" Because behavior is under the control of its consequences, obedience training is about providing consequences to the dog. Life is a never-ending series of:"If you do this, this happens, if you do that, another thing happens." There are two kinds of things that happen in life, good things and bad things, so there are four kinds of consequences: good stuff can 1) start and 2) end; bad stuff can 1) start and 2) end. Your dog is constantly trying to start the good stuff, end the bad stuff, avoid ending the good stuff, and avoid starting the bad stuff. He's playing his entire environment, including you, this way. If you can recognize this and exploit it, *voila!* Control of the dog. "
