Please excuse my ignorance in asking this question, but as more genetic testing becomes readily available (i.e., for fanconi and other genetic disorders), and based on testing results, breeders are going to be culling (for want of a better word) dogs/lines they have bred or had planned to breed, aren't we [necessarily] further narrowing our already small gene pool if entire lines can no longer be bred due to genetic deficiencies? If so, how are breeders going to deal with that? I know we've got some new blood that is, at this point, backstage (being Fanconi tested?), but it seems to me like the B breed, as we know it, is, heartbreakingly, in a vortex into oblivion…or am I being too pessimistic (I know I tend to be)?
Also, regarding irresponsible breeders: It seems to me that trusting them to breed Fanconi carrier to Fanconi clear would be an impossible supposition. JMO, of course.
(Please don't think I'm against genetic testing, I'm all for removing genetic disorders from the gene pool.)
