Your pet gets some kind or kind of payback when he barks. Otherwise, he would not take action. Find out what he gets out of barking and take it off. Don’t give your pet the possibility to continue the barking action. If he barks at animals or people transferring to the living room screen, take care of his action by closing the curtains or adding your pet to another available room. If he barks at passersby when he is in the yard, bring him into the homely house. Never leave your pet outside unsupervised all full night and day.
