There is an ever-growing list of agility sanctioning organizations. The ones you’ll hear about most often in the US are NADAC, AKC, and the USDAA (see below for a more complete list of national and international groups). Each organization has its own rules and style. For example, NADAC courses are spread out and focus on speed. They often challenge the handler to send their dog through the course at a distance. USDAA courses are “tighter” and more technically challenging.
If a dog has a clean run without any faults, it’s called a qualifying run or a “Q,” and they’ll get points added to their official record. If they get a good score, they may also receive a placement ribbon. Winning a first place is a lot of fun, but in the grand scheme of things placements don’t matter until you reach high levels of competition. However, the Qs are important – with enough points, your dog will earn a title. A title is a certificate of accomplishment. As you earn each title you stick it to the end of your dog’s name, so Fido’s name can eventually start to look like Jonas’s. Very snazzy.
Want to attend a trial? This is a good way to check out a club before you take classes. Check their events page to see if they have any trials/shows coming up. Most shows are held in parks and are open to the public. The atmosphere at most of these local trials is fun and casual. Handlers will usually be happy to answer your questions – just make sure you don’t interrupt them when they’re at the ring preparing for their run.
You can start training your dog before they're of age to compete. Begin by working on basic obedience and teach your puppy to sit, lie down, come, heel, and stay. Your puppy will also benefit from attending training classes where they will learn basic obedience and get used to working around lots of other dogs and people. Having your pet take and pass the AKC Good Citizen Test is a helpful step.
