The Positive Valence of Food

Behaviors tend to follow emotion. You come in the door and your dog is happy to see you. What's the emotion? Happy and excited. How am I going to solve it? If I solve the behavior that's bothering me, let's say I smack her. As it solved the problem, solves my problem. She no longer jumps on me because she's afraid of being smacked. But if she was, I would walk out the gate, drop a handful of food and continue on my way. Problem solved. And if she's not having the emotion of frustration, the behaviors I don't want to see don't follow.
