My friend has a Maltese and that was the breed I was planning to get at first, I couldn't find one during that time, so I looked at yorkies and ended up getting my boy Bailey, I would not trade him for anything, he is the sweetest most loving little guy and he never barks in my house, he barks in the car in his seat and when he is out playing with other dogs, I think that is pretty normal, my friends Maltese barks at everything.  You will find all dogs are different and special in their own way, If I get another dog it will be another yorkie.  Good luck in your search!
