I have two dogs and they bark everytime someone drives by. When someone come to my door I have to literally squeeze out my door and stand outside to be able to talk to that person. How do I train them to stop barking? If my company comes in the house when they are both petted by that person they will stop, but then they will not leave my company alone..ugh so frustrating. They are bigger dog ( 3 year old Lab and 1 year old Rottweiler) and do not like to be ignored, when I have no company they listen excellet and well behaved
