What the Lion is to the Cat - the Mastiff is to the Dog

The noblest of all family, he stands alone, and all others sink before him. his courage does not exceed his temper and generosity, and in attachment he equals the kindest of his race. --Cynographia Britannica 1800

Club Objectives

The objectives of the club are to encourage and promote the selective breeding of quality purebred Mastiffs and to do all possible to bring their natural qualities to fit the standard

  •  to encourage the organization of independent local Mastiff Specialty Clubs in those localities where there are sufficient fanciers of the breed to meet the requirements of the American Kennel Club 
  •  to urge members and breeders to accept the standard of the breed as approved by the American Kennel Club as the only standard of excellence by which Mastiffs shall be judged 
  • to do all in its power to protect and advance the interests of the breed and to encourage sportsmanlike competition at dog shows and obedience trials 
  • to provide for the welfare of the breed through a program of Mastiff Rescue and continuing education 
  • to conduct sanctioned matches, obedience trials, and specialty shows under the rules of the American Kennel Club.

The MCOA conducts a roving Independent National Specialty in the spring of each year; Check the Club News page for a link to more information about the upcoming Specialty.
