Parents who test fine on bile acid even a full liver scan..can and do produce LS pups. Research studies done by DR. Tobias was the one who said they can skip 10 generations.
There are known carriers and breeders must avoid breeding a male and female with a common carrier..but research tends to indicate one LS carrier in a line does not mean a problem for the breeder..it is when both male and female have the same carrier.
You can contact DR. Tobias and she will give you a list of pedigrees with LS problems...but please remember BOTH parents must have these dogs in their line..the gene is contributed by both parents.

I was talking to a breeder who only had a 5 generation pedigree..a 10 generation pedigree would revealed a common carrier..many breeders have nothing more then a 3 gen ped..useless for LS IDing.
