Barking at children

Tonight Zachary started barking and would not stop barking at children. Lisa has come to the door with her little girls and Zach started barking a would not stop. We even tried taking him outside to see if that would make a difference. He did stop, but only for a short time. When he was little we exposed him to some childern, but I guess that no longer matters.
