Dog Agility is a competitive sport that tests a person's skills in training and handling of dogs over a timed obstacle course. Competitors race against the clock as they direct their dogs to jump hurdles, scale ramps, burst through tunnels, traverse a see-saw and weave through a line of poles in an obstacle course configuration designed to challenge handler's competitive and training skills. With scoring based on faults similar to equestrian show jumping, dog agility has become an exciting spectator event.
