Utviklingen av rasen

48 crossings with (pure) GSD were involved with 41 different GSD (some mated twice or three times). Below a scheme in alphabetical order. The first mentioned are the GSD, the second the wolves and F1's-F5's they mated with. Marked on white background are the matings which went on with offsprings which we have today, on grey background the crossings which didn't go on but "died out". Some GSD's are mentioned more than once because they mated 2 or three times. Totally 5 wolves were involved in creating the breed.
