information Erbgraf Zingo v. ThÃ¼ringen (1900, Belling v.GrÃ¶nland or Junker Slenz v.ThÃ¼ringen x Freya v.ThÃ¼ringen) caused much confusion. His dam was accidentally mated by both dogs. However after looking at his progeny the experts decided that Junker Slenz had definitely been his father. For the time Zingo was a good dog, a well built and compact Dobermann with a well shaped head. He also sired some exellent progeny.
But in the Dutch Studbooks Graf Belling v. Thuringen is mentioned as the Father of Erbgraf Zingo v. Thuringen.
