Dog agility is a dog sport in which a handler directs a dog through an obstacle course in a race for both time and accuracy. Dogs run off leash with no food or toys as incentives, and the handler cannot touch either the dog nor any of the obstacles.
Points are deducted for missed obstacles and excess time taken over a set standard. Obstacles include "Weaving Poles", as shown above, "Jumps" over hurdles ,through hoops, and broad jumps. There are also "Tunnels", "Ramps" and "See-Saws" to negotiate.
On the Northern Beaches of Sydney there are Dog Training Clubs which offer training and competition for this and other dog sports.
On the Resources page of this site there are links to these Clubs which cater for Agility. It is great fun for both handler and dog, and a good way to improve your fitness.
