeefarm, please be more specific. Keep in mind that all Basenjis are decendants of the original Basenjis imported in the 1940's. If (and there are) people producing Basenjis with Fanconi it is because they are not testing before breeding, therefore not responsible breeders.
