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 generally run off-leash with no food or toys as incentives. The handler can touch neither dog nor obstacles, except accidentally. Consequently, the handler's controls are limited to voice, movement, and various body signals, requiring exceptional training of the animal.

In its simplest form, an agility course consists of a set of standard obstacles, laid out by an agility judge in a design of his own choosing on a roughly 100 by 100 foot (30 by 30 m) area, with numbers indicating the order in which the dog must complete the obstacles.

Courses are complicated enough that a dog could not complete them correctly without human direction. In competition, the handler must assess the course, decide on handling strategies, and direct the dog through the course, with precision and speed equally important. Many strategies exist to compensate for the inherent difference in human and dog speeds and the strengths and weaknesses of the various dogs and handlers.

You do not  have to compete to keep on with agility. Agility is for ex an excellent tool  to give anxious dog confidence.

Courses in agility are held at most of the Dog clubs and also at the Breed and Special clubs. To participate the dog should be at least a year old and has reached it's finally size. The dog should have a good basic obedience before it goes on agility course.
