Dux is a dog that is not ours, we are keeping him for a friend. We are also evaluating him while he is with us. He is highly inbred with a coi of 37%. I reached out to the breeder or breeding back ground but got no reply. I would say it was an attempt to get back to Sir Henry. It is possible that we may breed him before returning him to the owner. He appears to be a very nice dog.
