My basset/lab mix is having some aggression issues. He had no issues the first year that we got him, but this year have noticed that he is more vocal and protective around us and the house. He has started scaring some of the children in our neighborhood when we go out for walks, and he used to have no problems with kids. Sometimes he has no problem with them, but other times he will try to jump up on them, barking and they run away which makes him want to chase them. When this happens, sometimes it seems as if he is trying to play, but other times he seems to be more aggressive. If he sees anyone, even people he usually knows and likes, when we are out on a walk, he will start to snarl, growl deeply and then bark visiously. He's taken an instant dislike to bikes and skateboards. He almost went through the screen on our storm door the last time he saw the mailman delivering our mail. Is there anything we can do to stop this behavior?
