I have studied a little in genetics and to my understanding both parents would have to be carriers of the fault and that if you matched them with a partner that did not carry the gene that the pups would be fine. However the pups would also be at risk if bred with a dog that carried the same gene. You have to think every dog could carry the gene without it showing as the animal only inherited it from one parent. An animal that has the fault visable has inherited it from both parents but can only pass on its half of the genes so the puppy has only this half. Does that make sense, its easier to draw a diagram.
