Consistency may be hobgoblin of little minds in terms of the need for human creativity. With respect to dog training, however, inconsistency is the quickest way to reduce the experiences effectiveness.
Dogs thrive on predictability. In fact, their ability to grasp cause and effect is at the very root of training. Operant conditioning is predicated on the fact that dogs will begin to associate events with consistent outcomes. This notion of consistencys importance must be extended to the overall process of dog training.
A dog is likely to best respond to a system in which regular actions produce regular results. Too often, dog owners fail to be entirely consistent. In the dogs mind, these lapses in regularity convey a sense of randomness to the process and make it difficult for the pet to associate his specific behaviors with specific results-the key to training. Dogs will excel when they are taught that things happen for specific reasons. When surprises occur it undermines the whole of the training process.
A successful trainer will retain consistency and will not deviate from an established course.
