The first Triple Crown took place in 2001 supported by the MidAtlantic, The Great Lakes and the Northeast Region Leonberger Clubs. It was resurected in 2013 and now takes place annually always featuring a large gathering of Leonbergers.

In 2013,the Great Lakes Leonberger Club, MidAtlantic Leonberger Club, Northeast Region Leonberger Club, and Leonberger Club of America enjoyed five days of fun and showing over Memorial Day weekend. Over 150 Leo Lovers gathered to show, celebrate, and socialize in New Castle, Pennsylvania. 2013 featured six AKC Pointed Shows, a Fun Match, and a Traditional Show. Everyone pulls together to make sure you have a great time and feel the hospitality!

The tradition continued in 2014 in Leesburg, VA in conjunction with the Middleburg Kennel Club and the Leonberger Club of America. Saturday held three events - the All Breed Show, the LCA Concurrent Specialty, and a Match put on by the Mid-Atlantic Leonberger Club of Virginia.

In 2015, the event has moved to Millwood, VA with another first for Leonberger events: back-to-back concurrent specialties. The 2015 Leonberger Triple Crown is sponsored by the Leonberger Club of America, Mid-Atlantic Leonberger Club of Virginia, Tarheel Leonberger Club, NJ Leos, Warrenton Kennel Club, and Old Dominion Kennel Club.
