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 and the Canadian Kennel Club, where additional commands, accuracy and performance are scored and judged.

Obedience implies compliance with the direction or command given by the handler. For a dog to be considered obedient rather than simply trained in obedience, it must respond reliably each time the command is given, by what is commonly known as its handler. A dog can go through Obedience Training and not be obedient. If a dog is referred to as being Obedience Trained, it should comply immediately with every command its handler gives. In the strictest sense an Obedience trained dog is an obedient dog.

Training a dog in obedience can be an ongoing and lengthy process depending on the dog, the methods used, and the skill and understanding of both the trainer and the handler. The level of obedience the handler wishes to achieve with the dog is also a major factor in the time involved, as is the commitment to training by the handler. Obedience training is often a prerequisite for or a component of other training.

The actual training of the dog can be done by anyone. The trainer, owner, or a friend. Typically the individual who is caring for and living with the dog participates and trains the dog, as they will be the one who will be giving the commands. The relationship and trust between the dog and handler are important for success.

Basic or beginner's obedience is typically a short course ranging from six to ten weeks, where it is demonstrated to the handler how to communicate with and train the dog in a few simple commands. With most methods the dog is trained one command at a time. Though there may or may not be a specific word attached to it, walking properly on a leash, or leash control, is often the first training required prior to learning other commands.

Working Dogs have always learned to obey commands related to the work that they historically performed, such as when a sheepdog moves a flock of animals in response to a shepherd's whistled directions, or a hunting dog searching for (or chasing down) quarry or leaving the treed quarry at the hunter's command.

In the twentieth century, formalized dog training originated in military and police applications. 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 behaviours.

At a basic level, owners want dogs with whom they can pleasantly share a house, a car, or a walk in the park. Some dogs need only a minimum amount of training to learn to eliminate outside (be housebroken), to sit, to lie down, or to come on command (obey a recall ). Many other dogs prove more challenging. New dog owners might find training difficult and fail to make progress, because they expect dogs to think and act like humans, and are surprised and baffled when the dogs don't.

Dogs who 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.
