We have a Maltese puppy who is about 8 or 9 months old. We take him on two walks everyday that are about 10-20 min long. When we pass people he gets very aggressive if we do not allow him to go up and say hello. People think he is mean, but he is barking because he is excited and wants to meet everyone. Of course, many people do not want to stop and play with puppy so we keep on walking and he gets upset. If we move our hands anywhere near him and do not allow him to go up to someone he bites us. Same if we are on our porch and people walk by, and if we are standing still on the side walk and cars go by. Anyone else have this experience. I am not sure how to react to him in a manner that will help him.
