Interesting article about training your dog to modify his/her behavior through environmental means. I've been telling people to do this for a while and recently found an article where they gave it a name: Behavior Adjustment Training. In a nut shell, you basically put a dog in a situation where he/she would normally react badly to a stimulus, then take away the stimulus only when the dog stops reacting or the reaction lessons. For example, if a dog barks at a person, instead of leaving with the dog or the person leaving, you wait until the dog stops barking before the person (or you) leave. Where previously, the dog barked and the person left, now when the dog stops barking or doesn't bark at all,  the person leaves.
