The rules describe certain turns in a 440- to 500 yard track. In the real world, dogs track through urban settings, as well as through wilderness. Dogs must be at least one year old to participate. In an Agility Trial a dog demonstrates its ability to negotiate a complex course which should include a walk over a bridge, jumping through objects, going through tunnels, and pausing on command. There are different height categories so each dog is tested fairly on the course.
Agility is exciting for the dogs, handlers and spectators.
Many of these clubs also offer classes and less formal sanctioned trials for beginners. These events are designed to allow a dog to demonstrate its ability to herd livestock under the direction of a handler. Stock used at the trials can be sheep, cattle, goats, or ducks. There are also non-competitive herding clinics and instinct tests given by AKC clubs across the country. Coursing dogs are scored on speed, enthusiasm, agility, endurance, and their ability to follow the lure.
