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.
Prong collars must never be turned inside out (with the prongs facing away from the dog's skin), as this may cause injury against the body and head.  Plastic tips are occasionally placed on the ends of the prongs to protect against tufts forming in the fur or, in the case of low quality manufactured collars with rough chisel cut ends, puncturing the skin. Like the slip collar, the prong collar is placed high on the dog's neck, just behind the ears, at the most sensitive point.
Here at 3 Lost Dogs, we’re all about giving dogs jobs. Boredom is the leading cause of behavior problems, because dogs were bred to WORK. All this sitting around at home with only a daily walk or run does not a happy dog make. They need some kind of challenge, or they’ll find their own. And it’ll usually be something like digging up the yard or barking incessantly at all who dare pass the front window. Agility provides the perfect combination of physical exercise and mental stimulation to keep Fido entertained and out of trouble.
Certain breeds, such as Doberman Pinschers, German Shepherds, Border Collies, Labrador Retrievers and Golden Retrievers, have reputations as being easier to train than others, such as some hounds and sled dogs. Dogs that have been bred to perform one task to the exclusion of all others (such as the Bloodhound or Husky), or that have been bred to work independently from their handler (such as terriers), may be particularly challenging with obedience training.
Herding breeds like border collies are the masters of this game, which is why you’ll see a ton of them at trials, but they’re not the only players. Chihuahuas, pit bulls, huskies, hounds, even Great Danes. You name it, my dogs and I have probably been shown up by it at some point. Surprisingly, certain toy breeds like Papillons have a real knack for agility.
"Training with John gave me the tools to better communicate with my pup. He is very patient, and willing to work on specific problems or challenges with each person with whom he works. My dogs behavior has improved in all aspects, and our bond is stronger because he understands what is acceptable and what is not. Thank you for helping me get there, John."
Dogs that demonstrate the previously mentioned basic skills, as well as walking reasonably well on a leash and a few other minor tasks, can be tested for and earn the American Kennel Club's (AKC) Canine Good Citizen certification. While not a competitive obedience title, a CGC certification demonstrates that the dog is sociable, well behaved, and reliable in public settings. Some insurance companies will waive breed restrictions on dogs with CGCs, and many states have passed resolutions supporting and encouraging CGC certification as a yardstick for canine manners and responsible dog ownership.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
