Liver shunt is not dominant, as far as we know. Therefore, it takes a male and female that carry the gene to have the POTENTIAL to produce a LS puppy. There are well known LS producers in some of the large lines and it is important to watch the back end of the pedigree to not inadvertently cross two together. If I had an LS puppy,heaven forbid, I would go outside the pedigree totally to breed either dog. Better to stay away from any common link. |
