It would be a good idea to test Cory anyway. This will reinforce the lineage. I will be testing Shadow as well. Shadow is neutered, but it goes back into the line pattern. I went to a blood draw and had his blood taken, so I just have to send in the request now. Is it important? Probably not to a lot of people, but I want to have my own peace of mind, and this reinforces what Robyn has been striving to achieve-health! Shadow is brother to Sugar's sire, by the way.
