Ozzie, my 3 year old Boston, has always been just a sweetheart and loved everyone until recently. He is becoming more and more territorial. He goes crazy barking and running up to people and running around them like he going to attack them. Its anyone that pulls in our driveway, especially delivery people. He is usually good to listen but not during this behavior.
He is a doggie out of control when he sees a stranger. Any suggestions would be greatly appreciated...This behavior just started about six months ago.
