In terms of closeness of a breeding based on genetic relationship, I think a sire to daughter or a litter mate brother to sister are about the same. However, the pups from a parent-offspring mating would be expected to be more alike or uniform than from a brother-sister mating. The genes are similar but are recombined differently. Also, if you are interested in perpetuating the old dog's genetics the sire to daughter would be better. I have had a couple of brother-sister litters that were not bad.
