I'm no expert on pedigrees but he looks very handsome. I was looking at a litter of pups and the mother's father has Ellute von der Mohnwiese in there as well. The dog I am talking about is Nivo vom Lubarser Schlösschen and he, from what I can tell, appears to be popular with some working line breeders in Australia. From what I can gather from the breeders I have talked to, Nivo pups are popular with the police. I'm not sure if Nivo and the dog you are looking at are similar but it's just a comment from me and my experience. I'm sure someone more knowledgeable can contribute.
