Also called dock diving, dock jumping is a competition where dogs jump from a dock into a body of water in an attempt to achieve great distance or height. Dock jumping is much like the human long jump or high jump, but with water.
In distance jumping, or “Ultimate Air,” the handler throws a toy off of the dock in an attempt to get the dog to jump as far away as possible. Distance is measured at the place where the tail base meets the water. Jumps are usually recorded digitally for accuracy.
The newer “Ultimate Vertical” is a high jump. A bumper is placed at a predetermined height. As competing dogs reach it, the height is recorded and bumper is moved up. The winner is the only dog that can reach the bumper at its highest position.
