Harley used to do Agility, a sport involving a course involving jumps, tunnels, elevated walks and other "obstacles." The dog and handler run the course together, the dog going over or through the obstacles while the handler runs alongside. These photos show Harley at his very first agility competition in October 2011. Harley is now (January 2018) twelve and a half years old and has some arthritis, so he retired from agility several years ago.
