The incorporation of the American Hackney Horse Society took place early in 1891. The idea occurred to owners of Hackney horses throughout the western states and indeed residents of several parts of the country had actually taken steps to form a similar society some months prior to the organization of the AHHS. It was not until advances were made to the Council of the English Hackney Society by the directors of this association that action in the United States was formally ratified by the authorities of the parent society, and assurance of affiliation obtained.

The American Saddlebred remains the ultimate show horse, high-stepping and elegant. A show horse is a spectacle of beauty and grace but is also an intense athletic competitor. American Saddlebreds compete in four primary divisions in the show ring: Five-Gaited, Three-Gaited, Fine Harness and Pleasure. Each division has its own "look," and competitors should be groomed to perfection. Five-gaited, fine harness and show pleasure horses are exhibited with full manes and tails. Five-gaited horses are shown with roached, or trimmed, manes to accentuate their long, fine necks.

The American Dutch Harness Horse Association is a registry for high stepping show horses with the Dutch Harness Horse as a founding element.
