"The Miniature Australian Shepherd, North American Shepherd, North
  American Miniature Australian Shepherd, and/or Toy Australian
  Shepherd breeds are not recognized as a  variety of Australian
  Shepherd by ASCA.  The club considers such dogs to be a distinct and
  separate breed and will not accept them into its registry.

  "Our bylaws state that ASCA's purpose is: 'To encourage members and
  breeders to accept one breed standard for  the Australian Shepherd as
  approved by the Club as the only standard of excellence by which
  Australian Shepherds shall be judged.' It is the mission of this club
  and the mission of its members to preserve the breed rather than
  change it."
