Every agility course is different. At a trial, the courses are designed by the judges and are not shown to competitors until the day of the event. Handlers are given a short "walk-through" period before each event to learn the course and plan their strategy. Teams may incur faults during their run for incorrect obstacle performance or by taking obstacles out of order or in the wrong direction. Time faults may also be incurred if the team takes longer than the standard course time to complete their run. Courses typically include 15-20 obstacles with allowed times of 30 - 60 seconds. Some common types of courses include:
Regular or Standard: designed to test the skill and speed of dog and handler teams on a variety of obstacles.
Jumpers, Tunnelers, Weavers, & TouchNGo: designed to test the speed and handling skills of teams on specific types of obstacles.
Gamblers and Snooker: two games/non-standard classes in which handlers must devise their own strategy to collect as many points as possible in an "opening sequence", then correctly complete a set "closing" sequence" within a time limit.
