Working cow horse or reined cow horse is a type of Western riding competition in which horse and rider are tested for ability to work cattle. In Reined Cow Horse, the horses are judged on accuracy, timing, and responsiveness in reining work, cow work, and for some events, herd work.  Reined cow horse events  are "open" to all breeds and held Nationally by the National Reined Cow Horse Association (NRCHA), and locally by Affiliates of the NRCHA.  Click HERE for more  information on the history of the Reined Cow Horse tradition.

The Atlantic Reined Cow Horse Association (ARCHA) was founded in 2006.  We are a family oriented association offering opportunities to show for everyone from the experienced rider on a highly trained horse to beginners and children just becoming familiar and comfortable with riding in the show ring in front of people. We promote beginner classes for newcomers to familiarize themselves and their horses with the event, as well as riding clinics geared to help all levels of horses and riders.
