Hi leelapops,
Afraid I have the same problem with my little Westie, Misty. Also with my last Westie.
Think it is a territorial thing with dogs, but I was forced to get a small plastic watergun, (childrens toy) and fill it with water.
When Misty barks continually, I shoot the water pistol at her face and she hates it. It does not stop the barking permanently, but it does quieten her at the time.
In a way, it is a good thing that our dogs do bark, as it also deters people from breaking into our homes. lol
