I am not an expert on dogs, but I do own a lovely Cavalier King Charles female who has learned not to bark at everything. Here are a few tips that might help. 1. when the dog barks, first investigate what it is barking at. If nothing serious, just speak to the dog, and explain "It's ok, nothing to worry about. then when the dog starts barking again, put yourself on the level with the dog, look it in the eyes, and say "Shhhh" , and give it a stern look. Then say, "No!" firmly. Do this everytime in a calm but firm way. 2. Another thing that always works, is that once the dog realizes it has done something you do not approve of, take action. Put the dog in it's crate, shut the door, and walk away. Leave the dog there for a short time alone. It's doggie time out. Pretty soon doggie will understand it's actions were a no no. My dog actually goes and gets in her crate if I discover her unwanted behavior. She knows she was displeasing.

I do so hope so because he is such a precious dear it would be a travesty to have to give him away.
