If your puppy barks to try to get your attention try to ignore it. Don't make eye contact or say anything. If you look at him or yell at him, you are giving him attention, which is just what he wants. If this doesn't work, try squirting a water pistol at him as soon as he starts barking (don't let him see where it's coming from), clap loudly, blow a noisemaker, or make a sharp, silly sound to star
