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.
