To discipline a dog with positive reinforcement, we need to focus on behavior-change rather than behavior-stop. We set our dog up to succeed rather than lash out. We decide what we want our dogs to do instead of bark, lunge, and bite. And, maybe most importantly, we help our dog feel differently about his world and the people and other animals in it. When we change our focus in this way, we naturally shift from confrontation to collaboration. We start working with our dog rather than working on him. Create an environment where your dog can get it right over and over. Teach this instead of that, for example, if a dog barks at people who ring the doorbell, we can change the meaning of the doorbell and make it a cue to run to another room where he can wait behind a baby gate. Positive reinforcement in this case would include happy talk from the human and food. We are actually influencing our dog’s emotions, specifically, we are affecting a change in how he feels about the doorbell.
