In that case...too late and unfortunately I believe...THAT (not solely that one sire)...has lead to the problem with yorkshire terriers and liver shunt today. People are continuing to breed animals with liver shunts in their lines. They know it's an hereditory condition but NOT how it's passed and until that can be determined the only safe thing to do...is remove animals from a breeding program who have produced LS puppies.
If a puppy's BAT levels came back elevated...then a protein C test should be performed. That test would indicate whether having more intensive testing for LS should be performed....
I'm not a breeder I have no knowledge of whose lines have produced liver shunt puppies...I want to avoid purchasing one...the only way I feel safe would be purchasing a puppy who has been tested.
