I don't know if most of the dog owning public is aware of the levels that we pass through when teaching a dog a certain command. Here are the four levels that I usually think of:
1) Demonstrate to the dog what you want him to do.You can do this by positioning or luring your dog into position. Dogs need to be shown what to do, because they don’t naturally know the things we take for granted that older dogs have already been taught. Obviously they don't understand our verbal cues, and need to be shown what they will correspond to in the future. In the Demonstration phase, the command is verbalized in conjunction with the luring or placing the dog into correct position.
