@AJs:
Fanconi carrier can be bred to Fanconi clear. It's the Possible Affected's that should not be bred and Carrier should not be bred to Carrier. That said, please get advice from other breeders before you embark on this. It's not a way to make money. From what I'm seeing on these forums, most breeders are lucky to break even.
I looked at the website for your bitches' breeder…I'm appalled at the idea of referring to pups as "products" as this breeder does. Also, on looking at the pictures of their pups, I see they refer to a Tri as a Black and White...ehh...huh?
I will only say that in regards to breeding possible Affected, I disagree with not using them. Now, personally I would never use a possible Affected bitch, however I would and plan to in the future use possible Affected and/or collected Affected males. We can't afford to lose the gene pool by discounting these dogs. Granted you must breed to a Clear and you will get all Carriers, however management of these Carriers, bred back to clear, is IMO needed to not lose more out of the gene pool then we have already.
