I spoke many times with Mr. Hartl about the beginnings of a cross breed of the dog's natures. Crossing the wolf and the dog is not easy ... involvement could not be submissive dogs. Wolf- female needed a dominant dog. I think that this - the original genes are present in nature csv, still clearly visible. Working with this dog is complicated .... like to get involved in their breeding dogs quiet and easy to use. But my heart belongs to a dominant dog
