They are all different names for the same breed. “Doberman Pinscher” is the name recognized by the AKC. “Dobermann” with two n‘s is the name currently used by kennel clubs throughout Europe and other parts of the world (after Louis Dobermann, the breed’s creator). “Pinscher,” the German word for “terrier,” was dropped from the breed’s name in the mid-1900s as it was no longer appropriate for describing the current breed standards. “Doberman” with one n is the nickname for both “Doberman Pinscher” and “Dobermann.”
