Extreme Vertical: This is the high jump. Dogs start at the 20-foot mark on the dock and jump up to grab a bumper toy extended 8 feet from the end of the dock over the water. Starting height is 4 feet, six inches, and the toy rises in 2- inch increments as the competition progresses.
Big Air: This is a long jump in which the dog may be placed anywhere on the 40-foot dock. The dog runs, then jumps in the water after a throw toy is thrown by its handler. Distance of the leap is judged from the end of the dock to where the tail set of the dog breaks the water’s surface.
Speed Retrieve: In this timed event, a bumper toy is suspended 2 inches above the water with a starting indicator light above it. The dog is placed at the 20-foot mark on the dock. When the light turns green, the handler releases the dog. The clock stops when the dog has pulled the toy from the Speed Retrieve bracket. Source: DockDogs
