BEN: What’s the best way to get a pooch to behave? Reward him (or her)! Rewarding good behavior works better than punishing bad behavior (at least with dogs). Think about it. No one likes to be yelled at, and that includes canines! Dogs are a lot happier if their owner isn’t yelling “STOP BARKING!” My dog Yoda barks a lot. So what I do is this: If he stops barking when I ask him to, I make a little tiny clicking sound with a clicker (like a castanet) and give him a treat and say, “Good doggie.” This encourages him to behave.
