Inherited cateract

Our Axcium Casanova "Cosmo" has been at stud here in Norway since age 1. Out of his 46 offsprings in 11 litters Norway, plus 13 offsprings in 3 litters in Sweden and 9 pups in 1 in Denmark he has proven to be a good studdog and given breeders really nice dogs to continue breeding on.
But I would like to ask you who has offsprings out of him to be careful when choosing breeding-mates to your dogs out of Cosmo. 2 offsprings has been confirmed with inherited cateract and another offspring is diagonsed with PTHVL.
We do NOT know if he is proven carrier as he never has been test-bred but we choose to inform about this as we know it.
If you want more information, you are welcome to contact me.
