No problem
Yes, the pups still need to be tested...Even if the parents are tested, and they don't have a liver shunt, that does not mean that they aren't carriers of the gene. If they are carriers, their pups can have a liver shunt. As far as I know, there is no positive way to test if parents are carriers. So, they may be carriers and not have liver shunts, but may pass the gene down to their pups and they can have liver shunts. Does that make sense? It's kind of confusing the way I wrote that! LOL
So anyway, yes, the pups need to be tested as well.
