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.
There are many factors that go into choosing the right training school for you and your dog. Certainly distance is a consideration; however, convenience shouldn’t be the only factor that influences your decision. Other things like training methods, appropriate classes for your needs, compatibility of the instructor’s personality with yours, and certifications of the instructor should also play a role.
Whenever you’re training your dog, it’s important to get as many family members involved as possible so everyone’s on the same page. If you are telling your dog “off” when he jumps on the couch and someone else is saying “down,” while someone else is letting him hang out up there, how on earth is he ever going to learn what you want? Consistency will be the key to your success.
Last, basic obedience training isn’t just for dogs that compete in obedience, agility, or trick competitions. Obedience exercises are important for all dogs, especially high-energy breeds that need mental stimulation as well as physical exercise. Simple behaviors like sit, down, stay, come, and leave it are essential for a well-behaved pet. You can challenge your dog even more by teaching him more advanced behaviors like “go to place,” formal heeling, to roll over, etc. The old adage — a tired dog is a good dog — is not incorrect. However, a mentally and physically tired dog is even better.
Dog intelligence is exhibited in many different ways, and a dog that might not be easy to train might nonetheless be quite adept at figuring out how to open kitchen cabinets or to escape from the yard. Novice dog owners need to consider a dog's trainability as well as its energy level, exercise requirements, and other factors before choosing a new pet. Very high intelligence is not necessarily a good thing in a companion dog, as smart dogs can require extensive daily mental stimulation if they are not to become bored and destructive.
In the twentieth century, formalized dog training originated in military and police applications, and the methods used largely reflected the military approach to training humans. In the middle and late part of the century, however, more research into operant conditioning and positive reinforcement occurred as wild animal shows became more popular. Aquatic mammal trainers used clickers (a small box that makes a loud click when pushed on) to "mark" desired behavior, giving food as a reward. The change in training methods spread gradually into the world of dog training. Today many dog trainers rely heavily on positive reinforcement to teach new behaviors.
