A simple way to add complexity and a handling challenge to a home course or a intermediate class is to add wings!
For practice, you can add wings to any jump, though for competition they’re only used on bar jumps. Wings add distance for the handler and dog, which can be a real problem for Velcro dogs! They also change the appearance of jumps the dog is used to. Changing views keeps dogs from becoming situation oriented, and not completing a jump because it looks different and new.
