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.
Obedience training usually refers to the training of a dog and the term is most commonly used in that context. Obedience training ranges from very basic training, such as teaching the dog to reliably respond to basic commands such as "sit," "down," "come," and "stay," to high level competition within clubs such as the American Kennel Club, United Kennel Club and the Canadian Kennel Club, where additional commands, accuracy and performance are scored and judged.
Seesaw: This obstacle looks just like what you might see on a playground, with one plank supported in the middle, so that either side can be lowered toward the ground. The dog will start at one end and walk to the other, while the plank shifts with the dog’s weight. Some clubs require that this obstacle have grips or treads on them, as a safety measure.
Money. Therein lies the rub. One of the drawbacks to training competitively is the cost. Between class fees and trial entries, this can be an expensive sport. That doesn’t have to deter you, though. Many clubs offer significant discounts on training and entries if you work at their trials, which was a huge help for me. I earned quite a few free or nearly free classes by working trials. The fees for junior handlers (-18) are also considerably more affordable.
Clicker training, a common form of positive reinforcement, is a simple and effective dog training method. Although it is still fine to train your dog without clicker training, many people find it helpful. With clicker training, you can easily and effectively teach your dog all kinds of basic and advanced commands and tricks. It's fast and easy to learn how to clicker train your dog
