If I remember the Dog Whisperer videos correctly little dogs make noise because they are scared/nervous.
I think that's probably at least somewhat true. Our Shih Tzu is not a barker. He's probably the quietest dog we've ever had, and all the rest have been medium/large dogs. But he's also super confident. He's been charged by numerous larger dogs and he just looks at them like "WTH is your problem?" He has the same "WTH" reaction when he's around other little dogs who are barky.
The only thing that bothers him are rumble strips. :E
