I don't know about these bloodlines. Since you are from Norway, do you know of any people that have purchased from these breeders? Maybe you could check with them? Not sure if there is a way to check the parents out on line? So glad your post went through. I hope someone here has the answer to your question. If they don't answer this thread, maybe start a new thread about " How to track the bloodlines on my new puppy." Or something written like that, to attract people who would know how to go about finding out that information. Good Luck.
