How does the American Kennel Club (AKC) currently register the larger German Spitz types (Grosser, Mittel, Klein)?

Answer

It does not register them under the German Spitz name

The AKC currently recognizes only the Pomeranian as a distinct breed, electing not to register the larger varieties like the Grosser, Mittel, or Klein under the German Spitz classification within the United States.
