[1] It was originally devised by Charles L. "Bud" Kramer from the obedience practice of "doodling"—doing a variety of interesting warmup and freestyle exercises.
Unlike regular obedience, instead of waiting for the judge's orders, the competitors proceed around a course of designated stations with the dog in heel position.
There are currently seven sanctioning bodies for Rally-O in the United States: the American Kennel Club (AKC); World Cynosport (formerly the Association of Pet Dog Trainers (APDT)); Canine Work and Games (C-Wags;) and Canines and Humans United (CHU).
The United Kennel Club (UKC) added rally obedience to their program as of January 2009, and the Swedish Working Dog Club (SBK) added it in July 2011. International Canine Events (ICE) offers a Rallye Challenge title.
Examples of errors include the dog leaving heel position when not cued to do so, the handler holding the leash too tightly, or miscounting steps on certain exercises.
The most obvious difference between the two is the ability to reward the dog with food in the ring under specific conditions in World Cynosport rally.
It has added variations on rally courses, such as Zoom - which has no stationary signs, and requires 4 legs to title.
CARO is similar in many respects to both AKC and World Cynosport Rally, with the addition of some agility elements.
In Switzerland, Rally Obedience has existed since 2002, the last rules from 2008 are based on the work of Bud Kramer and the APDT and were updated in 2012.
