@debradownsouth My editing of my post was terrible. Thank you for clarifying what I meant to say. I did have a female that tested "probably affected" in the early testing. She was bred to a clear (later most accurate test) and produced 3 pups who were all carriers (again, the latest most accurate test). While I found it necessary to put her to sleep at age 14.5 (seizures related to brain damage from being hit by a car) she never developed Fanconi or any symptoms of it. None of the pups were bred for various reasons (development, temperament) although one did become a lure coursing champion.
My posts are sometimes incoherent, lol. You did fine, I just wanted people to not be confused that a carrier could develop Fanconi.
Breeding even an affected to a clear wouldn't have produced affected. Before the test, no one had a choice but to go with what was there. Responsible people like you didn't use the excuse of it not being "perfect" and did the best available. Making it to that age is wonderful, especially with her brain damage.
